Workshop on IMT Advanced

Workshop on IMT Advanced to be held in Korea on October 7th

Purpose of Workshop to provide common understanding of the process for IMT-Advanced standardization including

technical requirements and evaluation guidelines. In particular, it would enable those not directly involved WP5D works to understand IMT.TECH, IMT.EVAL and process better.

to observe current and future development aspects of IMT-Advanced Radio Interface Technology

to facilitate possible proponents for consensus building among the possible candidate IMT-Advanced RITs/Set of RIT

to share IMT-Advanced market and regulatory aspects for the introduction of the IMT-Advance

How WP5D has addressed the needs of developing countries

presentations from regional representatives(ASMG, ATU, APT, CITEL, CTU, CEPT and RCC)

Correspondence Group formed to work out detailed agenda A tentative agenda has been proposed

RIT proponents will be asked to do a presentation

3GPP2 should consider making proposal at the workshop

M.1457 Revision 9

All 6 IMT-2000 technology Radio Interfaces submitted their intention to update to Revision 9

IMT-2000 CDMA MC stated their intention to include a TDD component TIA asked to provide information on how they would incorporate a TDD component in their update

Question as to whether all SDOs need to agree to have a TDD component as an update and not a new radio interface for CDMA-MC – SDOs need to discuss – SDOs need to provide Letters of Conveyance.

OFDMA TDD WMAN stated their intention to include a FDD component

France commented that the new TDD and FDD components may have to be new Radio Interfaces and not just updates to existing Interfaces No discussion at this meeting as to whether these will be new Radio Interfaces

Final submittals for Revision 9 not due until 1st Quarter 2009

It is expected that more discussion will ensue at the next two WP5D meetings

18

M.1580/1581 – Emission Requirements for IMT-2000

It was agreed that M.1580/1 would be finalized at the next WP5D meeting in Octovber

Contributions for updates to M.1580/1 received from 3GPP, 3GPP2 and WF Updates were included into the working document

No agreement as yet on the scope of M.1580/1 Should contain frequency band specific information of M.1457 parameters to provide an easy

access for those administrations that need guidance on “generic unwanted emission characteristics parameters”

Should contain necessary technical parameters in relation to global circulation of terminals

General agreement that ACS values should not be included

General agreement that ACLR is used for sharing studies but one administration stated that they were used for more than just sharing studies

Meeting agreed to Request views from Administrations for the next WP5D Meeting Regarding the proposed “removal of ACLR from M.1580/81 and to put it in another recommendation (e.g. M.1457 or a new recommendation incorporating material from report M.2039) and in the individual sharing studies”.

On whether there is any other usage of “ACLR” apart from sharing studies

Definition of the parameter “ACLR”

On the need for further/other parameters, Proposals for the change of the scope of Rec.1580/81
