Highlight of Current Activities n GSC Task Force on IMT standardization was created under the GRSC by Resolution of GSC-12 (Resolution GSC-12/01). n An objective of the Task Force is to exchange information and views on candidate radio interface technologies for IMT-Advanced among PSOs allowing for efficient, effective and timely development of the IMT-Advanced standard. n Activities would be expected to be carried out during the ITU-R WP 5 D, 3 GPPs and other regional meetings (e. g. , IMT-WG of AWF, CJK IMT WG meeting, etc. ). 2

Strategic Direction n The Task Force should be encouraged to actively help in the exchange of information and views with the goal of consensus building for the radio interfaces of IMTAdvanced and finalization of the Preliminary Draft New Recommendation on “Detailed radio interface specifications for IMT-Advanced [IMT. RSPEC]”. n Activities of the Task Force should be continued to develop the Preliminary Draft New Recommendation/ Report on “Analysis and assessment of global broadband wireless services and marketplace for IMT [IMT. UPDATE]”. 3

Next Steps/Actions n The Task Force proposes that GSC • endorses the further continuation of the IMT Task Force to exchange information and views with goal of finalization of the Preliminary Draft New Recommendation [IMT. RSPEC] and Preliminary Draft New Recommendation/Report [IMT. UPDATE], and • requests its PSOs to review their national/regional activities and to report on their progress to the Task Force and at the next GSC meeting. 4

Proposed Modification of Resolution GSC-14/01 n Considering recent activities in ITU-R WP 5 D, 3 GPP, PSOs and others on IMT-Advanced, Resolution GSC-14/01 (Continuing Cooperation on IMT Standardization) should be updated and modified as follows: èTo update “Recognizing part” as appropriate èTo add issues on the Preliminary Draft New Recommendation [IMT. RSPEC] and Preliminary Draft New Recommendation/Report [IMT. UPDATE] in “Resolves part” 5
