  1. CCSA Standardization Activities on Cognitive Radio System ZTE Corporation – CCSA Global Standards Collaboration (GSC) GSC-15

  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.
