CCSA Standardization Activities on Cognitive Radio System DOCUMENT #: GSC15-GRSC-07 FOR: Presentation SOURCE: CCSA AGENDA ITEM: 4.3 CONTACT(S): yang.guang@zte.com.cn CCSA Standardization Activities on Cognitive Radio System ZTE Corporation – CCSA Global Standards Collaboration (GSC) GSC-15

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

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.

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

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

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…

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

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.
