  1. CJK-IMT28-036 How to make the way forward for Q241-1/5 in ITU China Communications Standards Association Qingguo FENG (qingguo.feng@nokia.com) CJK IMT #28, Xi’an China, 2-3 June 2011

  2. QUESTION ITU-R 241-1/5Cognitive radio systems in the mobile service • Whatis the ITU definition of cognitive radio systems? • What are the closely related radio technologies (e.g. smart radio, reconfigurable radio, policy-defined adaptive radio and their associated control mechanisms) and their functionalities that may be a part of cognitive radio systems? • What key technical characteristics, requirements, performance and benefits are associated with the implementation of cognitive radio systems? • What are the potential applications of cognitive radio systems and their impact on spectrum management? • What are the operational implications (including privacy and authentication) of cognitive radio systems? • What are the cognitive capabilities that could facilitate coexistence with existing systems in the mobile service and in other radiocommunication services, such as broadcast, mobile satellite or fixed?

  3. QUESTION ITU-R 241-1/5 (Cont.)Cognitive radio systems in the mobile service • What spectrum-sharing techniques can be used to implement cognitive radio systems to ensure coexistence with other users? • How can cognitive radio systems promote the efficient use of radio resources? Notes • Former Question ITU-R 241-1/8 • Question on should be brought to the attention of SG1, 4, 6 and 9. • That the results of the studies should be included in one or more Recommendations, Reports or Handbooks • That the studies should be completed by the year 2010. • Category: S2

  4. The Progress in ITU-R • WP1B had finished the definition of CRS, referring Report ITU-R SM.2152 • WP5A is the responsible group for the technical work on CRS in the LMS, concentrating mainly on addressing this Q241-1/5. Six meetings had been held. • AReport ITU-R M.[LMS.CRS] has been drafted to fill the study results. • Some items has been finished very clearly, the others still need to be studied further. • LMS.CRS is scheduled the completion at WP5A#8, November 2011. • From current view, it’s impossible to make every item clear in that timeframe. • Conclusion • Good progress has been made in ITU-R for Q241-1/5. • It’s necessary to continue the study and address the outstanding parts.

  5. Way forward • Under the agreement that the work in ITU-R for CRS in LMS needs to continue, it should be discussed • What parts of current Question Q241-1/5 have not yet been covered? • Or are additions needed? • Is it necessary to make a mild modification to Q241-1/5 accordingly and to propose preparation of a new report? • If yes, what should be reflected in a new report? • Update example attached. • Is it necessary for CJK to contribute something on this issue?

  6. Thanks!
