CCSA Standardization Activities on Cognitive Radio System

Global Standards Collaboration (GSC) GSC-15

ZTE Corporation – CCSA

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…

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.
