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 Telecommunications2000 (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

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 + selfevaluation or proponent’s 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)

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

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
