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 IMTAdvanced, 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 appropriate
To add issues on the Preliminary Draft New
Recommendation [IMT.RSPEC] and Preliminary
Draft New Recommendation/Report [IMT.UPDATE]
in “Resolves part”

Resolution GSC-14/01 on IMT
Standardization (1)
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 IMTAdvanced;
e)
that core network(s) are increasingly becoming access technology agnostic;
f)
that IMT and other rapidly emerging wireless broadband access technologies will make highspeed 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; and
i)
that there are related international, regional and national research activities in this area.

6)
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;
to encourage the harmonization of candidate proposals for the radio interface
technologies for IMT and related networking standards;
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;
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;
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
to review this Resolution at future GSC meetings as required.
