Highlight of Current ActivitiesHighlight 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 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 AWG, CJK IMT WG meeting, etc.).

GSC16-GRSC9-04


Strategic DirectionStrategic Direction

The Task Force should be encouraged to actively help in the exchange of information and views with the goal of approval of the Draft New Recommendation on “Detailed radio interface specifications for IMT-Advanced [IMT.RSPEC]” in the Radiocommunication Assembly 2012 (RA-12).

The Task Force should actively support that a new agenda item on IMT spectrum issues for the World Radiocommunication Conference 2015/16 (WRC-15/16) will be adopted in the WRC-12.

Development of IMT-Advanced Radio Interface– Review to access compliance with minimum requirements (Step 6);

• Step 6 of IMT-Advanced development process was commenced in the 8th meeting of WP5D;• Between 8th and 9th meetings of WP5D, there was no contribution received on intermediary conclusion reached

in the 8th meeting based on review of the all final evaluation reports with a focus on technical aspects; and• Therefore, it was agreed that all six technical proposals met all minimum requirements specified by ITU and the

Step 6 of IMT-Advanced development process was completed.

– Consideration of evaluation results, consensus building, and decision (Step 7);• As a result of the consensus building in ITU-R among the six technology proposals, the following two groupings

are agreed by ITU-R:– The RITs and SRITs proposed in IMT-ADV/6(Japan), IMT- ADV/8(3GPP OPs) and IMT-ADV/9(China) are grouped

into the technology identified in ITU as “LTE-Advanced”, developed by the Third Generation Partnership Project (3GPP) , for Step 7 and subsequent IMT-Advanced development; and

– The RITs proposed in IMT-ADV/4(IEEE), IMT-ADV/5(Japan) and IMT- ADV/7(TTA) are grouped into the technology identified in ITU as “WirelessMAN-Advanced”, developed by IEEE, for Step 7 and subsequent IMT-Advanced development.

– The following conclusions have been reached in ITU-R in consideration of IMT-Advanced process for Steps 4 through 7;

• Both “LTE-Advanced” and “WirelessMAN-Advanced” are acknowledged to individually satisfy the requirements of Resolution ITU-R 57 for the required number of the test environments. These requirements are specified in Report ITU-R M.2133; and

• Consequently, both “LTE-Advanced” and “WirelessMAN- Advanced” are accepted for inclusion in the standardization phase of the IMT-Advanced process and should proceed to Step 8.
