Highlights of Current Activities (1)

• Activities on IMT-2000
• Radiocommunication Assembly (RA-07) added sixth
  terrestrial radio interface to IMT-2000 family -
  OFDMA TDD WMAN (a WiMAX derived technology)
• RA-07 approves seventh revision to Recommendation
  ITU-R M.1457 (Detailed specifications of the
  radio interfaces of International Mobile
  Telecommunications-2000 (IMT-2000)) (M.1457-7)
• RA-07 approves revision to Recommendation ITU-R
  M.1580 (Generic unwanted emission characteristics
  of base stations using the terrestrial radio
  interfaces of IMT 2000) and to M.1581 (Generic
  unwanted emission characteristics of mobile
  stations using the terrestrial radio interfaces
  of IMT-2000)
• further studies requested at RA-07 on emission
  mask and ACLR
• Sharing studies requested between OFDMA TDD WMAN
  and the other terrestrial IMT interfaces
  (results to be presented to SG 5 meeting in Nov
  2008 probably as a new Report)
• Eighth Revision of Recommendation ITU-R M.1457
  currently under approval process (following
  decisions of SG 5 in Feb. 2008)
• Work commenced on Ninth revision of M.1457 which
  should conclude in Feb. 2009

Highlights of Current Activities (2)

• RA-07 provides impetus for IMT-Advanced
• Approval of Resolution ITU-R 56
• naming scheme for International Mobile
  Telecommunications
• Approval of Resolution ITU-R 57
• Principles for the process of development of
  IMT-Advanced
• Radio Interface Technologies (RIT) to be proposed
  for IMT-Advanced shall be based on submissions
  from the ITU membership, as well as on invited
  submissions from external organizations
• Based on deliberations at WP 5D meeting (Jan.
  2008), Circular Letter 5/LCCE/2 was issued 7
  March 2008 inviting the submission of proposals
  for candidate RITs (or a set of RITs (SRITs)) for
  the terrestrial component of the radio
  interface(s) for IMT-Advanced and inviting
  participation in their subsequent evaluation

4
Strategic Direction (1)

• Initial invitation for proposals for RITs (and
  SRITs) and description of evaluation process
  (Circular Letter 5/LCCE/2)
• See IMT-Advanced website http//www.itu.int/ITU
  -R/go/rsg5-imt-advanced/
• Invitation from BR to submit candidate RITs (or
  SRITs) for IMT-Advanced
• Development of candidate RITs (or SRITs)
  satisfying a version of the minimum technical
  requirements and the evaluation criteria
  currently in-force
• Registration of evaluation groups with ITU-R
• Submission of proposals evaluation to BR,
  subsequently becoming inputs to WP 5D
• Evaluation of candidate RITs (or SRITs) by
  registered evaluation groups self-evaluation or
  proponents endorsement of evaluation submitted
  by another entity
• Assessment of proposals by WP 5D and their
  compliance with the minimum technical
  requirements
• Consideration of evaluation reports by WP 5D
• Consensus building leading to acceptance of a RIT
  (or SRIT) in the standardization phase
• Development of radio interface Recommendation(s)

5
Strategic Direction (2)

• Additional information required for the
  evaluation process (to be issued after WP 5D
  meeting in June 2008)
• Minimum technical requirements related to
  technical system performance
• Spectrum-related requirements
• Submission guidelines and a template for details
  of the submission
• Evaluation guidelines, criteria and methodology

6
Challenges

• Harmonisation of proposals
• IPR issues
• Timescales not being met
• WP structure

7
Next Steps/Actions

• Schedule for the development of IMT-Advanced
  radio interface recommendations

8
Proposed revision to Resolution GSC-12/01

• Resolution GSC-12/01 requires updating to reflect
  the results of the Radiocommunication Assembly
  (RA-07) and the World Radiocommunication
  Conference (WRC-07)
• A draft revision is contained in a contribution
  from ISACC
