Highlight of Current Activities

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, 3GPPs and other regional meetings (e.g., IMT-WG of AWF, CJK IMT WG meeting, etc.).

Strategic Direction

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 IMT-Advanced and finalization of the Preliminary Draft New Recommendation on “Detailed radio interface specifications for IMT-Advanced [IMT.RSPEC]”.

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]”.

Next Steps/Actions

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.

Six proposals based on the IEEE 802.16m or 3GPP LTE-Advanced technology were submitted for candidate radio interface technologies for IMT-Advanced at the 6th meeting of ITU-R WP5D in Dresden, Germany.

WP5D determined that each submission was “complete”, and issued acknowledgement to all proponents.• The Step 3 of IMT-Advanced development process was completed.

Following the completion of the Step 3 of the IMT-Advanced development process, WP5D initiated evaluation of the six candidate technology submissions.• Correspondence Groups were established as a tool to augment communication

and to facilitate the evaluation work of WP5D and the Independent Evaluation Groups on the candidate IMT-Advanced technologies.

The 3rd workshop on IMT-Advanced was held on 15th October 2009 in conjunction with the 6th meeting of WP5D.• Proponents of IMT-Advanced candidate radio interface technology and external

evaluation groups were invited to join and make presentations.

Activities of the Asia-Pacific Telecommunity Wireless Forum (AWF) (1)

A major objective of the Asia-Pacific Telecommunity Wireless Forum (AWF) is to promote new wireless applications in the Asia-Pacific region and in this regard:• The AWF Spectrum Working Group (WG-SPEC) identifies the spectrum

requirements for new radio technologies and develops plans for harmonized spectrum usage for radiocommunication systems in the region. Studies are proceeding on frequency arrangements for the 698-806 and 2300-2400 MHz bands.

The Correspondence Group (CG) activity on Frequency Arrangement(s) for the band 698-806 MHz is continuing, with substantial input contributions to the latest phase of that work having already been received. This correspondence work is continuing and will be reviewed and fine-tuned at a face-to-face meeting of the CG on 12 th September in Seoul. We have the objective to seek to complete the work at the 9 th meeting of AWF, using the material from the CG as the major input to the discussions.

With respect to Frequency Arrangements for the band 2300-2400 MHz, the “APT REPORT on APT Frequency Arrangement on 2300-2400 MHz for IMT/BWA (No. APT/AWF/REP-12) was adopted by the 8th meeting of AWF. It remains to be seen if there is interest in developing an APT Recommendation based on this material, and this could be a discussion point at the 9th meeting of AWF.
