  7. 7. Industry Achievements in TD-LTE Test Solutions Conformance Toolset Supports VoLTE and LTE-Advanced 2013 GTI Summit Anite’s Conformance Toolset for protocol and performance testing supports large number of GCF validated protocol conformance test cases for TD-LTE. This was confirmed at the CAG#36 meeting in October. The support for TD-LTE includes all of the immediate requirements such as TD-SCDMA and GSM inter-RAT, TD-LTE inter-band and LTE TDD/FDD inter-mode testing. Conformance Toolset also supports future requirements such as TD-LTE support for LTE-Advanced Carrier Aggregation and VoLTE. Anite’s China Mobile specific test case suite now supports over 1000 distinct tests, including Data Performance. These tests are run on SAS, Anite’s interoperability testing solution, which also supports future technology requirements such as VoLTE and LTE-Advanced. Simplified Envelope Tracking Test System Rohde&Schwarz, one of the leading test equipment manufacturers, provides a unique Test & Measurement solution to test Envelope Tracking Power Amplifiers/DC modulators. This achievement strengthens the LTE ecosystem by paving the way for future innovative Power Amplifier concepts that further drive the adoption of the global radio technology TD-LTE and LTE FDD. Power Amplifiers (PAs) are traditionally operated with a constant supply voltage. PAs are most efficient, if they work near its maximum output power. Considering a varying RF signal (like in particular for TD-LTE and LTE FDD) a significant portion of the energy will be dissipated as heat in the PA. Envelope Tracking is a technique to improve efficiency of PAs by modulating the DC supply according to the envelope of the I/Qsignal. As a result the PA is working in the efficient regions most of the time which translates in improved device battery times and increased end user experience. Power amplifier (PA) RF RF Envelope R&S®SMW200A 08 DC modulator Voltage/current probe, e.g. R&S®RT-ZD10 Device under test (DUT) R&S®FSW Rohde & Schwarz provides a unique Test & Measurement solution to test Envelope Tracking Power Amplifiers/DC modulators with Signal Generation of RF and envelope signal out of one box (R&S®SMW200A) and Signal Analysis of RF and envelope signal in one box (R&S®FSW). RF and related envelope signal are both generated in the R&S®SMW200A which enables a precise delay adjustment between both signals in pico second resolution without any synchronization procedure. Different shaping methods can be applied in real time to the envelope signal. A test time reduction can be achieved by the automatic envelope voltage adaptation for different RF power levels, which eliminates the need for time-consuming manual recalculation of the envelope signal. The Signal Analyzer R&S®FSW provides fast measurement speed for EVM and ACLR and high dynamic range. 07
  8. 8. Industry International TDD/FDD VoLTE Calls Demonstrated between China and South Korea VoLTE has been identified as China Mobile’s TD-LTE voice solution. Earlier in June this year, Li Yue, president and CEO of China Mobile announced VoLTE white paper aiming at accelerating the development of TDD VoLTE and comprehensively bridging the gap between TDD and FDD VoLTE. To promote the global mobile communications industry and accelerate the development of TDD VoLTE, China Mobile launched VoLTE trial in Hangzhou, Chengdu, Guangzhou and Nanjing in August 2013.
