Preface
The primary requirement for the Third-Generation Mobile Communications System in Japan is to
establish a “Global System”. Therefore, Japan has carried out its studies in a flexible manner
based on a world-wide perspective to create a globally common technology, while cooperating with
the standards bodies of other countries and regions.
The European Telecommunications Standard Institute, ETSI, decided to adopt W-CDMA for the
FDD mode of UTRA, which is a radio transmission scheme very similar to the Japanese proposal.
Also in the U.S., T1P1 is likely to harmonize their activities with this decision by ETSI. Within
TIA, various systems including TDMA are still under discussion, and TR45.5 is continuing its
studies on wideband CDMA (cdma2000). In Korea, wideband CDMA is studied as one of the
candidates for the radio transmission technology of IMT-2000. Thus W-CDMA is not only a more
competent technology than other systems, but it is also the most promising system to be applied as a
global system. Therefore, it is necessary to continue the harmonization activities at an
international level, in order to achieve a common solution among various wideband CDMA
proposals.
This document describes the outcome of the studies and activities carried out in Japan to refine its
radio transmission technology proposal. Since the primary objective of Japan is to standardize a
globally common radio transmission technology, continuous efforts towards global harmonization
are needed. This proposal may be further modified in the future, if such harmonization activities
require such changes.
Therefore, Japan is willing to continue international harmonization activities even after submitting
this proposal, so that the key parameters, etc., of this proposal can be matched with those of other
standards bodies by the end of September 1998, which is the time frame for the evaluation group to
submit the evaluation report to ITU.

Introduction
This document describes the radio transmission technology (RTT) for the third-generation
mobile telecommunications system proposed to ITU-R. The scope of this study focuses
on a terrestrial system. Association of Radio Industries and Businesses (ARIB), Japan,
selected Wideband CDMA (W-CDMA) as the radio transmission technology to be
proposed for IMT-2000.
Prior to this selection, ARIB investigated a number of candidates for the radio transmission
technology of the third-generation mobile communication system that could satisfy the
requirements and objectives for an IMT-2000 system and its services. After two years of
intensive studies with hardware demonstrations and field trials, the Wideband CDMA (WCDMA) concept was selected in January 1997 as the most suitable and the most verified
radio transmission technology for the third-generation mobile communication system.
After the concept selection, ARIB started the refinement activities for the W-CDMA
system proposal in order to make a better technical solution and at the same time to seek
the possibility to harmonize with proposals from other regions. The proposal presented
herewith is the output of such refinement activities, which were carried out with an aim to
compile a global IMT-2000 system based on the best technologies.

RTT proposal of Japan
1.2 System Design Concept
Below are the main features to be supported by the third-generation mobile communication
system:
-
High degree of commonality of design world-wide
Compatibility of services among different third-generation mobile communication
systems and with the fixed network
High service quality
High speed data services
Worldwide use of small pocket terminals.
The requirements for the third-generation mobile communication system are :
-
Global system
Ability to provide new services and capabilities such as multimedia services.
Efficient use of radio resources.
Flexibility to support various operational environments.
Ability to provide seamless services through the connection with other networks,
the Internet, etc.
The radio transmission technology of the third-generation mobile communication system
should be able to support multimedia, personal as well as intelligent functions.
Specifically, the system should meet the requirements recommended by ITU-R such as
advanced multi-rate services up to 2Mbps and a quality comparable to that of the fixed
communication networks. At the same time, the system should aim to realize a simple cell
structure, easy channel management, high subscriber capacity (at least equivalent to the
capacity of half-rate PDC system or better) and low transmit power.
RTT proposal of Japan
2. General Description
2.1 W-CDMA Key Features
The key technical features of the W-CDMA radio interface are summarized below.
•
Highly Efficient Spectrum Utilization
In order to improve spectrum utilization efficiency, different technologies such as
transmitter power control or VOX technology, where signals are transmitted only
when there is speech, can be applied to CDMA. The adoption of these
technologies makes it possible to achieve an effect equivalent to when a
sophisticated technology such as dynamic channel assignment, etc., is employed in
other radio access schemes. In other words, this means that a system with high
spectrum efficiency can be realized easily.
•
Release from frequency management
Since CDMA allows the use of the same frequency in adjacent cells, a frequency
assignment plan becomes no longer a necessity. With FDMA and TDMA
systems, however, frequency assignment is necessary. In particular, in a real
environment where base stations are deployed, it is quite difficult to assign
frequencies while giving considerations to irregular propagation patterns and the
impact from geographic topology. In addition, while imperfect frequency
assignment design could rather lead to lowering the spectrum utilization efficiency,
CDMA can get rid of such concerns.
•
Low mobile station transmit power
By means of technologies such as RAKE receiving, CDMA can improve the
reception performance, thus, the required transmit power at the mobile station can
be reduced with CDMA systems when compared to TDMA systems. Since
intermittent transmission is employed in TDMA, the peak power to send
information symbols will increase in relation to the number of timeslots.
On the
other hand, the peak power for CDMA can be kept low since continuous
transmission is adopted. This is also advantageous in terms of keeping the impact
in electromagnetic environment to a minimum.
In TDMA, where various transmission rates are supported by setting up the
number of timeslots to be allocated, the same level of peak power as the power
needed for transmitting the highest rate service will be needed even for mobile
terminals dedicated for voice service.
•
Use of independent resources for uplink/downlink
In CDMA, an asymmetrical uplink/downlink structure can be easily supported. In
other access methods such as TDMA, it is difficult to assign the number of
timeslots for uplink and downlink separately for one user. It is also difficult to
realize this with FDMA, because the uplink/downlink carrier bandwidth needs to
be changed. On the contrary, the uplink and downlink rates can be set up
independently in CDMA systems by the use of independent different spreading
factors for uplink and downlink for each user. Consequently, radio resources can
RTT proposal of Japan
be used efficiently also in asymmetric traffic communications such as Internet
access.
Furthermore, the wideband nature of W-CDMA can offer improved efficiency for
the following points as well.
•
Wide Variety of Data Rates
The use of a wider band carrier makes it possible to provide higher transmission
rates. It also allows providing services efficiently, even in a situation where lower
rate services and higher rate services coexist. This enables not only speech/fax
services but also high-resolution video services to be supported in the same band.
Accesses to the Internet can be done at the same rate as from a fixed
communication network.
•
Improvement of multi-path resolution
The RAKE diversity receiving technology improves the reception performance by
combining the individual paths after they were received separately among multiple
paths. The use of a wider band carrier can improve the capability to separate
these multiple paths, which consequently reduces the required transmit power.
This makes it possible to lower the transmit power of mobile stations, and at the
same time brings down the interference power, which leads to further improve the
spectrum utilization efficiency.
•
Statistical multiplexing effect
The use of a wider band carrier increases the number of channels accommodated in
one carrier. Further improvement in the use of frequency can thus be expected,
thanks to the statistical multiplexing effect.øøIn particular, when a relatively fast
data communication is performed, the efficiency drops in a narrow-band CDMA
system, because the number of channels accommodated in one carrier is limited.
On the other hand, the statistical multiplexing effect derived from the use of a
wider-band carrier can greatly enhance the efficiency.
•
Reduction of intermittent reception ratio
The adoption of a wider-band carrier can enhance the transmission rate of the
control channels. When a mobile station is in a standby mode, it receives only a
part of the control channel to save battery consumption, which results in the
reduction of the intermittent reception ratio. This contributes to achieving longer
standby hours of the mobile station.

For the TDD mode, in addition to the use of all slots within a frame, the TDMA
structure where only part of the slots are used will be adopted.
The following describes the key features of W-CDMA technology to outline the
physical layer of the radio interface.
•
As for the bandwidth, besides the 5MHz bandwidth, expandability to 10MHz and
20MHz is also secured in order to provide flexibility of operation. At the same
time, a bandwidth of 1.25MHz is defined as well.
•
The chip rate is specified taking into account of the hardware feasibility and the
possibility to obtain great spreading gains in the bands used. For instance, when
the 5MHz band is used, the chip rate is set at 4.096Mcps. Fig. 2.3-1 gives the
rough image on the interrelation between each chip rate and data rate.

Interrelationship between data rate and chip rate
•
200 kHz carrier raster enables carrier spacing to be flexible and minute, and
improves spectrum utilization efficiency.
•
Both FDD and TDD modes are applied as the duplex schemes of the proposal.
The combination of FDD and TDD enables highly efficient use of spectrum
depending on the conditions in each region and at the same time offers high degree
of flexibility. Most of the key parameters including the chip rate, the frame
length, and the modulation/demodulation schemes are made common to both
modes.
•
Inter-cell asynchronous operation that does not require precise synchronization
between base stations was adopted for the proposal, so that freedom for
deployment of base stations to indoors and outdoors can be secured. However,
the proposal can also adopt inter-cell synchronous operation in order to provide
flexibility of operation.
RTT proposal of Japan
•
As a solution to implement multi-rate transmission, variable spreading factor is
used for uplink, and orthogonal variable spreading factor for downlink, considering
the ease of hardware realization. It is possible to use multi-code transmission for
high-speed transmission, etc.
•
Convolutional codes are employed for channel coding. Turbo codes that offer
better error correction performance are applied for high-speed data transmission.
•
Spreading codes have a two-layered structure of spreading codes and scrambling
codes. In downlink, the scrambling codes are assigned specifically to each cell,
(see Fig. 2.3-2), while they are assigned specifically to each user in uplink. Since
there are plenty of scrambling codes, the codes can be assigned to each cell without
any constraints. Spreading codes are orthogonal, and all codes are used
commonly for all cells, minimizing the interference between users within the cell.

Two-layer spreading code allocation
Coherent detection using pilot symbols is used as a detection method.. The pilot
symbols on the downlink are time multiplexed, so that the delay from transmitter
power control can be minimized. This is also advantageous to simplify the
receiver circuit of the mobile station. On the other hand, the pilot symbols on the
uplink are IQ multiplexed together with data, after they are spread with different
spreading codes than those for data. This enables continuous transmission when
variable rate transmission is carried out, and also can minimize the peak factor of
the transmit waveform. This solution is effective to reduce the impact in
electromagnetic environment and to alleviate the requirements on the mobile
station transmit amplifier. However, in the TDD mode, the uplink pilots are time
RTT proposal of Japan
multiplexed as similar to the downlink. This is because there is no advantages to
IQ multiplex pilots in a discontinuous TDD mode, and also because an asymmetric
uplink/downlink structure is desirable, when direct mobile-to-mobile
communication is taken into account.

A transmission scheme based on dedicated pilot is adopted as the transmission
method of pilot symbols. This scheme is beneficial for fast closed-loop
transmitter power control on the downlink. It is also possible to apply a common
pilot scheme, where the pilot symbols of common control channels are used by
each traffic channel. This makes it possible to further improve the performance.
The dedicated pilot scheme is an extremely effective solution in terms of securing
expandability to adopt adaptive antennas and other technologies in the future.
•
The packet data transmission is performed to support asymmetric uplink/downlink
transmission, and wide range of data transmission from low to high data rates.
For this packet transmission, adaptive channels depending on the traffic
characteristics are used. For example, when the traffic is low both on the uplink
and downlink, common physical channels (FACH, RACH) are used. On the other
hand, dedicated physical channels (UPCH) are used when the traffic is heavy on
either uplink or downlink, or on both links. Fig. 2.3-4 shows an image of control
information /packet data transmission.

FDD mode and TDD mode
In the W-CDMA proposal both an FDD mode and a TDD mode are utilized for its
duplex scheme. The combination of FDD and TDD makes it possible to use the
allocated frequency efficiently according to the frequency conditions of each region,
and thus increases flexibility. Most of the key parameters such as the chip rate, frame
length, and modulation/demodulation schemes are made common to both modes.
For this reason, the FDD mode and the TDD mode can be regarded as modes where the
frequency is used differently for transmitting and receiving the same bit flow generated
by the protocols of the common Layers 1, 2 and 3. This means that only a certain part
of Layer 1 of the radio interface, for example transmitter power control and diversity
schemes, needs to be operated differently for each of these two modes.
Another point of difference is the synchronization requirement between base stations.
The FDD mode can be operated both in synchronous and asynchronous operations,
however, the TDD mode requires synchronous operation based on guard time level of
accuracy.

Channel Structure
The channel structure consists of three fundamental channel definitions. The
first is the logical channels that are offered by Layer 2/MAC to higher layers. The
second is the transport channels offered by Layer 1 to Layer2/MAC. The third is the
physical channels that are handled within Layer 1. These channel types are explained
in this chapter. The mapping between logical channels and transport channels, as well
as the mapping between transport channels and physical channels are also described.
3.1.1 Logical Channel Structure
3.1.1.1 Logical Channel Definition
A logical channel is defined by the type of information transferred.
The logical channel structure of ARIB’s W-CDMA system basically follows ITU
recommendation ITU-R M.1035. The logical channel types shown in Fig. 3.1-1 are
defined for W-CDMA:
Control Channel (CCH)
Logical Broadcast Control Channel (L-BCCH )
Logical Paging Channel (L-PCH)
Logical Forward Access Channel (L-FACH)
Logical Random Access Channel (L-RACH)
Dedicated Control Channel (DCCH)

• Logical Broadcast Control CHannel (L-BCCH)
A point-to-multi-point, uni-directional channel for broadcasting system control
information from base station (BS) to mobile stations (MS). This channel transmits
information that changes over time such as SFN (System Frame Number), uplink
interference power etc.
• Logical Paging CHannel (L-PCH)
A uni-directional channel that simultaneously transfers paging information from
RTT proposal of Japan
BS to MS.

A uni-directional channel for transmitting control information from BS to MS.
This channel is used when the network knows the cell where the MS is located.
• Logical Random Access CHannel (L-RACH)
A uni-directional channel for transmitting control information from MS to BS.
• Dedicated Control CHannel (DCCH)
A point-to-point, bi-directional channel that transmits dedicated control
information between MS and BS.

switched mode.
• User Packet Traffic CHannel (UPCH)
A point-to-point, bi-directional channel that transmits user data in packet
switched mode.
3.1.2 Transport Channel Structure
3.1.2.1 Transport Channel Definition
The physical layer offers information transfer services to MAC and higher layers.
The physical layer transport services are described by how and with what
characteristics data are transferred over the radio interface. An adequate term for this
is ‘Transport Channel’.
Transport channels can be generally classified into two groups:
common channels, and
dedicated channels
The transport channel configuration is shown in Fig. 3.1-2.

- fast power control, and
- inherent addressing of MSs.
3.1.3 Physical Channel Structure
3.1.3.1 Physical Channel Definition
In FDD mode, a physical channel is defined by code and frequency, and, in the
uplink, also by relative phase (I/Q). In TDD mode, code, frequency and timeslot
define a physical channel.
The physical channel configuration is presented in Fig.3.1-3.

3.1.3.2 Perch Channel
This is a uni-directional channel from BS to MS, which is the subject of reception
level measurement for the MS to select cells. The first part of the timeslot in perch
channel is the time code multiplexed common pilot, which comprises of pilot symbols.
The second part is data symbols, and the last part is search code symbols (see Fig. 3.5-1,
Perch Channel Structure). In order to achieve fast cell selection at the MS upon
power-on, all symbols except for search code symbols are spread with only one
spreading code in the system.
Two different unmodulated search codes are
multiplexed to the search code symbols, and used for fast cell search (see chapter 3.5.1
for initial cell search procedure). The spreading codes used for the 1st search code and
2nd search codes are orthogonal Gold codes. .

In each group, PI parts are transmitted ahead of MUI parts.
In all groups, 6 information parts are allocated with a certain pattern in the range
of 24 slots. By shifting each pattern by 4 slots, multiple 288 groups of PCH can be
allocated on one Secondary Common Control Physical Channel.

Dedicated Physical Channel Structure
DPCH is further divided into two sub-channels, Dedicated Physical Data CHannel
(DPDCH) and Dedicated Physical Control CHannel (DPCCH). DPDCH carries user
and control information. Pilot symbols, TPC symbols and optional RI are transmitted
on DPCCH. Each connection may have more than one DPDCH, but only one
DPCCH.
The frame length on the physical channels is 10 ms, and each frame is split into 16
slots of length 0.625 ms, corresponding to one power-control period. Within each slot,
the DPDCH and the DPCCH are time multiplexed with one power-control command
per slot, in the downlink. One super frame consists of 72 10 ms-frames.
On the uplink, the DPDCH and the DPCCH are I/Q code multiplexed within each
radio frame and transmitted with QPSK modulation. Each additional DPDCH is
code multiplexed on either the I- or the Q-branch with this first channel pair. The
DPDCH and the DPCCH are code-multiplexed and transmitted in parallel.
The frames of the dedicated physical channels in principle take the structures
RTT proposal of Japan
described in Fig. 3.2.-4 and 3.2-5, for uplink and downlink respectively.
By
optimizing the positions of Pilot, TPC, RI and data part in the time slot, the transmitter
power control delay can be minimized.

Service Multiplexing
The fundamentals of service multiplexing are described in Fig. 3.3-1 and below.
One or plural transport channels which require the same service quality are
multiplexed to the same “channel coding and interleaving unit”.
The outputs from each “channel coding and interleaving unit” have the same link
quality. In order to obtain the each required service quality, different “channel
coding and interleaving unit” should be designed.
If one transport channel is too large for being handled by channel coding, it can be
divided into plural small channel coding blocks in “channel coding and interleaving
unit”.

Channel Coding
3.3.2.1 FEC
Two types of forward error correction (FEC) coding schemes, convolutional
coding and turbo coding are adopted to obtain efficient coding gains under various
environments. The application of convolutional code and turbo code is shown in Table
3.3-1.
1) Convolutional code
• Interleaving depth is depending on delay requirements and designed to be 10ms,
20ms, 40ms, and 80ms.
RTT proposal of Japan
2) Turbo code
• Performance strongly depends on its interleaving block size and the number of
iterations in decoding process.
• Even if one transport channel is too large for being handled by channel coding,
each interleaving depth should be expanded to the original large data block.
• Catalytic bit processing is used.
The concept of channel coding that contains FEC coding, spreading and
modulation are shown in Fig.3.3-2 and Fig.3.3-3. Details of spreading and modulation
are described later.

Catalytic Bit Processing (CBP) in Turbo code
As tail bits, 12bits are inserted in certain known positions of the turbo encoder
input data. The number of bits encoded by turbo code of R=1/3 has 12 more bits
compared to convolutional code of R=1/3 and K=9. After this, 12 bits are punctured
at the known positions of the coded data.
3.3.4
Rate Matching
Rate matching is used to match the coded bit-rate to the limited set of possible bit
rates of a DPDCH. In the uplink, puncturing and repetition are employed to match the
rate. In the downlink puncturing and repetition are used only for the highest rate,
while discontinuous transmission is used for lower rates.
3.3.5
Service Examples
The W-CDMA proposal of ARIB offers two basic service classes with respect to
FECs:
• Standard-services with convolutional coding only (BER=10-3)
• High-quality services with turbo coding (BER=10-6)
Multiple services belonging to the same connection are, in normal cases, time
multiplexed. Time multiplexing may take place after inner or outer coding. After
service multiplexing and channel coding, the multi-service data stream is mapped to one
DPDCH or, if the total rate exceeds the upper limit for single-code transmission, to
several DPDCHs.
The following subsections describe examples of the general channel coding and
RTT proposal of Japan
service multiplexing procedures for some of the services offered by the proposed RTT.
3.3.5.1 DCH (8 kbps)
Fig. 3.3-4 shows an example of channel coding and service mapping for DCH (8kbps).
Since the data rate is low, convolutional coding is used. The obtained DCH radio unit
is mapped to a physical channel DPDCH as shown in Fig. 3.3-5.

Spreading and Modulation
3.4.1
Spreading Code Type
The proposed RTT adopts a 2-layered code structure consisting of spreading
codes (spreading codes) and scrambling codes (long codes). Orthogonal Variable
Spreading Factor (OVSF) codes are employed for the spreading codes, in order to
preserve the orthogonality between different rates and spreading factors in both uplink
and downlink. The OVSF codes are generated from sets of orthogonal codes, e.g.

Scrambling is carried out after the spreading with spreading codes. In the downlink,
the scrambling code is a cell-specific 10 ms (40960 chips) segment of a Gold code of

length 2 -1. In the uplink, the scrambling code is a 2 Superframe (737.28 s) segment
41
of a length 2 -1 Gold code.
3.4.2
Downlink Spreading and Modulation
Fig. 3.4-2 shows the configuration of downlink spreader part where the in-phase
component of transmission data, DI, and quadrature-phase component, Dq, are spread
with spreading code, Ci + j Cq, to generate spreading signal, Si + j Sq. The spread
signals are fed to a quadrature modulator and mapped onto QPSK constellation. The
pulse shaping filters are root-raised cosine (RRC) with a roll-off factor of 0.22 in the
frequency domain.
3.4.3
Uplink Spreading and Modulation
Fig. 3.4-3 shows the configuration of uplink spreading and modulation unit. In
the uplink, DPDCH and DPCCH are spread to the chip rate using the OVSF codes. All
DPDCH channels and DPCCH channel are first spread by a spreading code, SCi. Then
signals are added with both I- and Q-branch and multiplied by a complex long
(scrambling) code, Ci + j Cq. The power of the DPCCH is adjusted by a gain factor, G.
If only one DPDCH is needed, only DPDCH1 and DPCCH are transmitted. When
multi-code transmission is performed, several DPDCHs are transmitted. Multi-code
RTT proposal of Japan
transmission can be employed for the highest bit-rates, typically above 384 kbps, and
several services of different rates can be transmitted in parallel while maintaining
orthogonality..
QPSK modulation is used for the carrier modulation on the uplink. The pulse
shaping filters are root-raised cosine with a roll-off factor of 0.22, as similar to the
downlink.

Radio Resource Functions
3.5.1 Initial Cell Search
The proposed RTT supports both asynchronous and synchronous inter-cell operations.
3.5.1.1 Inter-Cell Asynchronous Operation
W-CDMA employs an inter-cell asynchronous network to make the network robust and
easy to build even in areas where Global Positioning System(GPS) signal is not
available.
In order to realize smooth and quick cell acquisition even in an inter-cell asynchronous
cell network, fast cell search function is required. This function is provided by the
specific structure of the perch channel.
Fast cell search is realized by using a common spreading code for detecting of slot
timing and the scrambling code group identification code, so that search range of
scrambling codes can be narrowed down. Fig.3.5-1 shows the perch channel structure.

Fig. 3.5-2 Matched filter search for 1st search code
(timing modulo the slot length)
Search code symbols are spread only with orthogonal Gold codes, so that receiver can
easily detect them. With this perch channel structure, the speed of cell acquisition by the
MS can be significantly accelerated.
During the cell search process, the mobile station searches the base station to which it
has the lowest path loss. The initial cell search process is carried out in three steps.
Step1 : Slot/symbol synchronization step
Mobile station receives the 1st search code on the perch channel. Mobile station detects
the symbol timing as the timing of search code symbol by scanning the 1st search code
with a unique spreading code in the system. the slot timing of the strongest base
station can be obtained by the output from the matched filter for the 1st search code.
Step 2 : Frame synchronization and code-group identification step
Mobile station receives the 2nd search code on the perch channel with the slot/symbol
timing. The group of the scrambling code (consisting of Nscrambling codes) can be
RTT proposal of Japan
selected from the 2nd search code. The code group as well as the frame
synchronization is determined by identifying the sequence that gives the maximum
correlation value.
Step 3 : Scrambling-code identification step
Mobile station determines the exact scrambling code used by the selected base station.
The scrambling code is identified through symbol-by-symbol correlation over the point
of pilot and data of the perch channel, with all the scrambling codes within the code
group identified in the second step.
After the scrambling code has been identified, BCCH can be detected, and super-frame
synchronization can be acquired.
With the spreading and scrambling codes designated, the measurement of the received
levels of the perch channels in the neighboring cells/sectors can be performed by
reading the content of BCCH.

Fig. 3.5-3 Inter-Cell Async./Sync. Operation
In case of synchronous inter-cell operation, a specific code is used as the 2nd search
code. In this case, since a common scrambling code is used for all BSs, and the
identification of each cell/sector is based on the code phase offset. Since there is only
one scrambling code, Step 3 of the inter-cell asynchronous operation becomes
unnecessary, and faster cell search can be realized.
RTT proposal of Japan
3.5.2 Random Access
Random access is adopted in the Common Physical Channel. The physical channel
operated in random access mode is called Random Access Channel (RACH). In
RACH, access control for each message is handled independently.
Random access procedure is based on the slotted ALOHA algorithm.
•
A mobile station transmits a radio frame with a random access message on RACH,
and waits to receive an acknowledgement from the base station on FACH.
•
The base station transmits the acknowledgement on Ack-mode FACHs after
correctly receiving the radio frame from the mobile station on the RACH.
•
The random access message on RACH and the acknowledgement on FACH are
related by the same PID(Packet ID).
•
The mobile station does not transmit a new radio frame on RACH until the
previous radio frame is acknowledged or the time-out period has elapsed.
•
The mobile station retransmits the radio frame if it fails to receive the
acknowledgement.
Plural transmission timing offsets and/or plural spreading codes may be adopted to
decrease the probability of collision.
Example of Random Access Procedure
Fig. 3.5-4 shows an example of random access transmission method.
•
•
Chip synchronization with the target cell/sector is achieved.
The MS transmits RACH at a timing delayed at random from the frame timing it
received the common control channel. The random delay amount shall be one of
the 4 types of offset timing. The MS selects an offset timing at random for every
transmission of RACH.
•
When the BS detects an RACH whose CRC check result was OK, the BS shall be
able to transmit the PID by using the ACK mode of FACH at the next FACH
radio frame.
•
After transmitting RACH, if the PID value of the transmitted RACH cannot be
received by the ACK mode FACH after TRAmsec, the MS performs the
retransmission of RACH. The same PID value must be used for this. The
maximum number of retransmission times shall be NRA. The transmission
timing in case of retransmission shall be selected at random for every
RTT proposal of Japan
retransmission.

3.5.3 Power Control
Transmitter power control (TPC) is essential to a CDMA architecture to solve the nearfar problem and to increase system capacity. W-CDMA uses an adaptive TPC method
based upon desired signal level or Signal Interference Ratio (SIR).
3.5.3.1 Types of TPC
W-CDMA uses two TPC forms; SIR-based fast closed loop TPC and open loop TPC.
3.5.3.1.1 Open Loop TPC
Open loop TPC is used on channels that cannot apply closed loop TPC.
RACH uses open loop TPC..
For example,
•
The receiver estimates the transmission channel’s path loss. This is obtained by
calculating and averaging the path loss over a sufficient number of fading periods.
•
The transmitter power is calculated on the basis of the path loss, which is
estimated by the receiver of the transmitting station.

(1) Basic Operations
•
The received SIR measurement is carried out every transmitter power control
cycle (0.625ms) .
•
When the measured value is higher than the target SIR value, TPC bit =“0”.
When this is lower than the target SIR value, TPC bit=“1”. The receiving station
transmits TPC bit to the station whose transmitting power is controlled.
•
When TPC bit is received, soft decision on the TPC bits is performed. When the
value is judged as “0”, the transmitter power shall be reduced by 1dB, whereas if
it is judged as “1”, the transmitter power shall be raised by 1dB.
•
When the TPC bit cannot be received, the transmitter power value shall be kept at
a constant value. When SIR measurement cannot be performed, the TPC bit
shall always be =“1” .
(2) Uplink/Downlink Frame Timing
Fig 3.5-6 shows the transmitter power control timing. The frame timing of
uplink/downlink is shifted by fixed amount of time (within 1-slot), so that transmitter
power control with 1-slot control delay can be realized.

(3)Outer loop
The outer loop adjusts the closed-loop power control target SIR on basis of the quality
information. This function satisfies the required received quality (average FER, or
average BER).
3.5.3.2 Uplink Control
The transmitter power control procedures vary depending on the physical channel and
connecting mode.
3.5.3.2.1 Common Physical Channel
•
The transmitter power of RACH is decided by open loop transmitter power
control in the MS, and shall take a constant value within a radio frame.
•
Open loop TPC is based on received power level of the perch channel, whose
transmission level is broadcast on BCCH.
3.5.3.2.2 Dedicated Physical Channel
•
The initial transmitter power of DPCH is decided in a similar manner as RACH
by open loop transmitter power control. After this, the MS transit into SIR
based fast closed loop transmitter power control mode, and the SIR comparison
result on BS is notified to the MS by TPC bits. The MS performs relative
control of the transmitter power based on the TPC bits.
•
In order to satisfy the required received quality, an outer loop function is used to
update the target SIR value depending on the received quality
3.5.3.2.3 Transmitter Power Control upon Diversity Handover
As similar to the case without diversity handover, each BS measures the uplink
RTT proposal of Japan
received SIR, and transmits the TPC bit to the MS.
The MS receives the TPC bits independently from all connecting BS units. If there is
even one “0” among the soft decision result of TPC bits, the transmitter power shall be
reduced by 1dB. If the TPC bits are all “1”, the transmitter power shall be raised by
1dB.
3.5.3.3 Downlink Control
The transmitter power control procedures vary depending on the physical channel.
3.5.3.3.1 Perch Channel
All symbols other than the search code symbols are transmitted at a constant power.
The search code symbols are transmitted at a different power from that of other symbols.
The transmitter power is determined by the system and informed to the BS.
3.5.3.3.2 Common Physical Channel
In case that the MSs receive only one message from the BS, for example on the Paging
channel, the transmitter power is determined by the system and informed to the BS.
In case that a sequence of message exchange between a BS and a MS takes place, the
BS adjusts the transmitter power by open loop TPC based on the quality information
included in the uplink. The transmitter power is adjusted message by message. The
BS informs the transmit level to the MS, so that the MS can adjust its transmitter power.
3.5.3.3.3 Dedicated Physical Channel
The initial transmitter power is determined based on the signal quality information
during link establishment. After this initial transmission, the BS transits into SIR
based fast closed loop control with outer loop that adjusts the target SIR.

Multiple/Variable Rate Transmission
3.5.4.1 Variable Rate Transmission
3.5.4.1.1 Downlink
z
The timing that each variable rate DCH is multiplexed on a physical channel is
determined by Layer-3 negotiation based on the case of the highest data rate. The
head bit position of each variable rate DCH is fixed during changes of the data
rates.
z Rate matching is always performed using a common rule, which assumes that all
variable rate DCHs are of the highest data rate.
Discontinuous transmission according to the data rate is applied for downlinkDPDCH.
Rate detection is performed either by the use of a blind rate detection with CRC
or by the use of explicit rate information (RI). Independent blind rate detection
can be performed for each variable rate DCH. (The rate detection scheme
(blind detection or RI) of each variable rate DCH can be selected
independently according to the required service quality.)
3.5.4.1.2 Uplink
variable The transmission order of the variable rate DCH and its mapping are
determined by Layer-3 negotiation in advance.
Rate matching is performed frame by frame.
Continuous transmission is always applied for uplink-DPDCH. The modulated
BPSK symbol sequence is multiplied by power coefficient (this is necessary to
reduce the transmit power for lower rates).
Rate detection is performed either by the use of a blind rate detection, or by the
use of explicit rate information (RI). RI can be used for all variable rate DCH.
Blind rate detection can be used for primary rate DCH.
3.5.4.2 Multicode Transmission
3.5.4.2.1 Downlink
z
When one radio link consists of multiple dedicated physical channels (spreading
codes), transmission shall be performed as described below, and pilot aided
coherent detection and transmitter power control, etc. shall be performed
comprehensively for all the dedicated physical channels in one radio link. When
multiple radio links were allocated for one MS, pilot aided coherent detection and
transmitter power control shall be performed independently for each radio link.
RTT proposal of Japan

The frame timing and scrambling code phase shall be matched among all dedicated
physical channels in one radio link. Also, the symbol rate of the multiple physical
channels designated within one radio link shall all be the same.
In all of the dedicated physical channels within one radio link, the spreading code
used at one particular dedicated physical channel shall be used only for the pilot
symbol and the TPC symbol part. (See Fig. 3.5-7)
The transmission power of pilot symbols and TPC symbols in one radio link can be
different from the total combined power of all dedicated channels in that radio
link.(See Fig.3.5-8).
There is no rules on the difference of transmission power.
The Mobile Station should reflect the difference in target received SIR for

The synchronization establishment procedures upon intra-sector diversity handover is
basically the same as that of inter-cell diversity handover.
3.5.5.2 Diversity Handover (inter-cell)
At the start of diversity handover, the uplink dedicated physical channel transmitted
by the MS, and the downlink dedicated physical channel transmitted by the diversity
handover source BS will have their radio frame number and scrambling code phase
counted up continuously as usual, and they will not change at all. Naturally, the
continuity of the user information mounted on them will also be guaranteed, and will
not cause any interruption.
The synchronization establishment flow upon inter-cell diversity handover is described
in Fig. 3.5-9.
(a) The MS measures the frame time difference of the radio frame at the same frame
number between the uplink dedicated physical channel and the perch channel
transmitted at the handover destination BS. These measurements shall be notified
to the network. The measured value is the time difference of the frame timing of
the uplink dedicated physical channel against the frame timing of the perch
channel. The values shall always be positive values in chip units, and the range
shall be 0 ∼“uplink scrambling code cycle-1” chip.
(b) The MS notifies the frame time difference measurement values as layer 3 signals
to the BSC via the diversity handover source BS with the DCH for DCCH of the
uplink dedicated physical channel.
(c) The BSC notifies the frame time difference measurement result, together with
the frame offset and slot offset set up upon originating/ terminating call connection,
to the diversity handover destination BS with layer 3 signals. Furthermore, the
BSC notifies radio parameters such as the spreading codes used at the handover
destination BS etc., to the MS via the handover source BS.
(d) The MS starts the chip synchronization establishment process of downlink
channel from the handover destination BS with the notified radio parameters. The
RTT proposal of Japan
uplink channels being transmitted shall continue transmission without any
operations performed.
(e) The handover destination BS receives the notification of the above frame time
difference frame offset, and slot offset. Utilising these information, the BS starts
the transmission of downlink dedicated physical channels and starts the
sychronization establishment process of uplink dedicated physical channel
transmitted by the MS. As soon as chip synchronization and frame
synchronization using SW are established, hard-wired transmission shall be started.
(f) Based on the handover destination perch channel reception timing, the MS
establishes chip synchronization of downlink channel from handover destination
BS. As soon as chip synchronization is established, maximal ratio combining with
the downlink channel from handover source BS shall be started.

3.5.5.3 Inter-Frequency Handover
A key requirement for supporting a seamless inter-frequency handover is to allow the
possibility for the mobile station to carry out cell search on a carrier frequency
different from the current one, without affecting the ordinary data flow. The FDD
mode supports inter-frequency cell search with a Compressed Mode scheme. In the
compressed mode, slot Nfirst to Nlast are idle slots with pilot symbols and TPC
transmitted at the start of the first slot. There are two methods to fit the coded
information frame into a compressed radio frame.
• Code puncturing: This is done automatically in the rate-matching unit of downlink
Physical Channel Mapping Unit. Code puncturing is applied when the number of idle
slots is small.
• Changing to a rate ½ code: This is done when there are large number of idle slots.
The details of the Compressed Mode, e.g. the value of the parameters Nfirst, Nlast and
the number of frames compressed are for future study.
3.5.6 Packet Data Transmission Procedures
3.5.6.1 Adaptive Physical Channel Switching
To make good use of Radio Resources and Facilities Resources without service quality
degradation, it is necessary to switch physical channels (logical channels) on demand
depending on the transmission characteristics, such as packet data traffic.
Light Traffic in both Unlink and Downlink:
Common physical channel (FACH, RACH)
Heavy Traffic in each or both of Uplink and Downlink:
Dedicated Physical Channel (DCH for UPCH)
3.5.6.1.1 Judgement for Physical Channel Switching
The judgment is done at the network side according to the following factors.
Factor 1: Result of the transmission characteristics observation at the network side
Factor 2: In-Band or Out-Band information based on the result of transmission
characteristic observation at MS
3.5.6.1.2 Procedure for Control of Physical Channel Switching
Figure 3.5-10 shows the state transition diagram of physical channel switching.
Figure 3.5-11 shows examples of switching sequence between different states.
Control informations between MS and BS are Layer 3 informations.
Traffic control between MS and BS is necessary to prevent packet data from omission
RTT proposal of Japan
or overlapping when the switching is done.
Procedure for synchronization establishment of dedicated physical channel when
dedicated physical channel is switched over from common physical channel is as same
as normal synchronization establishment process when a call establish.
When there is no packet data to be transmitted during the process of synchronization
establishment of dedicated physical channels, transmission stop control (described later)
will start just after other station’s normal transmission is detected.

3.5.6.2 DTX Control for Dedicated Physical Channel (UPCH)
Dedicated physical channel (DCH for UPCH) can be kept for a certain period without
switching into common physical channel, even if there is no packet data to be
transmitted. During this reservation period, transmission of not only DPDCH but also
DPCCH can be suspended, in order not to waste capacity. Details of the transmission
control procedure are described below.
If there is control information or user information to be transmitted, transmission of
DPDCH in dedicated physical channel is set ‘ON’. If there is no information, it is set
‘OFF’.
As to DPCCH in dedicated physical channel, each control procedure in BS or MS is as
follows.
3.5.6.2.1 DPCCH Transmission Stop Control
BS Control Procedure
The necessity of transmission is judged for each radio frame. DPCCH transmission
will be stopped when both Condition 1 and 2 are satisfied during the transmission of
RTT proposal of Japan
DPCCH.
BS continues to transmit DPCCH and stop DPDCH, as far as both Condition 1 and 2 are
satisfied, even if there is no control information or user information to be transmitted.
Condition 1: More than Fkp-b radio frames have passed after the consumption
of control information and user information.
Condition 2: More than FcRc-b radio frames are detected continuously as CRC
NG in the uplink.
MS Control Procedure
The necessity of transmission is judged for each radio frame. DPCCH transmission
will be stopped when both Condition 3 and 4 are satisfied when DPCCH is transmitted.
MS continues to transmit DPCCH and stop DPDCH transmission, as far as both
Conditions 3 and 4 are satisfied, even if there is no control information or user
information to be transmitted.
Condition 3: More than Fkp-b radio frames have passed after the consumption
of control information and user information.
Condition 4: State of out of synchronization in downlink.
3.5.6.3 Handover Procedure for Packet Data Transmission
3.5.6.3.1 Handover for Change of Transmission Rate of Physical Channel
This handover is applied to dedicated physical channel (_ DCH for UPCH).
If maximum transmission rate of the dedicated physical channel which has already been
established is not suitable for traffic amount to be transmitted, the physical channel
should be switched over to a channel that has appropriate maximum transmission rate
using this handover procedure.
This handover procedure can be applied to uplink or downlink independently. Waste
of downlink spreading codes can be prevented by this handover mechanism.
The procedures of this handover are the same as normal intra-cell hard-handover.
3.5.6.3.2 Inter-Sector, Intra-Cell Handover
The same intra-cell diversity handover procedure as that for circuit switched mode is
applied to dedicated physical channel (DCH for UPCH).
Hard handover is applied to common physical channel (FACH, RACH).
3.5.6.3.3_ Inter-Cell Handover
Ether Diversity handover or Hard handover can be applied to dedicated physical
channel. Appropriate handover procedure can be used depending on difference of
propagation losses between MS and several BSs.
Hard handover is applied to common physical channel (FACH, RACH).
RTT proposal of Japan
4. System Description for TDD mode
4.1 TDD Operation
In the TDD mode, both uplink and downlink use the same frequency band, see Fig. 4.1-1. The
intention for this is to keep the TDD mode as much similar to the FDD mode as possible, in order
to facilitate easy implementation of dual mode FDD/TDD phones as well as to facilitate the reuse
of IC’s in single mode TDD phones. The control channel multiplexing and uplink/downlink
spreading codes are therefore the same in TDD mode as in FDD mode. The TDD mode shares all
key features of W-CDMA, such as a high degree of service flexibility.
As TDD uses the same frequency band for both uplink and downlink, the fading patterns are
highly correlated. This in turn facilitates several techniques to be used for mitigating multi-path
fading, such as power control and transmit antenna diversity.

The channel structure for both logical and physical channels in the TDD mode are the same as that
of FDD mode.

4.3 Frame Format
For TDD mode, all physical channels also take a three-layered structure consisting of superframes,
radio frames, and time slots. Depending on the physical channel and symbol rate, the
configuration of radio frames or time slots differ from one another. All physical channels need
guard symbols in every time slot. The time slots are used in terms of a TDMA component to
separate different user signals in the time and the code domain. The physical channel signal
format is presented in Fig.4.3-1.

Perch channel is transmitted only on the downlink time slots. For TDD mode, common pilot and
search code of the perch channel are time multiplexed in the middle of downlink time slot.
Therefore, data symbols, which are also time multiplexed, are divided into 2 parts.

Dedicated physical channel is only transmitted on the assigned time slots. Dedicated physical
channel is flexibly allocated in uplink and downlink time slots. The same time slot allocation is
needed for all base station within the whole area of synchronization. Spreading factor of
scrambling code and the number of codes for multi-code transmission are assigned independently
for uplink and downlink. The DPDCH and DPCCH are time multiplexed within each radio frame
and transmitted with QPSK modulation.

4.4 Flexible UL/DL Time-slot Allocation
In TDD mode, each 10 ms-frame consists of 16 time-slots, each allocated to either uplink or
downlink.
A flexible time-slot allocation, where time slots can be arbitrarily allocated to uplink and downlink
except for the first time slot of downlink, is adopted for the TDD mode as shown in Fig.4.4-1.
Such flexible allocation can improve the capabilities of the TDD mode to operate in an
uncoordinated environment. Obviously, the same timeslot allocation is needed for all base station
within the whole area of synchronization.
RTT proposal of Japan
10 ms
Fig. 4.4-1 UL/DL allocation for TDD mode
Basically, a symmetric uplink/downlink allocation with multiple-switching-point configuration
shown in Fig.4.4-2 is used. Perch channel and common control channel are assigned to all time
slots of downlink. For asymmetric UL/DL capacity allocation, an asymmetric time slot allocation
can be used. As an example, an asymmetric allocation with multiple switching-points is shown in
Fig.4.4-3 and an asymmetric allocation with a single switching-point is shown in Fig.4.4-4. The
multiple-switching-point configuration is obviously best from the viewpoint of fast (open-loop or
closed-loop) power control.
Furthermore, in the case of the multiple-switching-point
configuration shown in Fig.4.4-3, the same allocation and mapping scheme for perch channels and
common control channels can be used as a symmetric mode.

The following channel coding and radio resource functions are described on the assumption that
the allocation shown in Fig.4.4-2 is used and all time slots with the same direction are assigned for
each channel. The allocation used for all time slots is obviously best from the perspective of
interleaving gain, lower peak-power and coverage efficiency.
RTT proposal of Japan
4.5 Channel Coding and Service Multiplexing
4.5.1 Channel Coding
Two types of forward-error-correction (FEC) coding schemes, convolutional codes and turbo
codes, are adopted to obtain efficient coding gains under various environments as similar to the
FDD mode.
Convolutional codes of rate 1/3 are mainly used for low-bit-rate traffic channels and of rate 1/2
are used for control channels. A constraint length of 9 is used for both coding rates. Turbo
code is employed for high-rate data transmissions. The coding rate of turbo code is 1/3 or 1/2
and constraint length is 3. The channel coding procedures for the TDD mode are the same as
those for the FDD mode shown in Fig.3.3-2 and Fig.3.3-3.
4.5.2 Service Multiplexing
The procedure for service multiplexing is the same as that for FDD mode.
4.5.3 Service Examples
The general channel coding and service multiplexing procedures are almost the same as those for
the FDD mode. The physical channel mapping units for single-code and multi-code transmission
that are different from the FDD mode are shown in Fig.4.5-1 and Fig.4.5-2.

For TDD mode, both uplink and downlink spreading codes are the same as those for the FDD
mode. Orthogonal Variable Spreading Factor (OVSF) codes are employed for the spreading
codes in both links. Furthermore, the Special Pilot Scrambling Codes (PSC) for joint channel
estimation of active users in time slots can be applied as an option. The PSC for each user is
generated from one basic code. The modulation is QPSK with time-multiplexed DPDCH and
DPCCH in both uplink and downlink (see Fig.3.4-1). The pulse shaping filters are root-raised
cosine (RRC) with a roll-off factor of 0.22 as similar to the FDD mode.
4.7 Radio Resource Functions
Random access procedure is the same as the FDD mode.
4.7.1 Initial Cell Search
For TDD mode, smooth and fast cell acquisition can be realized by the specific structure of the
perch channel as similar to the FDD mode. Like the FDD mode, a fast cell search scheme using
three step cell search method is adopted. The basic scheme is almost the same as the inter-cell
asynchronous operation of the FDD mode, because the structure of the search code symbols is the
same. The difference in this process is the spreading factor for the 1st search code (1st SC) and
2nd search code (2nd SC), which is 128 instead of 256. At the same time, the scrambling code
phase does not coincide with the frame phase as shown in Fig.4.7-1, which is also different from
the FDD mode. Therefore, one more step is added to the FDD mode for the cell search scheme
of TDD. After identifying the scrambling code timing and scrambling code group from 2nd search
code, scrambling code detection and frame synchronization processes are performed in parallel.
During this step, frame synchronization can be detected by using the SW (Sync. Word) of pilot
symbols.

4.7.2 Inter-cell Synchronization Requirement
For TDD operation, inter-cell synchronization is required. All frame timings among neighboring
BSs need to match with one another. Several concepts can be used to realize this as shown, for
example, in Fig.4.7-2. The highest level of synchronization can be implemented by using GPS as
an external system reference. It is also possible to use GPS only for the initial adjustment of
system clock, and the synchronization can be maintained through the wire-line network.
Therefore, by combining the use of a wire-line network, the dependence on GPS can be minimized.
The requirement for inter-cell synchronization accuracy is not severe (within the order of several
micro-seconds). There is also another option to implement synchronization without relying on
GPS. This option is mainly based on synchronization by the monitoring of the radio interface.
Below shows one example on how to realize this concept. A master BS is located in a sub-area.
It is synchronized with the wire-line network. All slave BSs that belong to the master BS receive
the signal from the master BS, so that they can achieve synchronization. After this, a slave BS
transmits signals to the master BS. The master BS receives the signal from the slave BS and
measures the propagation delay. Then, the master BS transmits the propagation delay
information. Therefore, the slave BS can adjust the system clock and maintain it by deriving the
reference clock from the wire-line network. Then the system clock of the master BS has to be
synchronized to the clock of the wire-line network.

4.7.3 Power Control
Power control for perch channel is the same as the FDD mode.
RTT proposal of Japan
For the uplink physical channel for common control, transmission power of the perch channel and
the uplink interference power are transmitted using BCCH. Mobile station decides the
transmission power of RACH by open-loop power control based on the information and the signal
power level of the perch channel. Power control for the downlink physical channel for common
control is same as the FDD mode.
4.7.3.1 Uplink Power Control for Dedicated Physical Channel
The initial transmission power is decided in a similar manner as RACH.
After the
synchronization between BS and MS is established, MS transits into a combination scheme of
open-loop and fast closed-loop transmitter power control (TPC). Fast closed-loop TPC is based
on SIR, and the TPC processing procedures are the same as the FDD mode. During this power
control process, the BS periodically makes a comparison between the received SIR measurement
value and the target SIR value. When the measured value is higher than the target SIR, TPC bit
= “0”. When this is lower than the target SIR value, TPC bit = “1”. The TPC bits shall be
transmitted continuously to the MS. At the MS, soft decision on the TPC bits is performed, and
when it is judged as “0”, the target received power at the BS (P BS) shall be reduced by P TPCdB,
whereas if it is judged as “1”, P BS shall be raised by PTPCdB.
The MS measures the received
signal power of the perch channel, which is code multiplexed with the dedicated channel, at the
previous downlink time slot. For example, this is done at each downlink timeslot in Fig. 4.4-2.
After this, the transmitter power is decided by the combination of open-loop and closed-loop
transmitter power control based on the equation below:
TMS = (TBS + PTPC ) + (PBS – RMS)
TMS: Transmission power of MS
TBS: Estimated transmission power of Perch channel on BS
PBS: Target received power on BS
RMS: Received power of Perch channel on MS
When the TPC bit cannot be received due to out-of-synchronization, PBS shall be kept at a
constant value. When SIR measurement cannot be performed for being out-of-synchronization,
the TPC bit shall always be = “1” during the period of being out-of-synchronization.
The outer loop scheme that satisfies the required reception quality is applied to closed-loop control
as similar to the FDD mode.
Fig.4.7-3 shows uplink transmitter power control timing for the case of symmetric allocation
shown in Fig.4.4-2. A combination of open-loop power control with 1-slot control delay and
RTT proposal of Japan
closed-loop with 2-slots control delay can be realized.

4.7.3.2 Downlink Power Control for Dedicated Physical Channel
In principle, there is no restrictions on the initial transmission power of the downlink Dedicated
Physical Channel. After the initial transmission, the BS transits into SIR-based fast closed-loop
TPC as similar to the FDD mode.
The measurement of received SIR shall be carried out periodically at the MS. When the
measured value is higher than the target SIR value, TPC bit = “0”. When this is lower than the
target SIR value, TPC bit = “1”. 2bits are transmitted continuously to the BS. At the BS, soft
decision on the TPC bits is performed, and when it is judged as “0”, the transmission power shall
be reduced by PTPCdB, whereas if it is judged as “1”, the transmission power shall be raised by
PTPCdB.
When the TPC bit cannot be received due to out-of-synchronization, the transmission power value
shall be kept at a constant value. When SIR measurement cannot be performed due to out-ofsynchronization, the TPC bit shall always be = “1” during the period of being out-ofsynchronization.
The outer loop scheme that satisfies the required reception quality is applied to closed-loop control
as the FDD mode.
Fig.4.7-4 shows downlink transmitter power control timing for the case of symmetric allocation
shown in Fig.4.4-2. A closed-loop transmitter power control with 2-slots control delay can be
realized.

4.7.5 Handover
Three types of handover, diversity handover, hard handover and inter-frequency handover, are
supported for the TDD mode as similar to the FDD mode.
4.7.5.1 Diversity Handover
(1) Intra-cell
The procedures and maximum number of sectors for intra-cell diversity handover
RTT proposal of Japan
are the same
as those for the FDD mode.
For uplink, maximal ratio combining is performed on all symbols of the physical channel. Uplink
transmitter power control is performed at mobile station after maximal ratio combining.
Downlink transmitter power control is performed by using TPC symbol. The procedures in the
wired transmission part are the same as the FDD mode.
For Downlink, same symbols are transmitted from all sector antennas. The procedures for the
wired transmission part are the same as the FDD mode.
(2) Inter-cell
The procedures for inter-cell diversity handover is the same as the FDD mode.
4.7.5.2 Hard Handover
The same hard handover procedures as the FDD mode are applied to the TDD mode as well.
4.7.5.3 Inter-frequency Handover
A key requirement for supporting a seamless inter-frequency handover is to allow the possibility
for the mobile station to carry out cell search on a carrier frequency different from the current one,
without affecting the ordinary data flow. The TDD mode supports inter-frequency cell search
with two different compressed modes; the basic measurement mode approach and the slotteddownlink-transmission mode (slotted mode) approach. The TDD mode can flexibly allocate time
slots for each dedicated physical channel. Therefore, if a small number of slots are usually
assigned for idle slots, the basic measurement mode is not needed, and if a large number of slots is
usually assigned for idle slots, slotted mode is also not required for inter-frequency handover.
4.7.5.3.1 Basic Measurement Mode
The mobile stations initially perform power measurements on target carriers. This requires only a
limited amount of time and can be performed by a single receiver terminal if a small number of
slots, e.g. one uplink and one downlink slot for a specific link, are available. Like the FDD
mode, code puncturing is used to achieve this. As an option, it is possible to increase the
transmitted power in order to compensate for puncturing. Measurements that are made after the
despreading process have to rely on the use of the slotted mode on the downlink, if only one
receiver unit is used.
4.7.5.3.2 Slotted Mode
The principle of the slotted downlink transmission approach is illustrated in Fig.4.7-7. When the
slotted mode is performed, the information normally transmitted during a 10 ms frame is
compressed in time, either by code puncturing or by changing the coding rate R=1/3 into R=1/2
RTT proposal of Japan
as similar to the FDD mode. In this way, a large number of slots are created, during which the
mobile-station receiver is idle and can be used for inter-frequency measurements. Note that the
idle slot is created without any loss of data as the number of information bits per frame is kept
constant, while the processing gain is reduced by either reducing the spreading factor or increasing
the coding rate. As illustrated in Fig.4.7-7, the momentary transmitter power is increased in the
slotted frame in order to keep the quality (BER, FER, etc.) unaffected by the reduced processing
gain.

4.7.6 Downlink Transmit Diversity
Transmit diversity in the downlink provides means to achieve similar performance gains as the
mobile-station receiver diversity without the complexity of a second mobile-station receiver.
Furthermore, transmit diversity improves the SIR and increases the system capacity. Depending on
the mobile station’s distance to the base station, its speed, and the asymmetry ratio, selective
transmit diversity (STD) or parallel transmit diversity (PTD) can be employed. These techniques
are described herewith.
With STD, the received signal power of uplink is measured for each of the antennas at the BS over
every single uplink interval (1 slot). The antenna with the highest signal level is used to transmit
the downlink information for that link during the next interval over which the carrier is used for
the downlink (1 or more slots). The basis for the gains from this type of diversity is the
availability of information on the channel due to the use of the same frequency for uplink and
downlink. STD is applied only to dedicated physical channels.
For perch channel and common physical channels such as PCH, PTD can be applied optionally.
PTD can be implemented as follows. Coded bits are copied into two data streams in parallel and
transmitted via two separate antennas each with half power. Different orthogonal spreading
codes are used for each antenna. This maintains the orthogonality between the two output
streams, and hence self-interference is negligible. The introduction of PTD can improve the
received performance of the downlink due to diversity gains. Furthermore, it can improve the
RTT proposal of Japan
uplink performance of the dedicated channel. Open-loop transmitter power control can be
controlled by using the combing received power of perch channel from both antennas with
different spreading codes. The structure mentioned above is highly flexible. It may be easily
extended to more antennas (3,4, etc.). PTD may be an optional feature that can be turned on
only when needed. There is little additional processing required for PTD at the mobile station.
4.7.7 Packet Data Transmission Procedures
Packet data transmission using the dedicated physical channels is always handled as a pair of
uplink and downlink as similar to the FDD mode.
The procedures for physical channel switching, DTX control and handover are the same as the
FDD mode.
4.7.7.1 Transmitter power control for Packet Data Transmission
• Uplink common physical channel (RACH):
Open-loop transmitter power control is adopted.
• Downlink common physical channel (FACH):
Transmission power is determined by the information transmitted on RACH, or fixed
power.
• Uplink dedicated physical channel (UPCH):
Open-loop transmitter power control is applied basically. Fast closed-loop transmitter
power control is combined with open loop control. TPC bits in downlink dedicated
physical channel (UPCH) are used for power control.
• Downlink dedicated physical channel (UPCH):
Fast closed-loop transmitter power control is adopted. TPC bits in the uplink dedicated
physical channel (UPCH) are used.
RTT proposal of Japan
5. Performance Enhancing Features
There exist a number of ways to enhance the performance of the W-CDMA system. In general it
is easy in a CDMA system to achieve immediate quality, coverage, and capacity gains directly
from link improvements. This is due to single-cell reuse and also to the fact that power is the
only shared resource. In this section, a number of examples of performance enhancing features,
currently not seen as parts of the ARIB W-CDMA concept, are described. The ARIB
specification is written in such a way that these enhancing features can be added to its thirdgeneration mobile communications system specifications at a later stage.
5.1 Adaptive Antennas
Adaptive antennas are recognized as a way to enhance capacity and coverage of the system.
Solutions employing adaptive antennas are already supported in the W-CDMA concept through
the use of connection-dedicated pilot bits on both uplink and downlink. In addition, adaptive
antenna considerations have been included in the design of the downlink common physical
channels.
5.2 Interference Canceller
The W-CDMA technology is designed to work without requiring receivers for interference
cancellation.. However, it is recognized that the use of an interference canceller can provide
capacity gains.
5.3 Downlink Diversity
Receiver diversity in the mobile station is not required in the concept. However, since receiver
diversity gives a gain of around 3 dB in performance, it can be employed in the terminal for better
quality and system capacity. Receiver diversity is likely to be implemented, especially in data
terminals such as PDAs and portable PCs.
Transmit diversity is available not only for TDD mode but also for FDD mode in the W-CDMA
concept. BS antenna can be selected by the antenna selection information fed back from the
mobile station, which identifies the best BS antenna by measuring the received quality of antenna
specific signals. For this purpose, some TPC bits in uplink can be stolen by the bits bearing
antenna selection information. This antenna selection mechanism can alternatively be used for
site selection in instantaneous hard-handover, which offers the potential to increase capacity over
diversity handover in low mobility cases,
RTT proposal of Japan
5.4 Optimized Uplink Pilot Power
With the current uplink scheme, the uplink pilot power is constant for all rates within a variablerate connection. By including additional variable-strength pilot-bits on the I-branch, the uplink
pilot power could be optimized for each rate within the rate set of a variable-rate connection.
5.5 Positioning Function
Various positioning methods for location services are developed such as AOA (Angle of Arrival),
TOA (Time of Arrival), TDOA (Time Difference of Arrival), Combined positioning techniques.
The W-CDMA technology can employ any positioning methods. The wideband nature of the
proposed RTT enables positioning with high accuracy.

System Flexibility
6.1 FWA Applications
The proposed RTT can be applied to FWA systems.
General objectives and requirements of FWA are:
To reduce cost per FWA subscriber by minimizing FWA optional parts of
radio interface;
2) To provide, in both urban and rural areas, economical services of high
quality and integrity comparable to those of the fixed public network.
The proposed RTT is designed to meet these objectives and requirements.
Moreover, FWA based on the proposed RTT has the following features.
6.1.1 Services on FWA
FWA systems have to provide services with the same quality as that of the conventional
wired systems, a. voice quality that is equal to or
better than that for the existing wired-line system. It is also desirable that
more reliable data transmission is supported by FWA than that of
mobile systems. The proposed RTT supports these requirements for FWA
application.
Also
it
has
capability
to
provide
QoS
compatible with ISDN. The CDMA architecture allows QoS to be flexibly and
dynamically controlled, so that the FWA of the proposed RTT can offer a variety of
services.
6.1.2 Common Radio Interface with Mobile System
The same radio interface designed for mobile application is applied to FWA
application.
It is not necessary to modify the configuration of
base stations of the proposed RTT for FWA, which is helpful
in
realizing
systems
efficiently
and
economically.
Also
major
components of terminals are designed and used commonly for both mobile and FWA
systems.
6.1.3 Extension of Cell Size

of the proposed RTT. It extends the maximum cell radius. Also, traffic
capacity of CDMA systems is anticipated to increase owing to reduction of inter-cell
interference when a directional antenna is applied. Therefore, FWA of
the proposed RTT can be a highly competitive replacement for landline
voice systems.
6.2 Spectrum Sharing
6.2.1 Overlay of Multiple Cells
In order to offer high traffic capacity in the proposed RTT with minimal handovers for
mobile
stations
at
various
speeds,
while
maximizing
spectral
efficiency, the proposed RTT has different cell types in terms of the mobile and
base station parameters, such as cell size, mobility characteristics, output power
and types of services utilized. In principle, it is possible to operate these different
cell types simultaneously in the same geographical area. All cells in the cell layer
are fully or partly sharing the same spectrum resource.
6.2.2 Flexibility of Spectrum Utilization and Overlay of Spectra with
different Bandwidth
The
proposed
RTT
offers
various
types
of
bandwidths corresponding to chip rates ranging from 1.024 to 16.384
Mcps.
. The combination of these bandwidths allows various ways of
using
the
spectrum
in
the
overall
available
bandwidth,
which.may differ from one region to another.. .
Guard banding and interference characteristics of the proposed RTT permit operation in
a 5MHz spectrum allocation.
Moreover, spectrum overlay of these various bandwidths can be used without
imposing any technical difficulties to the systems based on the proposed RTT.
6.3 Interoperability
6.3.1 Easiness of Dual-mode Terminal Implementation
6.3.1.1 Dual-mode Terminals for FDD and TDD modes
The proposed RTT has two operation modes, i.e., FDD and TDD, as described in
chapter
2.4.
As
stated
in
the
above-mentioned
chapter, the essential parameters of the two modes are almost common. Consequently,
RTT proposal of Japan
most of RF and baseband circuits in the mobile terminal can be shared
by the two operation modes. This contributes to realizing small and light-weight dual
mode terminals for FDD and TDD modes.
6.3.1.2 Dual-mode Terminals for 2G and 3G Systems
The proposed RTT was designed taking into account the feasibility of dualmode terminals with typical second-generation systems, e.g., PDC, GSM and IS95. Systems based on the proposed RTT can support most services provided
by second-generation systems, in addition to IMT-2000 services.
6.3.2 Inter-system Handover
The proposed RTT has inherent capability for inter-system handover based on
compressed mode transmission. . Handover between FDD mode and TDD mode or
between the proposed RTT and any other mobile systems such as the second-generation
systems can be realized by means of this technology.

A1.1.3
Does the RTT include any features in support of FWA
application? Provide detail about the impact of those
features on the technical parameters provided in this
template, stating whether the technical parameters
provided apply for mobile as well as for FWA
applications.
The concept can be applied to FWA applications.
The proposed RTT provides the same or higher
quality and capacity of FWA services as/than that
of the mobile services without any system or
hardware impact.
Complexity of terminals is reducible because some
functions, which are indispensable for mobile
terminals such as handover capability, fast power
control, etc., can be cut down for FWA
applications. System capacity can be increased
since there is no terminal connected to multiple base
stations by handover. Moreover, service area can
be extended by use of a directional antenna in the
terminal side.
A1.2
Technical parameters
NOTE 1 – Parameters for both forward link and reverse link should be described separately, if necessary.
A1.2.1
What is the minimum frequency band required to
deploy the system (MHz)?
5MHz
This is the minimum frequency band required to
deploy the system but wider frequency bandwidth
is recommended for more efficient operation.
The proposed RTT can offer its full capability
efficiently if 20MHz bandwidth is allocated.
A1.2.2
What is the duplex method: TDD or FDD?
Both FDD and TDD modes are specified.
A1.2.2.1
What is the minimum up/down frequency separation for
FDD?
Depends on system frequency bandwidth to be
deployed. 80MHz is a sufficient value for the case
of 60MHz bandwidth which is expected to be the
size of one total contiguous bandwidth in FDD
paired band.
A1.2.2.2
What is requirement of transmit/receive isolation? Does
the proposal require a duplexer in either the mobile
station (MS) or BS?
FDD mode: Duplexer needed.
Transmit/receive isolation: Required isolation is
no more than 60dB.
TDD mode: No duplexer needed
A1.2.3
Does the RTT allow asymmetric transmission to use the
available spectrum? Characterize.
The possibility for a large range of uplink/downlink
asymmetry on the connection level follows from the
possibility of independent setting of uplink and
downlink bearer-service characteristics ( rate,
delay, bit-error-rate etc. ).
The possibility for uplink/downlink asymmetry on
the cell-level is due to the use of one-cell reuse,
where downlink and uplink resources can be moved
independently from each other between
neighbouring cells.
Asymmetry on a total-system level can be achieved
with the proposed TDD mode where the total
available time can be asymmetrically allocated to
the uplink/downlink. For the FDD mode, totalsystem asymmetry is possible as long as more
bandwidth is allocated to downlink than uplink or
vice versa.

Describe the approach taken for the receivers (MS and

A RAKE receiver (or more advanced multi-user

gains.
Path/Antenna/site diversity
A1.2.14.1
Describe the robustness to intersymbol interference and
the specific delay spread profiles that are best or worst
for the proposal.
The theoretical upper-limit of tolerable time
dispersion is dependent on the scrambling code
length. It is 10£(2££ 16) ms for uplink and 10ms
for downlink. In practice, the limit of time
dispersion is dependent on the implementation of
the searcher window size, which should be more
than the maximum excess delay to be experienced
in various typical operation environments.
Within the limit, the size of the delay spread does
not, in itself, have any impact on the performance.
On the other hand, the shape of the delay spread
profile may have an impact on the performance.
RAKE receiver efficiently captures signal energy
dispersed over the searcher window size and
provides multipath diversity gain. There may be a

Variations in path amplitudes/phases can be tracked
with pilot symbol assisted coherent detection. The
period of pilot symbols is 0.625 ms, and the
coherent detection can cope with variation of at
least 500Hz with almost no performance
degradation.
Long term variations in the path profile, e.g. the
occurrence of new paths can be detected by the
searcher. Update time of path profile is dependent
on searcher implementation, typically ranging from
10ms (on a frame-basis) to several 10s ms.
Typically, de-correlation length of the long-term
fading is 20m in vehicular environment, which
requires 288ms to travel at the speed of 250km/h.
Due to this fact, the above update period is
sufficient to track path profile changes to be
encountered in practice.

requirements?
The proposed RTT accommodates 128 data
channels with FDD and 64 data channels with TDD
per carrier for 4.096Mcps. The maximum number
of channels is limited by the number of the
orthogonal spreading codes for the downlink
channel. Note that the number of actual
communication channels depends on the
environments and conditions.
A1.2.18
Variable bit rate capabilities : describe the ways the
proposal is able to handle variable baseband
transmission rates. For example, does the RTT use:
}Adaptive source coding as a function of RF
quality is possible. Adaptive channel coding as a
function of RF signal quality is not needed due to
transmitter power control for maintaining received
power and/or BER/FER constant and CDMA
multi-rate scheme and spreading for providing
appropriate channel resources.

application?
–øVariable voice/data channel utilization as a
function of traffic mix requirements?
Characterize how the bit rate modification is performed.
In addition, what are the advantages of your system
proposal associated with variable bit rate capabilities?
}The proposed RTT allows for variable voice/data
channel utilization as a function of traffic mix
requirements.
Different channel bit rates are possible by changing
the spreading factor in factors of 2 from 256 down
to 4. For the highest rates, multi-code transmission,
i.e. transmission on several parallel code channels,
is used. An arbitrary user bit rate after channel
coding is matched to the closest possible channel bit
rate by code puncturing/repetition.
For variable-rate transmission, the rate can vary on
a 10ms basis. The proposed RTT has two modes to
discriminate transmitted data rate. One method is
that explicit rate information, to simplify decoding,
may be transmitted on a parallel control channel.
Another method is a blind rate detection using CRC
check.
Multiple variable services can be time multiplexed
on one variable-rate physical channel or code
multiplexed on different variable-rate physical
channels.
The advantage with this approach is that the bit rate
can be varied on a frame-by-frame basis without
any explicit resource allocation and negotiation.
It also for the independent quality control of each
service on a multi-service connection.
A1.2.18.1
What are the user information bit rates in each variable
bit rate mode?
RTT proposal of Japan
The user bit rate can be varied from 0-2048kbps.
For a given connection, a sub-set of these rates is
chosen at call set-up. During the call, the rate can be
varied between the rates within the sub-set on a
frame-by-frame basis. The sub-set of rates can also
be changed during a call, e.g. due to the
addition/removal of services.

rate, delay and BER/frame error rate (FER).
All of circuit-switched, packet switched and
asymmetric services are supported by the proposed
RTT.
All service classes can be supported with the

A1.2.20.1
For delay constrained, connection oriented (Class A).
The proposed RTT provides user bit rates up to
2Mbps. In addition, it supports high bit rate in
several steps being adopted by existing ISDN (n

- 64 kbps unrestricted data (B)
- 384 kbps unrestricted data (H0)
- 1536 kbps unrestricted data (H11)
- 1920 kbps unrestricted data (H12)
BER/FER depend on QOS of services, i.e., because

be set by controlling the amount of interference
according to QOS requirements.

Delay and BER/FER are flexibly set according to
the QOS requirements for them.
Whether a communication path is connection
oriented or connectionless is an issue in the higher
layer and was not determined in the discussion of
the proposed RTT.
FDD mode: The RTT uses SIR based closed-loop
power control on both uplink and down link. Open
loop power control is used for random access. The
use of fast power control significantly improves the
link-performance (BER as a function of Eb/N0)
especially in the case of a slow moving mobile
station.
TDD mode: Open-loop power control on uplink
based on the estimation of propagation loss from
downlink (BCCH) improves the degradation due to
fading.
And it's possible to decrease the control accuracy
and quality difference between channels by
combining with SIR based closed loop power
control.

Handover/automatic radio link transfer (ALT) : do the
radio transmission technologies support handover?
The proposed RTT supports two types of
automatic handovers.
Characterize the type of handover strategy (or
strategies) which may be supported, e.g. MS assisted
handover. Give explanations on potential advantages,
e.g. possible choice of handover algorithms. Provide
evidence whenever possible.
One handover scheme is based on a mobile assisted
diversity handover mechanism.
The mobile station (MS) monitors the pilot signal
levels received from neighboring base stations, and
reports to the network pilots crossing or above a
given set of dynamic thresholds. Based on this
information, the network orders the MS to add or
remove pilots from its Active Set.
The Active Set is defined as the set of base station
for which user signal is simultaneously demodulated
and coherently combined.
The same user information modulated by the
appropriate base station code is sent from multiple
base stations.
Coherent combining of the different signals from
different sectorized antennas, from different base
stations, or from the same antenna but on different
multiple path components is performed in the MS
by the usage of RAKE receivers.
The signal transmitted by a mobile station is
processed by base stations with which the mobile
station is in diversity handover. The received signal
from different sectors of a base station (cell) can be
combined in the base station, and the received
signal from different base stations (cells) can be
combined at the base station controller. Diversity
handover results in increased coverage range on the
uplink.
This diversity handover mechanism results in
seamless handover without any disruption of
service.
The spatial diversity obtained reduces the frame
error rate in the handover regions and allows for
improved performance in difficult
radio
environment.
Another handover mechanism is the so called hard
handover.
During hard handover, only one radio link is used
between a mobile station and a base station.
The radio link establishment procedure at the
destination base station uses the same procedure as
in originating a call.
Hard handover is used during packet transmission
over the common physical channel, and is also used
in changing transmission rate of physical channel
during packet transmission..
A1.2.24.1
What is the break duration (s) when a handover is
executed? In this evaluation, a detailed description of
the impact of the handover on the service performance
should also be given. Explain how the estimate was
derived.

ANNEX1
A1.2.24.2
Technologies Description Template
For the proposed RTT, can handover cope with rapid
decrease in signal strength (e.g. street corner effect)?
The MS continuously searches for signal from new
and existing BS.
Give a detailed description of:
It also maintains threshold based on current quality
of the downlink to add newly detected BS or to
drop existing BS from its diversity handover active
set.
–øthe way the handover detected, initiated and ø
øøexecuted,
The need to add or drop is sent in a message to the
system, which determines whether to execute
addition or deletion .
–øhow long each of this action lasts ø
øø(minimum/maximum time (ms)),
–
the time-out periods for these actions.
The time it takes to perform the above actions
depends on the MS and BS architecture.
There is no time-out period when diversity
handover is performed.

system deployment (e.g. necessity to add new cells
and/or new carriers) particularly in terms of frequency
planning.

channel allocation (DCA) schemes which may be
supported and characterize their impact on system
performance (e.g. in terms of adaptability to varying
interference conditions, adaptability to varying traffic
conditions, capability to avoid frequency planning,
impact on the reuse distance, etc.).
DCA not needed.
A1.2.28
Mixed cell architecture : how well does the RTT
accommodate mixed cell architectures (pico, micro and
macrocells)? Does the proposal provide pico, micro and
macro cell user service in a single licensed spectrum
assignment, with handoff as required between them?

NOTE 1 – Cell definitions are as follows:
– pico – cell hex radius: r ? 100 m
– micro: 100 m ? r ? 1 000 m
– macro: r ? 1 000 m.
The proposed RTT can provide pico-, micro-, and
macro-cells in one common frequency band or in
separate frequency bands. In the latter case, a total
of 2*15MHz(FDD mode) or 15MHz(TDD mode)
spectrum assignment is needed. In either case,
seamless handover is possible between the cell
layers.

The physical layer provides means for transmission
rate signalling which can be used also to indicate
which service is active, and thus the introduction of
an associated control channel with service
negotiation is supported by the proposed RTT.
A1.2.31
Does the RTT support a bandwidth on demand (BOD)
capability? BOD refers specifically to the ability of an
end-user to request multi-bearer services. Typically,
this is given as the capacity in the form of bits per
second of throughput. Multi-bearer services can be
implemented by using such technologies as multicarrier, multi-time slot or multi-codes. If so,
characterize these capabilities.
NOTE 1 – BOD does not refer to the self-adaptive
feature of the radio channel to cope with changes in the
transmission quality (see § A1.2.5.1).
Bandwidth on demand is supported with a
granularity of 100bps in the range from 100bps to
2.048Mbps channel rate. The bandwidth on
demand possibility is implemented by multiplexing
the multi-bearer traffic on a single L1 traffic stream
to be carried by the variable rate DPDCH resource,
which is for low and medium rates a variable
spreading factor single code channel, and for higher
rates a combination of variable spreading factor and
multi-code transmission.

What is the radio transmission processing delay due to
the overall process of channel coding, bit interleaving,
framing, etc., not including source coding? This is given
as transmitter delay from the input of the channel coder
to the antenna plus the receiver delay from the antenna
to the output of the channel decoder. Provide this

Description of the ability to sustain quality under certain extreme conditions.
RTT proposal of Japan
ANNEX1
Technologies Description Template
A1.3.9.1
System overload (terrestrial only) : characterize system
behaviour and performance in such conditions for each
test services in Annex 2, including potential impact on
adjacent cells. Describe the effect on system
performance in terms of blocking grade of service for
the cases that the load on a particular cell is 125%,
150%, 175%, and 200% of full load. Also describe the
effect of blocking on the immediate adjacent cells.
Voice service is to be considered here. Full load means a
traffic loading which results in 1% call blocking with the
BER of 1 ? 10–3 maintained.
Overload causes graceful degradation of system
performance. The techniques commonly referred to
as cell breathing can also be applied. i.e., when the
loading of a cell in a system is overloaded., the up
link interference is high and the effective range of
MS is reduced due to power constraints. If the
down link power is reduced accordingly then the
MS on the border will be naturally handed over to
the neighbouring cells, effectively reducing the
coverage of the overloaded cell and decreasing its
load without impacting the link performance.
A1.3.9.2
Hardware failures : characterize system behaviour and
performance in such conditions. Provide detailed
explanation on any calculation.
Implementation dependent.
A1.3.9.3
Interference immunity : characterize system immunity
or protection mechanisms against interference. What is
the interference detection method? What is the
interference avoidance method?

A1.4.4
Timing jitter : for BS (or LES) and MS give:
– the maximum jitter on the transmit signal,
–øthe maximum jitter tolerated on the received
signal.
Timing jitter is defined as r.m.s. value of the time
variance normalized by symbol duration.
RTT proposal of Japan

The proposed RTT is fairly tolerant of timing jitter,
as receiver can follow jitters on the signal by use of
path searcher, which follows delay variation of
paths.

switched speed and frequency range of the frequency
synthesizer of MSs?

Which service(s) of the standard set of ISDN bearer
services can the proposed RTT pass to users without
fixed network modification.
The proposed RTT provides equivalent services to
the fixed ISDN up to 2Mbit/s without any fixed
network modification. In this case, “equivalent
services” indicate connection and protocol
compatibility. The services provided by the
proposed RTT may not be fully compatible with the
fixed ISDN in terms of network communication
quality, such as delay and BER/FER, determined
by the recommendations ITU-T G series.
A1.4.8
Characterize any radio resource control capabilities that
exist for the provision of roaming between a private
(e.g., closed user group) and a public IMT-2000
operating environment.
Roaming between a private system and a public
system should be considered and realized through a
procedure in the higher layer. Therefore, it has not
been discussed in the proposed RTT.
A1.4.9
Describe the estimated fixed signalling overhead (e.g.,
broadcast control channel, power control messaging).
Express this information as a percentage of the
spectrum which is used for fixed signalling. Provide
detailed explanation on your calculations.
In downlink, system and cell specific information
are broadcast by the broadcast control channel.
Reference (pilot) symbols for coherent detection,
power control commands, and rate information are
provided in dedicated physical control channel
(DPCCH).
FDD mode :
In uplink, DPCCH uses fixed 16kbps Q-branch
channel, while DPDCH uses variable rate I-branch
channel. In downlink, DPCCH is time multiplexed
with DPDCH, and its rate can be variable
depending on the DPDCH rate. The signalling
overhead of DPCCH in dedicated physical channel
is ranging from 2.8% up to 28% in downlink, while
5.9%-33% in uplink.
TDD mode :
In both links, DPCCH is time multiplexed with
DPDCH, and its rate can be variable depending on
the DPDCH rate. The signalling overhead of
DPCCH in dedicated physical channel is ranging
from 0.9% up to 32%.

What are the signal processing estimates for both the
handportable and the BS?
–øMOPS (millions of operations per second) value of
parts processed by DSP (digital signal processing),
– gate counts excluding DSP,
–øROM size requirements for DSP and gate counts
(kbytes),

equalization, channel coding, error correction, diversity
processing (including Rake receivers), adaptive antenna
array processing, modulation, A-D and D-A converters
and multiplexing as well as some IF and baseband
filtering. For new technologies, there may be additional
or alternative requirements (such as FFTs etc.).

Dropped calls : describe how the RTT handles dropped
calls. Does the proposed RTT utilize a transparent
reconnect procedure – that is, the same as that
employed for handoff?
At the link lost caused by shadowing or
interference, MS and BS try to reconnect using
reconnection type control,
A1.4.15
Characterize the frequency planning requirements:
– frequency reuse pattern: given the required C/I and
the proposed technologies, specify the frequency
cell reuse pattern (e.g. 3-cell, 7-cell, etc.) and, for
terrestrial systems, the sectorization schemes
assumed;
–øcharacterize the frequency management between
different cell layers;
– does the RTT use an interleaved frequency plan?
–øare there any frequency channels with particular
planning requirements?
– all other relevant requirements.
NOTE 1 – The use of the second adjacent channel
instead of the adjacent channel at a neighbouring cluster
cell is called “interleaved frequency planning”. If a
proponent is going to employ an interleaved frequency
plan, the proponent should state so in § A1.2.4 and
complete § A1.2.15 with the protection ratio for both
the adjacent and second adjacent channel.
1-cell reuse
3/6 sectorization is used
Describe the capability of the proposed RTT to
facilitate the evolution of existing radio transmission
technologies used in mobile telecommunication systems
migrate toward this RTT. Provide detail any impact and
constraint on evolution.
The proposed RTT is based on a complete new
radio interface suitable for 3G systems considering
the feasibility of dual mode terminals with typical
nd
2 generation systems, e.g. PDC, GSM and IS-95.
A1.4.16
No frequency planning requirements
No
No
Therefore it does not have any technical constraints
and impacts imposed on the proposed RTT to
nd
achieve the evolution from 2 generation systems.
The migration in terms of service aspects can be
achieved by using dual mode terminals in a
transition period, because the proposed RTT will
provide IMT-2000 services in addition to those
nd
provided by 2 generation systems.
RTT proposal of Japan
ANNEX1
A1.4.17
Technologies Description Template
Are there any special requirements for base site
implementation? Are there any features which simplify
implementation of base sites? (terrestrial only)
No.
The proposed RTT is based on CDMA architecture
and has an asynchronous operation mode between
BSs. It allows operators to deploy their networks
into all environments supported by the RTT
without any frequency planning or any
synchronization between BSs.
The BSs of the proposed W-CDMA system consist
of fewer transceiver units than that of conventional
FDMA/TDMA systems, because the BSs of the
W-CDMA system can adopt common transceiver
architecture. In contrast, the BSs of conventional
systems require dedicated transceiver units for each
channel.
Moreover, the inherent property of W-CDMA that
frequency reuse factor is one and the system
capacity is determined by interference power in
each sector allows to increase the capacity by
sectorizing more precisely without any difficulties.
These features provide flexible enhancement of the
system performance according to the increase of
users and demands for quality requirements.

Link Budget Calculation
Followings are some assumptions that were used in the link budget calculations. Basically, all
link budgets are calculated based on unloaded systems. This means that the received
interference density (RX interference density) is zero (set to -1000dBm/Hz in the tables), and
Maximum total transmitter (TX) power is set as the same value as Maximum TX power per
traffic channel.
Maximum TX power per traffic channel.
Maximum TX power per traffic channel is the same value as the Average TX power per traffic
channel that is specified in M.1225. However, TX power control is included in the link-level
simulations to provide Eb/No to find coverage, so the maximum transmitted power could be
higher than the average TX power due to TX power control.
The increase of TX power is
denoted in the row as “Power control TX power increase”.
In TDD mode, maximum TX power per traffic channel is not the same as the Average TX
power per traffic channel because of duty ratio (1/2[TX/RX] * 19/20[guard time]).
Handover gain , Log-normal fade margin
The handover gain and log-normal fade margin are calculated for 95% area coverage with a
shadowing correlation of 50%.
See the Attachment for Link Budget Calculations for details.
Required Eb / ( No + Io )
The values for required Eb / ( No + Io ) are provisional.
The proper values shall be derived
from the outcome of further link-level simulations. Also, (Total effective Noise + interference
Density) and receiver sensitivity (RX sensitivity) are determined by required Eb / ( No + Io ).

Attachment for Link Budget Calculations:
Log-Normal Fade Margin and Handover Gains in M.1225 Link Budget Template
1. Introduction
This document presents a method to derive the Log-Normal Fade Margin and Handover Gains
described in the link budget template in M.1225 “Guideline for Evaluation of Radio
Transmission Technologies for IMT-2000” [1].
2. Log-Normal Fade Margin
The M.1225 link budget item Log-Normal Fade Margin is defined as the margin required to
provide the specified coverage at the border of a single isolated cell, i.e a cell with no ability to
perform a handover. The margin for a given coverage at cell border can be easily derived by:
Let denote the zero mean log-normal fading with standard deviation %, and let fading
denote the fade margin. Then the outage probability, i.e (1 - the coverage at cell border) or the
probability that the performance is worse than for unshadowed propagation, becomes
∞

However, M.1225 specifies the coverage figure as an area coverage of 95% which has to be
transformed to a coverage at cell border to be applied to (1). The relationship between area
coverage and coverage at cell border for a single cell has been established in [2]. The relation
changes with % and the path loss exponent. Calculated values of the log-normal fade margin
for the different environments specified in M.1225 and for different coverages are given in
Table 1. The values corresponding to the given area coverage probability of 95% are
specifically marked by shaded cells in the table. Furthermore, values for coverage at cell border
equal to 90% and 95% are given, since the definition of coverage in M.1225 is vague, which
might result in different interpretations made by different proponents as to which coverage
figure to use.
3. Handover Gain
The Handover Gain is specified as the gain (or loss) due to handover at the boundary of two
cells, where equal average loss to each of the two cells and a shadowing correlation of 50% is
assumed. The derivation of a more accurate and realistic handover gain considering all BSs of
the system could be accomplished by a simple system simulation. However, the above definition
of M.1225 has to be followed, only considering a point on the boundary between two cells
where there is no possibility to perform handover to any other cells.

Calculations with the above assumptions have been made by Viterbi et al in [3] resulting in
margins including both the fade margin and the handover gain. For hard handover a very
pessimistic assumption is made that the MS always is connected to the closest BS irrespective to
the fading conditions to other BSs in the system. The assumptions lead to exactly the same
expression for the total log-normal fade margin plus handover gain as was used for the fade
margin for a single cell in (1), i.e Viterbi assumes a handover gain equal to zero for hard
handover. However, the modeling in [3] of the soft handover as an ideal handover seems
reasonable. An ideal handover means that the MS is always connected to the BS to which it
experiences smallestr attenuation. Soft handover in the IS-95 uplink is implemented as a
selection diversity on a per speech frame basis, which is a faster process than the log-normal
fading. In the downlink, macro diversity combining is done in the RAKE receiver, allocating the
available fingers for the best multi-path rays from the BSs participating in soft handover. The
outage probability, as derived in [3], for a MS located at equal distances to the BSs of a two-cell
system is

for a 50% correlation of the log-normal fading to the two BSs, where ideal is the fade margin

plus the handover gain. Numerical evaluations of (2) for the specified environments and
coverage figures result in the handover gain figures for ideal handover in Table 1 after
subtracting ideal from the corresponding log-normal fade margins, i.e Handover Gain = fading
–ideal. Again the figures corresponding to 95% area coverage probability are marked by shaded
cells in the table.
Hard handover is often modeled with a handover threshold. As soon as the signal strength from
any BS exceeds that of the current BS by the handover threshold or more, the MS will perform a
handover to that BS. When determining which BS the MS is connected to, any BS to which the
attenuation is within the handover threshold from the smallest attenuation among the different
BSs is a candidate, and all candidates are equally probable. For a MS located at equal distances
from the BSs of a two-cell system, this means that the outage probability is the sum of
1) The probability that the log-normal fading to the two BSs exceeds the required margin
simultaneously.
2) The probability that only the log-normal fading to the BS connected to exceeds the required
margin while the difference between the fading values for the two BSs are smaller than the
handover threshold.
The first of the above components can be expressed as (2) with ideal replaced with another
margin, say hard . To derive an expression for the second component, let
ξ + ξi
ζi =

i ∈ {1,2}

as desired. The same approach was used when deriving (2). Now the second of the two
probability components can be rewritten as,

Pout ,2 = Pr{ζ1 > γ hard , ζ 2 < γ hard , ζ1 − ζ2 < ∆ HO } + Pr{ζ1 > γ hard , ζ 2 < γ hard , ζ 2 − ζ1 < ∆ HO } =

The first part of (6) (corresponding to (2)) is easily evaluated numerically, while the second part

of ≤ 0.5 mean opinion score unit (5 point
scale) relative to the error-free condition (G.726 at 32 kb/s)
*
Radio dependent delay within PLMN
excluding CODEC delay is assumed as 35ms.
Thus, the proposed RTT can satisfy the required
delay for data transmission.
Speech PLMN delay depends on CODEC delay,
and CODEC delay is assumed as 45ms.
Thus, the objective value for the total speech delay in
PLMN is 80ms or less.
G.174, ß 7.5
Explanation is requested when the candidate SRTT checks the No box.
The source Recommendation suggests numerical limits for the overall delay, but provides no guidance about the measurement techniques. Moreover there is an apparent
inconsistency with ITU-T Recommendation G.114, where the value of 40 ms is indicated as the ‘objective’ value. These issues are addressed in a liaison statement
sent to the relevant ITU groups. Until TG 8/1 receives a response and resolves this issue, proponents should submit
candidates providing delay values using the methodology specified in Recommendation ITU-R M.1225.

SUMMARY RTT proposal of Japan
1. PERFORMANCE EVALUATION
The performance of the proposed SRTT has been evaluated by means of computer simulations. This
evaluation is carried out based on the methods and conditions described in ARIB’s Evaluation Methodology
[1] Annex 2. Table 1 shows the simulated cases that are chosen by following the descriptions of Table 1 in
ARIB’s Evaluation Methodology Annex 2. In Table 1 below the priorities for different simulation cases
made by ARIB are shown.
The performance evaluation consists of two stages: the link level simulation and the system level simulation.
Each stage includes both up-link (UL) simulations and down-link (DL) simulations. This document describes
the detailed conditions and assumptions for each stage.
In this document, abbreviations LDD, LCD and UDD are used to identify three types of data services. The
correspondences between these abbreviations and the expressions used in ITU-R M.1225 Annex2 (e.g. in
Table 1) are listed below.
LDD (Low Delay Data bearer services): data (circuit switched, low delay)
LCD (Long Constrained Delay data bearer services): data (circuit switched, long delay constrained)
UDD (Unconstrained Delay Data bearer service): data (packet)
Regarding data services, the coding method should be carefully chosen since it has a significant impact on the
performance. From this point of view, in the RTT proposal, the application of turbo-codes is proposed. It has
been shown that the turbo-codes provide data transmission with higher efficiency, i.e. data transmission with
lower Eb/I0, than using the conventional concatenated coding based on both convolutional coding and ReedSolomon coding. This report presents the evaluation results when concatenated coding is used for data
transmission. Some results are presented to show the expected improvement by employing turbo-codes. The
complete results that cover all simulation cases and clsrrify the characteristics of turbo-codes will be
presented at a later stage.

* The quality of service is defined by the bit error rate according to the descriptions in ARIB’s Evaluation
Methodology. However, in the simulations, a frame error rate of 10% is used as a criterion. The BER
performance is guaranteed by the automatic repeat request mechanism. Detailed explanations will be found in
the descriptions on the system simulations in this document.
RTT proposal of Japan
** Results of LCD 384 and UDD 384 are partially presented in this document. The bit rate of 144 kbps has a
high priority because it corresponds to the minimum performance capability defined in the circular letter from
ITU-R TG8/1. The complete results of LCD 384 and UDD 384 will be presented in later versions of this
document.
1.1 Simulation assumptions common for both FDD and TDD
1.1.1 Channel Models
The channel models given in M.1225 Annex 2 cannot be used immediately, since the time resolution of the
simulation model is merely one sample. For the simulations the following model was used:
Each ray is split into two rays, one to the sample to the left and one to the sample to the right. The power of
these new rays is such that the sum is equal to the original power, and the power of each of the new rays is
inversely proportional to the distance to the original ray. Finally, the power of all rays on one sample are
added up and normalized. This yields a model with a number of independent Rayleigh fading rays on the
sampling instants.

Figure 1. Modified channel models used in the simulations.
The rays picked up by the RAKE receiver are marked with large squares in the figure, while other rays are
marked with small diamonds. No special link simulations were made for soft handover situations. In a soft
handover the result from two single connection-RAKEs are combined. For the Vehicular case this would
mean 8 RAKE fingers. However, the number of RAKE fingers can be lowered in soft handover without
affecting the performance, so 4 - 6 fingers should suffice.
Simulations have been made for mobile station speeds of 3 km/h and 120 km/h, corresponding to Doppler
frequencies of 5.6 Hz and 213 Hz respectively for the uplink.
1.1.2
System-Level Simulations
1.1.2.1 Simulation Environment
The simulation environments are described in ARIB’s Evaluation Methodology Annex 2. Implementation
assumptions are described below.
The Outdoor to indoor and pedestrian deployment environment is a Manhattan-like environment with the
block size of 200 m and low speed (3 km/h) users. This environment consists of 72 base stations, which are
located as described in ARIB’s Evaluation Methodology Appendix 2. The base stations use omni-directional
antennas and are deployed 10 m above ground, which is a hight lower than roofs. The radio propagation
going above the roof s is also included in the system simulation model. The street width is 30 m and it is
assumed that the pedestrians are moving in the middle of the street.
The Indoor office environment characterises a three-floor office building where users are moving (3 km/h)
between an office room to the corridor or vice versa. The base stations (60 base stations all using omnidirectional antennas) are deployed in every second office room.
The Vehicular environment is a classic macro environment, with a site-to-site distance of 3km. Tri-sectorised
sites are used, i.e. each site is serving three sectors (cells). The speed of the mobile stations is 120 km/h.
Wrap around is used in order to make an infinite cell plan, i.e. there are no border effects in the simulations.
1.1.2.2 Downlink Assumptions
1.1.2.2.1 Downlink Orthogonality
In the System-Level simulation, the received downlink SINR by a single BS is calculated assuming two finger RAKE reception. Although inter-cell signals are orthogonal in downlink, multi-path propagation
RTT proposal of Japan
25 0 0 0
disturbs the orthogonality in accordance with the power of each path (path intensity). Inter-cell interference
power due to multi-path is calculated from predetermined path intensity ratio. The path intensity ratios are
specified for each environment by referring to the channel models defined in Fig.1.A maximum of two
pathswas considered for each channel model and other paths were ignored. Table 2 describes the path
intensity ratios for the propagation model in each environment.
Table 2. Path intensity ratios for different propagation models in each environment.
Propagation model
Path intensity ratio*
Indoor office A
0.90 : 0.10
Outdoor to indoor and
pedestrian A
0.94 : 0.06
Vehicular A
0.60 : 0.40
*For instance, ratio of 1.0 : 0.0 means completely orthogonal.
1.1.2.2.2 Downlink Code Limitation
Note that it is assumed that a sufficient number of orthogonal codes are available in all downlink SystemLevel simulation results that appear hereinafter. However, in practical system, the number of orthogonal
codes is limited, and thus some of the capacities may be limited due to lack of codes. The number of
orthogonal codes depends on a couple of design parameters and optimum set of these parameters has not been
elaborated yet at the submission of this evaluation document, This is an issue for further design elaboration.
1.1.2.3 Soft / Softer Data Combining
For the Indoor office and the Outdoor to indoor and pedestrian environment soft handover is used between
base stations. This means that the uplink C/I (or SIR = PG×C/I) is calculated as selection diversity and the
downlink as maximum ratio combining (a sum of the received C/I from each base station). For the Vehicular
environment softer handover is used, i.e. the mobile is connected to several sectors belonging to the same site,
which will affect the calculation of the uplink C/I. Therefore the uplink C/I for all sectors belonging to one
site is calculated as maximum ratio combining. Soft handover in the Vehicular environment is treated as
regular selection diversity.
The softer handover data combining (maximum ratio combining) is performed on layer 1 in the W-CDMA
concept. Softer handover is used only in the Vehicular environment. In the uplink and downlink the SIR during
softer handover is modelled as:
SIRcombined =
∑ SIRsector
sec tors
The combined downlink (maximum ratio combining) SIR during soft handover is modelled as:
SIR DL,combined =
∑ SIR sec tors
sec tors
The combined uplink (selection diversity) SIR during soft handover is modelled as:
SIRUL ,combined = max( SIRsec tor )
sec tors
1.1.2.4 TX power control
Fast SIR-based power control is assumed in both uplink and downlink, and the power of the transmitters is
balanced to meet the averaged SIR. The output power is adjusted in accordance with received SINR value
including fast fading for some UDDs except for the Vehicular cases and the 3km/h cases (Indoor office and
RTT proposal of Japan
Outdoor to indoor and pedestrian). TX power increase due to power control can be modelled by this
assumption. For the Vehicular cases, fast fading is not included in the received SINR because, in such a high
speed MS environment, averaging of the received signal is expected and the power control cannot trace
fading.
1.1.2.5 Radio Resource Management
Soft/softer handover is used for circuit-switched services. The soft/softer handover algorithm simply
connects the strongest, based on pathloss (excluding fast fading), base stations within the handover window.
The maximum active set size is two and the soft/softer handover window threshold is set to 3 dB. The
algorithm is executed every 0.5 second for the 3 km/h cases (Indoor cases and Outdoor to Indoor Pedestrian
cases) and 0.01 second for 120 km/h cases (Vehicular cases). Shorter active set modification period of
Vehicular environment is to track the changes in path loss due to fast movement of MS. This period can be
raised by more than 0.01 sec by a simple alternative method: increase the handover window threshold and./or
the maximum active set size. Measurement errors are not included. No soft handover is currently used in the
packet simulations; the user simply connects to the strongest base station.
For the UDD service, dedicated channel packet transmission is used. No random access / forward access
signaling is included in the results.
It is assumed that a control information block can be re-transmitted in the next packet block, i.e. that the
ACK/NACK channel is error free and infinitely fast. A packet data user is queued if no resources are
available. If there is a choice between queuing two users, the latest arrived user is queued.
1.1.2.6 Performance Measures
Circuit-Switched Services
Two circuit-switched services, speech and LCD, have been evaluated by means of dynamic system
simulations. The performance measure of the speech (8 kbps, 50% voice activity) and LCD services is that
98% of the users are satisfied. A user is satisfied if all three of the following constraints are fulfilled:
1. The user does not get blocked when arriving to the system.
2. The user has sufficiently good quality more than 95% of the session time. The quality threshold is defined
-3
as BER =10
-6
(speech) or BER = 10 (LCD).
3. The user does not get dropped. Speech and user is dropped if BER > 10-3 for 5 s and LCD 2048, LCD 384 ,
-6
LCD 144 and LCD64 users are dropped if BER > 10 for 5 s. 26 s, 69 s and 156 s respectively.
Packet Services
Four different packet data services have been evaluated: UDD64, UDD 144, UDD 384 and UDD 2048.
The performance measure of the packet services is that 98% of the users are satisfied. A user is satisfied if all
three of the following constraints are fulfilled:
1. The user does not get blocked.
2. The user does not get dropped.
3. The active session throughput shall not be below 6.4kbps(UDD 64), 14.4 kbps (UDD 144), 38.4 kbps
(UDD 384) or 204.8 kbps (UDD 2048).
The time waiting on ACK/NACK (i.e. when the transmitter buffer is empty) is not included when calculating
the active session throughput. A data packet is divided into packet blocks, each of which has a block size of
304 bits. The block size is uniform, independent of the bearer rate, and thus different time length of a packet
block is applied to each of UDD64, UDD144, UDD384 and UDD 2048. ACK/NACK reception is carried
out every packet block. If the data packet that shall be transmitted has less bits than can be transmitted in a
RTT proposal of Japan
frame, dummy bits (or rather dummy blocks) are added. These dummy bits are not included when calculating
the session throughput, however they will increase the interference in the system.
Furthermore, the quality of service (QoS) for packet services is defined using BER in Table 1 of ARIB’s
Evaluation Methodology Annex 2. However, in the link and system level simulations, it is convenient to
define QoS using block error rate (BLER). The BER performance is guaranteed by the automatic repeat
-6
request (ARQ) mechanism. BER of 10 will be achieved when ARQ re-transmits the failed block six times at
-6
maximum because the probability that all of the six trials fail is 10 . In the systems level simulation, specific
ARQ algorithms are not considered, but a very simple method and average decrease of throughput are
considered.
1.2 Detailed Conditions and Assumptions for W-CDMA/FDD
1.2.1 Simulation Model
1.2.1.1 Link-Level Simulations
The simulation model used here is based on the ARIB’s Evaluation Methodology Annex 2. However, more
detailed methods are required in actual simulations and there are parameters to be determined. Table 3 and 4
summarise the detailed simulation parameters and methods used in the simulations for UL and DL,
respectively. In Tables 5 to 10, the detailed simulation parameters for specific services are presented. In the
simulations, sampling was made at chip level. Fast power control is included in all simulations. In actual
systems, power control commands are sent on the backward channel, i.e. the uplink power control commands
are sent on the downlink and vice versa. However, in the simulation, random errors with a certain error
probability are added to the power control commands. To find the appropriate values for this error
probability of TPC symbols, the errors of TPC symbols are collected under the simulation condition that
-3
provides the predetermined BER for information bit stream, e.g. BER of 10 for speech. Please note that the
error probabilities of 4% and 1% are used for speech and high-speed data respectively in both UL and DL.
Link-level simulations assume an unlimited dynamic range for fast power control, and the delay in the power
control loop is one slot. The power amplifier is not modeled, i.e. an ideal amplifier is assumed.
A fixed searcher is used in the receiver, i.e. the receiver knows the delay of all rays and picks up the energy of
some rays using a fixed set of fingers in the RAKE. In the section on channel models the rays picked up by the
RAKE are shown.
All interference is modeled as additive white Gaussian noise.

1.2.2 Results
1.2.2.1 Link-Level Simulations
The Eb/No values presented here are the actual Eb/No values needed in the receiver to achieve the
corresponding BER, FER and BLER. The Eb/No values include all overhead, i.e. the DPCCH (Dedicated
RTT proposal of Japan
Physical Control Channel: reference bits, power control bits, FCH) and overhead on the DPDCHs
(Dedicated Physical Data Channels) such as CRCs, block numbers and tail bits for the convolutional code. In
other words, the Eb value contains all energy needed to transmit one information bit. Energy from common
broadcast channels is not included in the link-level results.
After coding of the DPDCH rate matching is applied, using puncturing or repetition. On the DPCCH rate
matching is always performed using repetition. The rate matching used for the different services are given
below, e.g. 9/10 rate matching means “9 bits in, 10 bits out” or repetition of every 9:th bit.
1.2.2.2 System-Level Simulations
Dynamic system simulations have been performed for three different services in three different environments
described in ARIB’s Evaluation Methodology Annex 2. In these simulations all base stations are assumed to
be equipped with one 4.096 Mcps W-CDMA carrier using 5 MHz carrier spacing (assuming 3 carriers
within 15 MHz). It is likely that the concept will perform better if a larger bandwidth is used for higher data
rates due to a better trunking efficiency. Therefore all results of higher data rate services shall be regarded as
pessimistic results. Also, the simulations of the UDD services have only used a fixed bit-rate radio bearer,
which will also decrease the performance of the UDD services.
1.2.2.2.1 Circuit-Switched Services
Two circuit-switched services, speech and LCD, have been evaluated by means of dynamic system
simulations. The performance measure of the speech (8 kbps, 50% voice activity) and LCD services is that
98% of the users are satisfied. No admission control has been used, therefore no users are blocked. Also, the
simulation results show that cell capacity in all cases is limited by the requirement that a satisfied user must
have sufficiently good quality more than 98% of the session time and not by the dropping criteria. This means
that neither blocking nor dropping is assumed in these simulation results, hence the offered load (Erlang
capacity) is same as the served load.
The W-CDMA concept uses fast power control also in downlink. This means that slow moving users can
compensate for the fast channel fading. High-speed users do not require good tracking of the fast channel
fading due to the gain from coding and interleaving.
In Table 15 speech results are found. LCD results are presented in Table 16.
Please take note that, in Tables 15 and 16, the term “cell” is defined as an area covered by a sector. The
speech service is evaluated using 50% voice activity. However, the DPCCH is transmitted with a constant
bit-rate independent of the speech user information rate (8 kbps or 0 kbps information bit-rate). Therefore, the
spectrum efficiency will increase more than 30% if a voice activity of 100% is used, due to the decreased
DPCCH (relative) overhead.

1.3 Detailed Conditions and Assumptions for W-CDMA/TDD
1.3.1 Simulation Model
1.3.1.1 Link-Level Simulations
The simulation model used here is based on the ARIB’s Evaluation Methodology Annex 2 as similar to the
FDD mode. However, more detailed methods are required in actual simulations and there are parameters to
be determined. Table 20 and 21 summarise the detailed simulation parameters and methods used in the
simulations for UL and DL, respectively. In Tables 22 to 25 the detailed simulation parameters for specific
services are presented.
In TDD mode, each 10ms frame consists of 16 time slots, each allocated to either uplink and downlink. A
flexible time slot allocation, where time slots can be arbitrarily allocated to uplink and downlink except for
the first time slot of downlink, is adopted as shown in Fig.2 [2]. Obviously, the same timeslot allocation is
needed for all base stations within the whole area of synchronization. This flexible allocation improves the
ability of the TDD mode to efficiently work in different environments and deployment scenarios.
10 ms
Fig.2 Uplink/Downlink Allocation
In the simulations, symmetric uplink/downlink allocation with multiple-switching-point configuration is used
as shown in Fig. 3. Only in the case of LCD 2048kbps, asymmetric allocation with multiple-switching-point
shown in Fig.4 is used. The configuration of Fig.4 shows the case of LCD 2048kbps for DL, on which 14 time
slots are assigned for DL and the other time slots for UL. For LCD 2048kbps for UL, the opposite
allocation,i.e 14 time slots are assigned for UL and the other time slots for DL is used. The multipleswitching-point configuration is obviously the best from the viewpoint of a fast power control and transmit
space diversity. Furthermore, frame format and channel coding in the simulations are decided on the
assumption that all time slots on the same direction are assigned for each channel shown in Figs. 3 and 4. The
allocation using all time slots is obviously the best from the point-of-view of interleaving gain, lower peakpower and coverage efficiency. The perch channel used for open-loop power control of UL is assigned and
code-multiplexed to 8 time slots of DL in Fig.3 in all case of UL evaluation.
10 ms
Fig. 3 Symmetric UL/DL allocation with multiple-switching-point
10 ms
Fig. 4 Asymmetric UL/DL allocation multiple-switching-point (LCD 2048kbps on DL)
In the simulations, sampling was made at chip level. Fast power control is included in all simulations.
RTT proposal of Japan
Fast open-loop power control on uplink based on the estimation value of propagation loss from downlink
perch channel is used. In actual system, SIR-based closed-loop power control is combined with open-loop
power control in order to compensate for the communication quality difference among channels. However,
this link-level simulation does not need the compensation for it as same as outer loop control. Therefore,
open-loop power control without combining closed-loop control is applied to uplink link-level evaluation.
The perch channel is assumed to be transmitted at a fixed power and from each antenna with different
spreading code and the same scrambling code respectively. The received signal power is calculated by
combining each perch channel. The average Eb/No value of perch channel is assumed to be 10dB.
Fast closed-loop power control based on SIR is used on downlink. Power control commands are sent on the
backward channel, i.e. the downlink power control commands are sent on the uplink and vice versa. However,
in the simulations, random errors with a certain error probability are added to power control commands. To
find the appropriate values for this error probability of TPC symbols, the errors of TPC symbols are
collected under the simulation condition that provides the predetermined BER for information bit stream, e.g.
-3
BER of 10 for speech. Please note that the error probabilities of 4% and 1% are respectively used for
speech and high-speed data. Furthermore, selective transmit diversity is applied for downlink. The received
signal power of the previous uplink slots is measured for each of the antennas at base station. The antenna
with the highest received power is selected to transmit the downlink information. The average Eb/No value of
uplink channel is assumed to be 5dB.
Link-level simulations assume unlimited dynamic range for the fast power control, and the delay in the
downlink power control loop is two slots (1.25ms). The power amplifier is not modeled, i.e., an ideal
amplifier is assumed.
A fixed searcher is used in the receiver, i.e., the receiver knows the delay of all rays and picks up the energy
of some rays using a fixed set of fingers in the RAKE. In the section on channel models the rays picked up by
the RAKE are shown.
All interference is modeled as additive white Gaussian noise.

1.3.1.2 System-Level Simulations
Environment models, power settings and other parameters of System-Level simulations of TDD mode are the
same as those of FDD mode in Tables 11 to 14.
RTT proposal of Japan
1.3.2 Results
1.3.2.1 Link-Level Simulations
The Eb/No values presented here are the actual Eb/No values needed in the receiver to achieve the
corresponding BER, FER and BLER. The Eb/No values include all overhead, i.e., the DPCCH (Dedicated
Physical Control Channel: reference bits, power control bits, FCH) and overhead on the DPDCHs
(Dedicated Physical Data Channels) such as CRCs, block numbers and tail bits for the convolutional code. In
other words, the Eb value contains all energy needed to transmit one information bit. Energy from common
broadcast channels is not included in the link-level results.
After coding of the DPDCH, rate matching is applied using puncturing or repetition. On the DPCCH, rate
matching is always performed using repetition. The rate matching used for the different services are given
below, e.g., 9/10 rate matching means “9 bits in, 10 bits out” or repetition of every 9:th bit.
1.3.2.2 System-Level Simulations
At this moment of the submission of this document, the system-level simulation results for TDD mode are
estimated by interpolation of the results for FDD mode because it was confirmed that cell capacity and
spectrum efficiency are well proportional to the required Eb/No gain in each environment.
Dynamic system simulations have been performed for three different services in three different environments
described in ARIB’s Evaluation Methodology Annex 2. In these simulations all base stations are assumed to
be equipped with one 4.096 Mcps W-CDMA carrier using 5 MHz carrier spacing (assuming 3 carriers
within 15 MHz). It is likely that the concept will perform better if a larger bandwidth is used for higher data
rates due to a better trunking efficiency. Therefore all results of higher data rate services shall be regarded as
pessimistic results. Also, the simulations of the UDD services have only used a fixed bit-rate radio bearer,
which will also decrease the performance of the UDD services.
1.3.2.2.1 Circuit-Switched Services
Two circuit-switched services, speech and LCD, have been evaluated by means of dynamic system
simulations. The performance measure of the speech (8 kbps, 50% voice activity) and LCD services is that
98% of the users are satisfied. No admission control has been used, therefore no users are blocked. Also, the
simulation results show that cell capacity in all cases is limited by the requirement that a satisfied user must
have sufficiently good quality more than 98% of the session time and not by the dropping criteria. This means
that no blocking or dropping is assumed in these simulation results, hence the offered load (Erlang capacity)
is same as the served load.
The W-CDMA concept uses fast power control also in downlink. This means that slow moving users can
compensate for the fast channel fading. High-speed users do not require good tracking of the fast channel
fading due to the gain from coding and interleaving.
In Table 26 speech results are found. LCD results are presented in Table 27.
Please take note that, in Tables 26 and 27, term “cell” is defined as an area covered by a sector. The speech
service is evaluated using 50% voice activity. However, the DPCCH is transmitted with a constant bit-rate
independent of the speech user information rate (8 kbps or 0 kbps information bit-rate). Therefore, the
spectrum efficiency will increase more than 30% if a voice activity of 100% is used, due to the decreased
DPCCH (relative) overhead.

2. EFFECT OF APPLYING TURBO-CODES TO DATA SERVICES
This section evaluates the effect of applying turbo-codes[3] to data services. As mentioned earlier, only a
few cases are investigated. Please note that these parameters do not agree with the format in system
description, and that the channel environment is not the same as the channel models of the evaluation results in
chapter 1.1. However, the investigation concentrates on analyzing the effect of turbo-codes itself, and
therefore, it is considered that the differences in these assumptions will not significantly affect the results.
-6
Table 31 shows the comparison of the required Eb/Io values for BER=10 at 64kbps data channel of
cc(convolutional coding)+RS coding and turbo-codes. Table 32 shows simulation parameters (frame format
and channel environment) while Table 33 shows interleaving patterns of a MIL(Multi-stage interleaving
method[4]. Figures 1, 2 and 3 explain the meanings of the expressions used in Table 33.
Referring to Table 31, it is shown that the gain of applying turbo code instead of cc+RS is 0.4[dB] with 10ms
interleaving and 0.9[dB] with 80ms interleaving. However, it is known that in higher bit rate channels than
64kbps, turbo-codes become more effective [3]. The effect of applying turbo-codes, therefore, is expected to
be higher than the results shown in Table 31. The gain can also improve the results of system simulation, i.e.
spectrum efficiency.

RTT proposal of Japan
Service Requirements for Phase 1
The Phase 1 standardization of 3GMS is targeted based on a two-step approach.
Vol.1, 5.5
Step 1 is defined as a set of bearer channel capabilities which include the circuitmode bearer channels at up to 384 kbit/s and packet-mode bearer channel at 384
kbit/s for indoor and pedestrian environments.
Step 2 is defined as a set of bearer channel capabilities which include the circuitmode bearer channels at up to approximately 1.5Mbit/s and packet-mode bearer
channel at 2M bit/s for the indoor environments.
A 3GMS shall be capable of supporting pre 3G services and the details of
additional services shall be standardized at the time when Step 1
capabilities is determined.
Services to be considered for later phases
One of the service areas that can be augmented in the later phases will be those that Vol.1, 5.6
uses higher bit rate bearer capabilities becoming available in the wider range of
operating environments.
