Background

GSC Task Force on IMT standardization created under the GRSC by Resolution of GSC-12 (Resolution GSC-12/01)

Activities were expected to be carried out during the ITU-R WP5D, 3GPP/3GPP2 and other regional meetings (e.g. CJK B3G WG meeting, TG-1 of AWF, etc.)

Objectives

To exchange information and views on candidate radio interface technologies for IMT-Advanced among PSOs allowing for efficient, effective and timely development of the IMT-Advanced standard

4

Standardization of IMT-Advanced in ITU-R WP5D (1)

• General– WP8F agreed draft Resolution on Principle for the process of development of

IMT-Advanced at its 20th Meeting (Resolution ITU-R 57)– The parts of Invitation Circular Letter for IMT-Advanced radio interface were

finalized at the 1st WP5D meeting and issued afterwards– Time schedule for IMT-Advanced standardization was updated at the 1st

WP5D meeting

• Principles for the process of development– Define minimum technical requirements and evaluation criteria– Invite proposals for candidate radio interface technologies for IMT-Advanced– Consensus building with the objective of achieving harmonization which

would have the potential for wide industry support– Reviews of minimum technical requirements and evaluation criteria, when

necessary– An ongoing and timely process when new radio interface technology

proposals emerge. Process to allow to evaluate against any version of criteria in force

- Issuance of Invitation Circular Letter -

• In February 2008, WP5D completed Main body, Annex 1, Annex 2 and Annex 8 of proposed Invitation Circular Letter that includes process and schedule of IMT-Advanced radio interface development

• Circular Letter which contains the parts mentioned above was issued on 7th March 2008

IMT-Advanced Subcommittee under the Advanced Wireless Communications Study Committee is conducting technical studies on IMT-Advanced and promotes its standardization through contributions to ITU-R and other activities

Considering recent activities in ITU-R WP5D, 3GPPs and other organizations, Radio Interface Technology Study Group and IMT-Advanced Evaluation Group were established in May 2008 under the IMT-Advanced Subcommittee– Radio Interface Technology Study Group will prepare draft proposal

of IMT-Advanced radio interface technology – Proposal is supposed to be submitted to ITU-R through Japan’s

national process– It is anticipated that Study Group will start with discussion on the

principle of preparing the proposal– Activities in the IMT-Advanced Evaluation Group may include self-

evaluation, endorsement of other’s evaluation and/or evaluation of other proposed technologies

ATIS interfaces with ITU both via the US Administration and also directly as a Sector Member

ATIS intends to be fully engaged in the development of IMT-Advanced technologies.

The primary contact for IMT-Advanced is the Wireless Technologies and Systems Committee (WTSC)

A large number of the member companies of WTSC are working on the IMT-Advanced issues through 3GPP

ATIS intends to get engaged in the evaluation process after the candidate IMT-Advanced technologies are submitted to ITU-R WP 5D

ATIS intends to collaborate with other PSOs for IMT-Advanced technology evaluation

Ministry of Information Industry (MII) established IMT-Advanced Promoting Group in 2007 to strength the cooperation between R&D and standardization, operators and manufacturers, and to facilitate international communication and cooperation towards IMT-Advanced – IMT-Advanced Promoting Group comprises of five working groups:

Spectrum Working Group, Requirements Working Group, Technologies Working Group, Standards Working Group and IPR Working Group

After WRC07, CCSA has launched many project related to spectrum, including co-exist and spectrum arrangement– TC5 WG6 is responsible for these projects

Recent Activities on IMT-Advanced in CCSA

11

Recent Activities on IMT-Advanced in ETSI

ETSI has established an open ad hoc group (under the Chairmanship of the Director-General) to handle the ETSI role within ITU-R IMT-Advanced Process.

ETSI has already declared that the technologies being developed within 3GPP (i.e., LTE-Advanced) will form the basis of an ETSI submission to the IMT-Advanced Process.

Discussion continues within ETSI on the detailed steps that will need to be taken with respect to IMT Advanced (e.g., whether to propose additional technologies, evaluation of candidate technologies and consensus building).

• TIA, through the U.S Administration, and its member companies are actively involved with ITU-R WP5D and its work on IMT-Advanced

• TR-45.3 and TR-45.5, TDMA-SC and cdma2000 Radio Interface Groups respectively, are responsible for work on IMT-Advanced– TR-45.3

• Evaluate Radio Interface Technology submission for IMT-Advanced jointly with ATIS WTSC RAN Group

– TR-45.5• Developed comments on the IMT-Advanced requirement (IMT.TECH) document• Developed comments on the IMT-Advanced Evaluation Methodology (IMT.EVAL)• Currently evaluating, assessing and consolidating technology proposals• Evaluate Radio Interface Technology submission for IMT-Advanced based on

output from the 3GPP2 Workshop – Future Directions and IMT-Advanced

Mobile Communications Technical Committee for IMT-Advanced was established at the end of 2007 to perform the standardization on mobile communications systems in cooperation and coordination with other related institutions in Korea and overseas

IMT-Advanced Project Group, IMT-WiBro Project Group, and Evaluation Project Group were established in Jan 2008 under the Mobile Communications Technical Committee– IMT-Advanced Project Group will prepare draft proposal of IMT-

Advanced radio interface technology based on 3GPP-LTE-advanced– IMT-WiBro Group will prepare draft proposal of IMT-Advanced radio

interface technology based on IEEE-802.16– Proposals are supposed to be submitted to ITU-R through Korea’s

national process– Evaluation Group’s activities may include self-evaluation,

endorsement of other’s evaluation and/or evaluation of other proposed technologies

Next Steps/Actions

The Task Force proposes that GSC endorses the continuation of the IMT Task Force

to exchange information and views on candidate radio interface technologies for IMT-Advanced

and requests its PSOs to review their

national/regional activities and to report on their progress at the next GSC meeting

15

Proposed modification of Resolution GSC-12/01

Considering recent activities in ITU-R WP5D, 3GPP/3GPP2, PSOs and others on IMT-Advanced, Resolution GSC-12/01 (Continuing Cooperation on IMT Standardization) should be updated.

2) to encourage the harmonization of candidate proposals for the radio transmission technologies for IMT and related networking standards;

3) to invite 3GPP, 3GPP2, PSOs and others to take care of the evolution of the current systems and the long-term evolution for such systems taking into account copyrights, working procedures, IPR aspects etc. and report to the next meeting for review; and

4) to exchange information and views on candidate radio interface technologies for IMT-Advanced among PSOs allowing for efficient, effective and timely development of the IMT-Advanced standard;

5) to create a Task Force under the GRSC to be available to exchange information and views mentioned in 4), if needed; and

6) to review this Resolution at future GSC meetings as required.

A major objective of the Asia-Pacific Telecommunity Wireless Forum (AWF) is to promote new wireless applications in the Asia-Pacific region and in this regard:– AWF Task Group 1 (TG1) reviews the activities on the future

development of IMT-2000 and IMT-Advanced developed in the relevant ITU-R Working Parties

– TG1 develops views on issues arising from the review of the service aspects and the progress of the enhancement and evolution of IMT-2000 and IMT-Advanced by these ITU-R Working Parties and ascertains their applicability to the region

– The AWF Spectrum Working Group (SWG) identifies the spectrum requirements for new radio technologies and develops plans for harmonized spectrum usage for radiocommunication systems in the region

– The SWG also develops optimum sharing methodologies between radio services and methods ensuring compatibility between systems
