TM500 TD-LTE SYSTEM OVERVIEW
The 3GPP’s Long Term Evolution (LTE) programmes are expected
to deliver an increasingly better mobile user experience through
improvements in end-user throughputs, sector capacity, and user
plane latency. To achieve this requires some significant changes in
parts of the network infrastructure and mobile user equipment.
The TM500 TD-LTE product is a major addition to the Aeroflex
TM500 family of 3GPP test mobiles and a substantial commitment by
Aeroflex to support the current and future technologies required for
3GPP LTE. Two key differentiators between FDD and TDD
technologies are the UL-DL asymmetry and the special sub-frame.
TM500 TD-LTE supports all UL-DL configurations defined by 3GPP
to account for symmetrical and asymmetrical network traffic. The full
range of special sub-frame configurations is also supported. Special
sub-frame is defined by 3GPP in order to avoid UL and DL interfering
to each other (each configuration applies to a different cell size).
Built upon a new and scalable software defined radio platform, the
TM500 TD-LTE product targets development, demonstration and
testing of 3GPP TD-LTE infrastructure equipment.
The range now also includes options for higher layers, higher
category UEs, LTE FDD and Multi-UE operation. With its layered
operation and automation interfaces the TM500 TD-LTE can
additionally operate within an automated or wrap around test
configuration.
Through years of experience in WCDMA/HSPA+ and working
closely with customers on LTE FDD development and
demonstrations, the TM500 TD-LTE product is primarily designed
to help support and accelerate the overall development and test
programme. The TM500 TD-LTE product offers the earliest access
to the latest 3GPP functionality, before real handsets, as well as
layered operation and high degree of logging and control.
Productivity enhancing tools simplify the development and running
of test scenarios and include advanced test features such forced
errors and event triggering. Highly flexible operation enables the
TM500 TD-LTE to be used in many customer configurations
including in the lab, over the air, manually or remotely or as part of
an automated test system.

TYPES OF TESTING (OPERATIONAL CONFIGURATIONS)
CONTROL AND LOGGING
The TM500 TD-LTE can be operated in a number of configurations.
Management of the TM500 TD-LTE is carried out through the Test
mobile Application (TMA) software supplied with the system. The
TM500 TD-LTE can also be controlled by an external system, such
as a customer’s remote automated test system.
TMA is an integrated software suite that provides an easy and
intuitive user interface for: creating and running test scripts; data
logging and measurements as well as the analysis of test sessions and
data. To enhance productivity The TMA incorporates valuable
features such as test step and template libraries, drag and drop
selection, session browser, command line, error monitor, real time
logging and graphical charting windows.
In the lab
The TM500 TD-LTE operates as a 3GPP specification compliant
UE test peer to support functional development, debug, integration
and test of TD-LTE eNode-B and core network equipment. The
TM500 TD-LTE can operate at component, module and system
level and with or without the use of a fading channel simulator.
Outdoors
Designed for use over the air, the TM500 supports the requirements of early drive testing and proof of concept trials, exercising
new features of the TD-LTE technology.
Demonstration
TM500 is ideal for demonstrating leading edge TD-LTE technology,
including maximum rate transmissions, MIMO operation etc. Using
its IP Driver interface, TM500 TD-LTE can support real time
applications via a TCP/IP connection including high definition video
streaming, files transfer, web browsing etc. The layered operation of
the TM500 TD-LTE enables it to support the demonstration of
partial as well as full complete network equipment configurations.
In the TM500TD-LTE the logging accounts for the UL-DL
asymmetry to facilitate debugging in cases where one UL/DL subframe carries HARQ ACK/NACK for multiple DL/UL sub-frames.
User can then not only test the HARQ functionality but also verify
that the eNodeB meets the processing time required in order to close
the round trip time.
Script Production: The TMA includes script control tools that
provide a fast and easy way to create and control test scripts via a PCbased graphical user interface. The tool includes a library of test
command sequences that enable easy configuration of test mobile
and the associated 3GPP parameters. The TMA also validates the
test scripts, detecting any sequencing or parameter range errors
before executing the test scenario on the TM500.
Measurements and Data Logging: The measurement tools enable
the user to selectively log and display measurement information from
the test. Detailed measurements from Layer 1, 2 and/or 3 tests can be
displayed in real time using the charting facility. In addition, all
measurements are logged to file for post test analysis. These log files
can be used to replay test sessions within the charting tool or can be
exported to other tools for further analysis.
Event Triggering: A new event-based triggering tool allows the user
to start the measurement logging based upon a specific event, such as
a 3GPP measurement or handover request. This powerful feature
allows the user to define, co-ordinate and analyze detailed test
scenarios.
TEST MODES
TEST CAPABILITIES/FEATURES
The TM500 incorporates a number of test modes which enable an
incremental, layered approach to development and testing of the TDLTE stack from the PHY layer and upwards. Detailed functionality
can be tested at a modular level, enabling very early testing of eNode
B features even during the development stage. TM500 supports test
features that enable early uplink and downlink operation to be
validated independently. In addition 3GPP control signalling can be
overridden and scripted to enable early test of closed control loops or
to simulate error or fault conditions.
To help accelerate testing and integration the TM500 TD-LTE
incorporates enhanced test and analysis features. These can also be
used to simulate test scenarios, enabling early module level testing
during development and integration phases.
HARQ Mode. This mode of operation provides detailed test features
targeting analysis of the PHY layer and HARQ retransmission
processes. Independent BER and BLER analysis are supported for
each HARQ process using data source/sinks configured to standard
PN or user defined data sequences. Used in conjunction with the
charting measurement tools, these features enable the user to
monitor the real time operation of the UL and DL physical data link.
MAC Mode. The MAC mode adds analysis of the full eNode B MAC
operation to the PHY / HARQ functionality. MAC mode adds MAC
header monitoring, MAC PDU creation and MAC SDU extraction to
the HARQ mode. The received payload data is evaluated for each
logical channel and HARQ using data sinks. BLER is measured using
the post-HARQ CRC results. Each logical channel can be connected
to a separate data source or sink.
Scripted Control & Corruption. TD-LTE relies on a number of
closed control loops which report information such as channel quality,
RF propagation conditions and data integrity. Typical closed loop
parameters include CQI, MIMO feedback (CSI), power control and
HARQ. Such information is normally based on real time
measurements over the air. To simplify the simulation and
repeatability of such scenarios, TM500 TD-LTE provides the ability
to override these signalled values using script commands and to
corrupt the control information.
EXAMPLE Configuration – Downlink HARQ Override.
In a laboratory environment with a static, cable connection between
the TM500 TD-LTE and the eNodeB it is likely that BLER will be
zero. If suitable fading channel simulator and interference generator
equipment is not available this can limit the testing of HARQ. The
TM500 TD-LTE provides the capability for early HARQ testing by
DL HARQ ACK/NACK override to force BLER. Using the TMA the
user scripts a sequence of ACK/NACKs for one or two codewords.
The user defined HARQ is then fed into the eNodeB over the UL.
RLC Mode. The RLC mode supports full RLC functionality
including Transparent Mode, Unacknowledged Mode and
Acknowledged Mode operation. This enables the user to analyse the
RLC, MAC and PHY operation within the eNode B, The data content
is transmitted and received as RLC PDUs, bypassing the PDCP layer.
RLC mode control is via specific configuration commands as well as
providing scripted control for SDU insertion into RLC buffers and
for logging of data and state information.
PDCP Mode. This mode adds PDCP header functionality, enabling
features such as PDU duplication and discard detection that may
occur during handover procedures.
Higher Layers. (option) The Higher Layers mode adds analysis of
RRC and NAS layer operation on the eNode B.
Data Generation and Evaluation:
The Ethernet interface can be used to source and sink real data
from any application running on a PC for example. Alternatively the
TM500 TD-LTE is able to transmit pre-defined data on the uplink
and analyse received data on the downlink. Data can also be routed
via an interface for external generation or analysis. The TM500
TD-LTE also includes a data service generator tool with which traffic data can be generated in profiles that simulate those encountered
with real world applications running over the network. These features are very powerful in providing repeatable and deterministic
data generation and analysis.

AUTOMATED AND REMOTE OPERATION
Remote and automated operation is essential for modern test
equipment. With the TM500 TD-LTE remote and automated
control interfaces the TM500 TD-LTE system can be controlled via
a standard Ethernet interface from the next room or another country.
The TM500 TD-LTE automation interface enables the supplied
management software or the customer’s own control system to
operate the TM500 TD-LTE commands, measurements, data
logging and displays. The automation interface also supports control
of multiple TM500s.
