Association of Radio Industries and Businesses
(ARIB)
Submission Date:
July 8, 2008
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
2
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
4
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
5
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
6
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
