2. Current Activities in CCSA
Current Studies on CRS are undertaken in Working Group 8 of Wireless Technical Committee, CCSA.
The project was first discussed in WG8’s 27th meeting in Nov, 2008; and initiated the work in its 28th meeting in Dec, 2008.
Current activities can be summarized as two sub-projects:
Technical Report for WRC12 Agenda Item (AI) 1.19
CR(S) Techniques and its relevant spectrum issues

3. Current Activities in CCSA (cont.)
The original target of the project was for the WRC12 Agenda Item 1.19.
It is believed the techniques research is necessary and critical for the AI1.19, the scope of the project extended subsequently.
Two sub-projects aimed or emphasized different aspects but have internal relation.
CRS techniques aspects and relevant spectrum issues
On regulatory and policy aspects (AI 1.19)
Two sub-projects’ life cycles are different.

4. Challenges of CRS standardization
How to transfer CRS work from academia to industry?
Concrete use cases and scenarios for CRS deployment
Tradeoff between advanced theory and industrial reality
Different environment of regulation
CRS deployment more influenced by regulation polices than other radio technologies
Common ground for consensus in standardization and scale of economy

5. Strategic directions CRS for IMT system
Intra-operator scenario
Spectrum sharing among cells in one RAN
Standard or mode handover for multi-standard/multi-mode terminal
Spectrum sharing among different RANs
Inter-operators scenario is FFS
CRS for tri-network convergence
Facilitate the Integration of telecommunications networks, cable TV networks and the Internet
Allow different operators to share TVWS band for different service requirements
Seamless coverage for different services between different networks

6. Next step To continue CRS work in CCSA
To complete Technical Report for WRC12 Agenda Item (AI) 1.19 by mid-2011.
To promote collaboration between academia and industry on CRS study
Research projects on CRS in China: 863, 973…
To promote collaboration among different regions on CRS standardization
In ITU-R, AWF…

7. Supplemental Slides 7

8. Researches on the deployment of CRS
CRS capability could improve IMT systems’ performance
Upgrading a pre-existing RAT or deploy of a new RAT to a pre-existing network
Multi-modes coexistence
Multi-standards coexistence
Optimized Resource Usage
Temporary high capacity coverage
Tri-Networks integration

9. Example: Use case of CR in IMT System
Different RATs or modes, could share the resources with CRS capabilities, including wireless resources, equipment software and hardware process resources, etc.
IMT RATs with CRS capability could utilize the TVWS resource and transfer service from different networks.
