TD-SCDMA & TD-LTE Standard and Industry in China

1. TD-SCDMA & TD-LTE Standard and Industry in China Ke Wang, CCSA Global Standards Collaboration (GSC) GSC-15

2. Highlight of Current Activities • Continue Standard evolution in 3GPP • TD-SCDMA/TD-LTE Rel-9 in 3GPP was finished by the end of 2009. • Further investigation of TD-SCDMA evolution in 3GPP Rel-10, such as MC HSUPA, MU-MIMO and distributed antenna etc. • TD-LTE-Advanced is also working under Rel-10 WI, and target to be finished at end of 2010. • Working closely with global partners in 3GPP.

3. Highlight of Current Activities • Continue Standard evolution in CCSA • The TD-SCDMA Industry standard Phase 4 has just been finished by Aug, 2010. • TD-SCDMA further enhanced and optimized is under study in CCSA TC5 WG9. • TD-LTE technique report has been started from March, 2010.

4. Highlight of Current Activities • TD-LTE-Advanced submission to ITU-R • TD-LTE-Advanced was submitted to WP5D#6 on Oct, 2009 as IMT-Advanced candidate RIT, which is TDD RIT component of LTE-A SRIT developed in 3GPP. Furthermore, TD-LTE-A description templates and self evaluation report submitted to ITU-R are consistent with 3GPP’s final submission. • ChEG is working on evaluation of IMT-Advanced candidate submissions in China. • More detailed information of ChEG can be found in slides 15-17. • Preliminary evaluation results from ChEG was submitted to WP5D#7 on Feb, 2010. • Final evaluation report was submitted to WP5D#8 on Jun, 2010. • Check evaluation assumption and results with other EGs.

5. Highlight of Current Activities • TD-SCDMA commercial network in China • TD-SCDMA Phase 4 network will start to build on the second half of 2010 by China Mobile, and target to cover 330 cities in China. • The TD-SCDMA subscribers have already exceed 10 million by Jun 30, 2010(Data from MIIT). • TD-LTE Test in China • The TD-LTE test was organized by CATR of MIIT. • Phase I: POC • Phase II: technical test(IOT, indoor, outdoor) • Phase III: Scale trial

6. Strategic Direction TD-SCDMA Standard evolution Phase 1 Phase 2 Phase 3 Base on CDMA Base on OFDM LTE-Advanced LTE version Basic Version Enhanced version 3GPP（R5-R10） TD-HSPA TD-MBMS TD-HSPA+ 3GPP（R10/R11…） TD-LTE-Advanced 3GPP（R8/9） TD-LTE 3GPP（R4） TD-SCDMA 2010-? 2006--2010 2001--2003 2004---2010

7. Challenges • Large-scale TD-SCDMA network cover the whole country is approaching. • The whole network optimized is considered as a big challenge. • Interworking with GSM. • Enough attractive application to final customer is need to be developed. • Much more international cooperation in marketing is expected.

8. Next Steps/Actions • Complete TD-SCDMA/TD-LTE-Advanced work in 3GPP Rel-10 by the end of 2010. • Issue the TD-SCDMA industry standard phase 4 and complete the TD-LTE technique report in CCSA. • Complete TD-LTE-Advanced evaluation, consensus building and develop the radio interface Recommendation in ITU-R WP5D. • Start the TD-SCDMA commercial network Phase 4 building and continue the whole network optimized. • Continue TD-LTE test in China. • Continue to work cooperatively with external organizations.

9. Proposed Resolution [optional] • N/A.

15. ChEG revived at the end of 2008 for evaluation of IMT-Advanced candidate RITs. • There are 13 members in ChEG including operators, vendors, research institutes and universities. • ChEG participated ITU technical evaluation events • IMT-2000 candidate evaluation in 1999, • WiMAX evaluation in 2007 • Output • Standard organizations • ITU-R • Website: http://cheg.ccsa.org/

16. ChEG Task • Calibrate among members of ChEG to achieve consistent results. • During self evaluation phase, participate self evaluation of standard organizations (3GPP, IEEE ) in the name of members • During third-party evaluation phase, evaluate candidate RITs in the name of ChEG • Contribute to standard organizations (3GPP, IEEE ) to facilitate the harmonization in the name of members • Contribute to ITU-R WP5D • evaluation report for candidate RITs during evaluation phase
