Achievements

CoMP Trials Have Been Implemented in TD-LTE Network

UL CoMP Trial in TD-LTE Network

DL CoMP Trial in TD-LTE Network

CMCC and Ericsson have made extensive trials to evaluate uplink (UL) CoMP performance for TD-LTE.

• Successful demonstrations have been made in a larger scale field trials network using multi-cell and multi-user scheduling for UL CoMP

• The results indicate that significant gains in cell edge performance, in the range of 50%-100%, in a loaded Marco cell network

• This shows that UL CoMP can also be an efficient way of interference mitigation in addition to performance enhancement through multi-point reception

• UL CoMP has also been demonstrated and evaluated for heterogeneous network configurations

• In such environments similar and in certain interference configurations even higher benefits can be observed compared to the Marco cell environment

• UL CoMP can be widely applied in various environments to improve cell-edge performance. It also demonstrates Ericsson’s product capability

CMCC and ZTE have successfully implemented downlink (DL) CoMP trial in TD-LTE network in Guangzhou, China:

• Industry’s first DL CoMP-JT/CS trial in TD-LTE network • Inter-site Cloud Coordination • PTN-based transmission • Based on TDD channel reciprocity • Apply CoMP JT at Rel. 8 and 9 in advance of LTE FDD

Background

Main Results With inter-site DL CoMP:

• Probability of throughput less than 2M drops from 8% to 1%, and less than 4M drops from 20% to 8% • The throughput of the 5% users with the poorest experience is improved by 300%, and that of the 10% users with the poorest experience is improved by 100%

The test results verified that the DL CoMP could decrease inter-site interference and improve user experience effectively.

Achievements in TD-LTE Test Solutions Conformance Toolset Supports VoLTE and LTE-Advanced

Simplified Envelope Tracking Test System

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.

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/Q-signal. 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.

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.

International TDD/FDD VoLTE Calls Demonstrated between China and South Korea

First Demonstration of CSFB International Voice Roaming

08

On 13th Nov 2013, cross-border 4G VoLTE HD audio and video call between China Mobile (TD-LTE) and SK Telecom (LTE FDD) was successfully dialed in Chengdu, China, which turned out a milestone to global 4G development. By introducing VoLTE HD coding mode, it realized end-to-end full IP voice technology. It also marked a huge breakthrough in China’s leading TD-LTE technology in voice solutions. Thus, China stepped into a new 4G era with High-Definition audio and video communication.

On 4th Dec 2013, SCFA Strategic Cooperation Summit among China, Japan and South Korea was held in Seoul, South Korea. The first CSFB voice roaming call was dialed between China Mobile (TD-LTE) and KT (LTE FDD) with TD-LTE smart phone. During the call, user experienced clear and smooth call quality, which verified seamless and consecutive characteristics of 4G voice roaming. And the TD-LTE smart phone used in this demonstration could also provide 4G data roaming service under KT’s commercial LTE FDD network. This demonstration is a remarkable progress for SCFA LTE and Global Roaming Call Team, and effectively broadened TDD VoLTE industry alliance.

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.

Successfully Demonstrated International HD Voice and Video Calls

2013 GTI Ad Hoc Seminar: Promoting the Maturity of 3.5GHz Industry Chain

3.5GHz Demonstration

Attendees

Attending delegates including government officials, TD-LTE related operators and vendors. Entrepreneurs introduced their approaches toward TDD applications in 3.5GHz through lectures and technology demonstration. SoftBank Mobile builds the world's first 3.5GHz TDD LTE Advanced trial network in Ginza, the most densely populated area in Tokyo, and conducted a car demonstration to testify practical application of TD-LTE Advanced technology in the 3.4-3.6GHz band. The network showed the support for max download speeds by making use of cutting-edge LTE-A technologies like Carrier Aggregation (CA), Coordinated Multi-Point (CoMP) and Cloud BB (Baseband). By 2015 in Japan, further spectrum from 3.4 to 3.6GHz is expected to be allocated for introducing commercial 4G networks. Globally speaking, more 3.5GHz spectrum is expected to be released to promote the development of mobile broadband services using high spectrum bands.
