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

Global Standards Collaboration (GSC)
GSC-15
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.
2
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.

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.

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

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.
7
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 TDLTE 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.

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
