Update ARIB Activities on IMT Standardization
Kohei SATOHManaging Director, ARIB
Global Standards Collaboration (GSC) GSC-15
Highlight of Current Activities (1)
The Advanced Wireless Communications Study Committee (ADWICS) is conducting technical studies on advanced wireless communication systems in cooperation with other related international/domestic organizations and is contributing to their international standardization activities
ADWICS constitutes following three subcommittees• IMT Partnership Subcommittee (3GPPs)• IMT-Advanced Subcommittee (ITU-R WP5D)• BWA Subcommittee (WiMAX, XGP, etc.)
2
Highlight of Current Activities (2)
The IMT-Advanced Subcommittee conducts technical studies on IMT-Advanced and promotes its standardization through contributions to ITU-R and other activities
The Radio Interface Technology Study Group and its Evaluation Group established under the IMT-Advanced Subcommittee prepared two draft proposals based on the IEEE802.16m and 3GPP LTE-Advanced for IMT-Advanced radio interface technology, and they were submitted to the 6th meeting of ITU-R WP5D through Japan’s national process
ARIB Evaluation Group was actively participated in IMT-Advanced evaluation activities to cooperate with other Independent Evaluation Groups through activities such as ITU-R Correspondence Groups and workshops/coordination meetings
3
Strategic Direction
ARIB will contribute to form the consensus building of IMT-Advanced, take decision on IMT-Advanced, and develop the Preliminary Draft New Recommendation on “Detailed radio interface specifications for IMT-Advanced [IMT.RSPEC]”
ARIB will also contribute to develop the Preliminary Draft New Recommendation/Report on “Analysis and assessment of global broadband wireless services and marketplace for IMT [IMT.UPDATE]”
4
Challenges
With the objective of forming consensus for
IMT-Advanced and finalizing Preliminary Draft
New Recommendation [IMT.RSPEC], ARIB will
exchange information and views and
coordinate with other PSOs or other related
groups through ITU-R WP5D, 3GPP and other
regional activities such as APT Wireless Forum
and CJK Standards meeting
5
Next Steps/Actions
ARIB will contribute to finalize the Preliminary Draft New Recommendation [IMT.RSPEC] in the 10th meeting of ITU-R WP5D
ARIB will also contribute to develop the Preliminary Draft New Recommendation/Report [IMT.UPDATE]
6
Proposed Modification of Resolution GSC-14/01
Considering recent activities in ITU-R WP5D, 3GPP, PSOs and others on IMT-Advanced, Resolution GSC-14/01 (Continuing Cooperation on IMT Standardization) should be updated and modified as follows:To update “Recognizing part” as appropriateTo add issues on the Preliminary Draft New
Recommendation [IMT.RSPEC] and Preliminary Draft New Recommendation/Report [IMT.UPDATE] in “Resolves part”

modifications of Resolution GSC-14/01 Summary (to be updated)
• PSOs updated their regional activities on IMT standardization.• The importance of cooperation on IMT standardization was emphasized in their
contributions.• Update to the GSC-14 Resolution on IMT Standardization is recommended in order to
include the current activities of 3GPP, ITU-R WP 5D and other PSOs. Resolution (to be updated)
• A drafting group will be set up to discuss with updating the Resolution GSC-14/01 on Continuing Cooperation on IMT Standardization

Recognizing:a) that Resolution ITU-R 56 describes a naming scheme for International Mobile
Telecommunications whereby “IMT-Advanced” applies to those systems, system components, and related aspects that include new radio interface(s) that support the new capabilities of systems beyond IMT-2000;
b) that Resolution ITU-R 57 outlines the essential criteria and principles that will be used in the process of developing the Recommendations and Reports for IMT-Advanced, including Recommendation(s) for the radio interface specification;
c) that ITU-R Study Group 5 and ITU-T Study Group 13 are continuing studies on IMT (encompassing both IMT-2000 and IMT-Advanced);
d) that ITU-R Study Group 5 has initiated a process for the development of terrestrial radio interface technologies that will meet the technical and operational requirements of IMT-Advanced;
e) that core network(s) are increasingly becoming access technology agnostic;f) that IMT and other rapidly emerging wireless broadband access technologies will make high-
speed wireless access services available where this was not previously possible, thereby enabling access to advanced telecommunication, computing and entertainment services and capabilities, not only for urban but also for rural and other low density environments;
g) that WRC-07 identified some additional spectrum for the implementation of IMT systems; h) that work on evolution of the radio technologies may converge to use similar techniques; andi) that there are related international, regional and national research activities in this area.
Continuing Cooperation on IMT Standardization
Resolution GSC-14/01 on IMT Standardization (1)
16
Resolves:1) to encourage 3GPP, 3GPP2, IEEE, Participating Standards Organizations
(PSOs) and others to continue to work on enhancing the IMT standards as an essential part of future telecommunication, computing and entertainment standards;
2) to encourage the harmonization of candidate proposals for the radio interface 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;
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 encourage the Task Force under the GRSC to actively help in the exchange of information and views mentioned in 4), with the goal of consensus building; and
6) to review this Resolution at future GSC meetings as required.
