Fostering worldwide interoperability 2 Geneva, July 2009 GSC Task Force on IMT standardization was created under the GRSC by Resolution of GSC-12 (Resolution GSC-12/01). 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. Activities would be expected to be carried out during the ITU-R WP5D, 3GPP/3GPP2 and other regional meetings (e.g., CJK B3G WG meeting, IMT-WG of AWF, etc.). Highlight of Current Activities

Fostering worldwide interoperability 3 Geneva, July 2009 The Task Force should be encouraged to actively help in the exchange of information and views with the goal of consensus building which is performed with the objective of achieving global harmonization and having the potential for wide industry support for the radio interfaces of IMT-Advanced. Activities of the Task Force should be continued to develop detailed specifications of the radio interfaces for IMT-Advanced. Strategic Direction

Fostering worldwide interoperability 4 Geneva, July 2009 Candidate radio interface technologies (RITs) will be evaluated in the Step 4 of IMT-Advanced radio interface development process. The ITU-R membership, standards organizations, and other organizations were invited to proceed with the evaluation. 12 evaluation groups were registered with the ITU-R. Coordination among evaluation groups is strongly encouraged to facilitate comparison and consistency of results, to assist ITU-R in developing an understanding of differences in evaluation results achieved by the independent evaluation groups and to form some preliminary consensus on the evaluation results. Pre-coordination or discussions towards coordination should be carried out through the Task Force activities. Challenges

Fostering worldwide interoperability 5 Geneva, July 2009 The Task Force proposes that GSC endorses the further continuation of the IMT Task Force to exchange information and views with goal of consensus building for the radio interfaces of IMT- Advanced, 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. Next Steps/Actions

Fostering worldwide interoperability 6 Geneva, July 2009 Considering recent activities in ITU- R WP5D, 3GPP/3GPP2, PSOs and others on IMT-Advanced, Resolution GSC-13/01 (Continuing Cooperation on IMT Standardization) should be updated. Proposed Modification of Resolution GSC-13/01
