中移动TD-LTE及对终端的要求
中移动2013的愿景:
1, TD-LTE going into commercial year in Y2013
2, TD-LTE developing strategy: promoteTD-LTE and FDD-LTE to synchronization, integration and global roaming
3, For data products in Y2013, CMCC willfocus on MiFi, USBD and CPE
4, for the phone, 5-10 types with CSFB andsingle SIM/dual-band
6, TD-LTE voice solution is under filed testingwith large scale
GCF 情况和进展
- All TDD bands activated:B38/B39/B40/B41
- Dual-layer beam-forming(WI-139)activated
- TP for R9 device coveringB38/B39/B40(WI-150s) ready
- TP for LTE FDD/TDD dual-modedevice(WI-151) ready
- First TD-LTE FTQ declared andready for field test

TD-LTE 终端的语音方案
CSFBtype
At now, CMCC adopted CSFB which fallback toGSM network as TD-LTE voice solution during the transition stage, the detail asthe following
- Support CSFB fallback to GSM,the approach require that R9 redirect(compatible with R8 redirect)
- Recommend to fallback toTD-SCDMA, approach require that R9 redirect(compatible with R8 redirect) and PShandover
- Support Fast-return, the terminalcan quickly return from GSM to LTE
- Support FDD-LTE CSFB whichfallback to WCDMA
Dual-standbytype
CMCC also support dual-standby terminal solution,try to verify and optimize power consumption, mutual interference and so on keyspecifications in large scale filed testing
- Type1, LTE andTD-SCDMA/WCDMA/GSM dual-standby
- Type2, LTE/TD-SCDMA andWCDMA/GSM dual-standby
