7. Activates Initiated by MIIT since 2010.06
Technical discussion and studies began in
tens of face to face meeting,
Leading by CATR,
CATT, CMCC, Huawei, ZTE, INNOFIDEI, China Unicom, China Telecom
Extended in IMT-Advanced Promotion Group
16 entities included: Government academy, Operators, Manufactures, Colleges.
Will be studied in the Requirement, Technologies and Standard group.

8. Activates Government Project Planning
“Enhancement Technologies for Indoor/Hotspot based on LTE-A”, National Science and Technology Major Project Lead by MOST and MIIT.
CATR, CATT(Datang), CMCC, Huawei, ZTE, INNOFIDEI, Peking University, BUPT
Workshop with ERICSSON and Common Understanding
It is important to ensure that radio-access technologies in 3GPP can operate efficiently in local-area/low-mobility scenarios
LTE evolution for the low-mobility/local-area scenario
The operation on licensed spectrum with operators is necessary and has first priority . As low priority, consider it can work on unlicensed spectrum as complement.
For deployment or usage scenario, focus on operator deployment.
Workshop with Nokia/NSN and Common Understanding
Common understanding with the scenarios and requirement.
Standard development in 3GPP

10. Solutions and Plan Extended Spectrum Bands
1000 times of traffic can not be reached only be technical enhancement
Spectrum suitable for mobile is limited(<3GHz)
Indoor/Hotspot dominate the 80% of 1000
Short coverage/Low mobility requirement
Wide bandwidth/High throughput requirement
Avoid outdoor-indoor interference, easy to deployment and good performance
Extended band from cellular network to high spectrum band(>3GHz)

11. Solutions and Plan
LTE/LTE-A Based Local Area Access

12. Solutions and Plan
LTE/LTE-A Femto Enhancement

13. Solutions and Plan Others
New/Optimized PHY/MAC design for Indoor/Hotspot scenarios
Simplified RF design for cost efficient
Wide bandwidth for high speed
QoS enhancement for high speed data
L2 Optimize for data services …
