1. CJK IMT 28 Xi’an, China 2-3 Jun. 2011 CJK IMT 28, Xi’an, China 1/4 CJK-IMT28-012 Possible Contribution to 11th Meeting of WP5D ~ Related to Updating of Questions ITU-R 229-2/5 and ITU-R 77-6/5 ~ TANNO, Motohiro (tanno@nttdocomo.co.jp)

2. 2/4 CJK IMT 28, Xi’an, China Introduction This contribution provides preliminary draft texts for updating Questions ITU-R 229-2/5 and ITU-R 77-6/5 both assigned to WP 5D. Such updating was originally requested in Document 5D/712 (Chairman, SG5), and contributions have been invited at the past meetings of WP 5D, specifically by the Chairman of WG General Aspects.

3. 3/4 CJK IMT 28, Xi’an, China Consideration on Question ITU-R 229-2/5 Question ITU-R 229-2/5 “Future development of the terrestrial component of IMT” One understanding may be that most of the assigned questions in Part A of “decides” have been completed by adoption of Recommendation ITU-R M.[IMT.RSPEC], and future work could focus on the questions in Part B.  Part A – Future development and ongoing enhancement of the terrestrial component of IMT  Part B – Long-term development of IMT However, we would suggest to retain most of the questions in Part A, noting that “Future development and ongoing enhancement” is still needed for current IMT systems (for both IMT-2000 and IMT-Advanced). Therefore, the proposed updating does not contain major deletions or additions of the questions in “decides” part, but proposes refinement of the text.

4. 4/4 CJK IMT 28, Xi’an, China Consideration on Question ITU-R 77-6/5 Question ITU-R 77-6/5 “Consideration of the needs of developing countries in the development and implementation of mobile radiocommunication technology” There have been limited outputs in the past although the Question has identified many points for consideration and items to which attention should be given in carrying out the studies. We have attempted to simplify the text, merging the existing 3 questions in “decides” part into one comprehensive question and reducing the number of items under “considering” part and the associated NOTEs. Recognizing the importance of this Question, the specific elements to be addressed for developing countries are retained as far as possible.

5. 5/4 CJK IMT 28, Xi’an, China Summary Preliminary texts for updating are provided in the Attachments of the contribution for both Questions.
