current activities in ccsa
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
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
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
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…
