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 • 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…
