Highlight of Current Activities (1)

• 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

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 IEEE802.20 referring to
  relevant international standards.

Strategic Direction
Reorganization of IMT-Advanced Subcommittee

• 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

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 Japans 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 Forces activities
