CCSA Standardization Activities on Cognitive Radio System Document No: GSC16-GRSC9-20 Source: CCSA Contact: Longming ZHU GSC Session: GRSC-9 Agenda Item: 4.2 CCSA Standardization Activities on Cognitive Radio System Longming ZHU CCSA （ZTE）

Current Activities in CCSA Two Working Groups studies on CRS inside CCSA TC5 WG 8 (Frequency) WG6 (Wireless new technology). The progress of WG8 on CRS is quite faster than WG6 in CCSA, WG8 launched the research almost two years before WG6, and WG8’s meetings are arranged more frequently than WG6’s. The project in WG8 was first discussed in its 27th meeting in Nov, 2008; and initiated the work in its 28th meeting in Dec, 2008.

Current Activities in CCSA (cont.) Two sub-projects in WG8 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, the report on WRC-12 AI1.19 almost finished. Contributions will be collected during the WG8’s meeting for discussion and two documents will be updated accordingly if necessary.

Current Activities in CCSA (cont.) The report of CRS techniques aspects and relevant spectrum issues in CCSA WG8 contains the following sections: The concept of CRS Key technologies for CRS Possible deployment scenarios for CRS Technology evaluation for CRS Impacts on radio regulation and policy Suggestion and other aspects This report is a start point for the study of CRS in CCSA, and it could also be divided to sub-reports (focus on special aspect) due to the future requirement.

Current Activities in CCSA (cont.) CCSA WG8 discussed and finished the questionnaire on CRS in APT region which sent it back to the 11th AWG meeting consequently. The views on each question had been collected from academic and industry field, and discussed by the attendants during the meeting. From this questionnaire results, it is easy to understand that CCSA hold the positive view on the development of CRS.

Strategic Direction Deepen on the research on CRS Deployment scenarios Technical aspects Radio regulation and policy aspects Suitable for Chinese national condition Tri-networks convergence From academia research to industry Collaborated with the external SDOs Pay attention on WRC-12 result

Challenges For administrations For operators For vendors/manufactures Spectrum management new method No harmful interferences to primary services …… For operators Minimum change to the current system Smoothly compatible with existing wireless system Acceptable cost control(CAPEX, OPEX) QoS For vendors/manufactures Lower system complex Reconfiguration overhead CRS standardization process

Next Steps / Actions To continue CRS work in CCSA Not only in studied WG8 but also begin the research in WG6 To continue complete the report in WG8 based on input contributions To promote collaboration between academic and industry on CRS: Research projects on CRS in China: 863, National Major S&T projects… To promote collaboration among different regions on CRS standardization In ITU-R, AWG, ETSI…
