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 WG8s meetings are arranged more
  frequently than WG6s.
• 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 WG8s
  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.

5
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

7
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

8
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 ST projects
• To promote collaboration among different regions
  on CRS standardization
• In ITU-R, AWG, ETSI
