Activities of ARIB on IMT Standards Kohei SATOH Association of Radio Industries and Businesses (ARIB) DOCUMENT #:GSC13-Plenary-60 FOR:Presentation SOURCE:Kohei SATOH (ARIB) AGENDA ITEM:6.1 Submission Date: July 8, 2008

2 Advanced Wireless Communications Study Committee (ADWICS) was established in April 2006, through extending the scope of former IMT-2000 Study Committee ADWICS constitutes following three subcommittees to perform the technical studies on advanced wireless communication systems in cooperation with other related international/domestic organizations and to contribute to their international standardization activities –IMT Partnership Subcommittee –IMT-Advanced Subcommittee –BWA Subcommittee Highlight of Current Activities (1)

3 Highlight of Current Activities (2) IMT Partnership Subcommittee –Operate 3GPPs as one of an Organizational Partner –Prepare contribution to 3GPPs on national regulatory requirements aspects –Downstream activities of the specification developed by 3GPPs for ARIB Standards IMT-Advanced Subcommittee –Conduct technical studies on IMT-Advanced –Promote its standardization through contributions to ITU-R and other activities BWA Subcommittee –Produce national standards for WiMAX, Next Generation PHS and IEEE referring to relevant international standards.

4 Strategic Direction 3GPPs and other organizations are in a stage to start to develop candidate radio interface specifications for IMT-Advanced Opinions to shift resources to those specification development activities Proposal to establish Radio Interface Technology Study Group by Circular Handling WG Proposed reorganization was approved in May 2008 in the Steering Committee of ADWICS Reorganization of IMT-Advanced Subcommittee

5 Challenges Establish “Radio Interface Technology Study Group” –Study Group will prepare draft proposal of radio interface technology for IMT-Advanced –Proposal is supposed to be submitted to ITU-R through Japan’s national process –It is anticipated that Study Group start with discussion on the principle of preparing the proposal Establish “IMT-Advanced Evaluation Group” –Activities may include self-evaluation, endorsement of others’ evaluation and/or evaluation of other proposed technologies

6 Next Steps/Actions Radio Interface Technology Group will develop Japanese draft proposal of radio interface technology for IMT-Advanced IMT-Advanced Evaluation Group will exchange information and views and coordinate with other PSOs through ITU-R WP5D, 3GPPs and other regional activities

7 Proposed Update of Resolution GSC-12/01 Considering recent activities in ITU-R WP5D, 3GPPs, PSOs and others on IMT-Advanced, Resolution GSC-12/01(Continuing Cooperation on IMT Standardization) should be updated as follows: –To update “Recognizing part” as appropriate –To revise “Resolves 5)” as below 5) To encourage exchanging information and views towards consensus building on radio interface technologies for IMT-Advanced through GSC IMT Task Force’s activities
