22 ITU-R Liaison Group Report - Session #75 Closing Plenary Takashi Shono Chair, ITU-R Liaison Group IEEE WG Session #75 Bangkok, Thailand, September 2011

3 Agenda for the Week 1) Introduction, approval of the agenda 2) Review and follow workplan of L /0026r1 3) Work Items: 3-1)Develop and finalize transposition references 3-2)Develop M Meeting X+2 contribution 3-3)Prepare for/hold/review the CRS tutorial 4) Review inputs/liaisons, and prepare responses and any other output documents to external organizations as necessary 5) Update workplan 6) Approve all outgoing documents 7) Other business

4 Outcomes of Session #75 (1/2) Per Workplan Develop and finalize transposition references − L /0057r1 – Transposition References Develop M Meeting X+2 – Ask for support from experts on h and m (Refer to temp/L _0059annex2d0) − L /0059d0 - [Draft Contribution to WP 5D] IMT-2000 OFDMA TDD WMAN submission toward revision 11 of Recommendation ITU-R M.1457 (Meeting X+1)

5 Outcomes of Session #75 (2/2) Beyond Workplan Prepare for/hold/review the CRS tutorial − Refer to Slides #6 & #7 Update ITU-R LG workplan − L /0026r2 - IEEE ITU-R Liaison Group Workplan

6 Highlights of CRS Tutorial (1/2) Contribution (IEEE C /0008) was presented – Agenda: Expectation for Cognitive Radio – Background, concept, definition and examples of CRS Standardization activities in ITU-R – WP 1B: Regulatory study (towards WRC-12) – WP 5A: Technical study on LMS except IMT (to develop ITU-R Report) – WP 5D: Technical study on IMT system (to develop ITU-R Report) Research on Cognitive Radio in KDDI R&D Laboratories – Heterogeneous network among LTE, WiMAX and Wi-Fi Discussions for future study on CRS in WG – See Slide #7

7 Highlights of CRS Tutorial (2/2) Discussions for future study on CRS in WG Operators’ Motivation UQ/KDDI are interested in heterogeneous network deployment (LTE, WiMAX and Wi-Fi) to accommodate exponential growth of user traffic Clarifications The technical report on “Hierarchical networks” already includes the scenario of heterogeneous network of IEEE and , where 3GPP radio interfaces are not precluded from the scope Any discussion on multi-network interworking in the WG is expected to be consistent with studies on similar discussion happening in the WiMAX Forum, and it may be efficient to cooperate with them to study the issue Possible Way Forward To clarify the issues and what we should do in the WG to meet operators’ need for heterogeneous network To consider contributing to ITU-R WP 5A so that the expected scenario is captured in the Report ITU-R M.[LMS.CRS2]
