Recent Activities on IMT-Advanced
in ARIB
 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 IMTAdvanced 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 selfevaluation, endorsement of other’s evaluation and/or evaluation of
other proposed technologies
8
Recent Activities on IMT-Advanced
in ATIS
 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 IMTAdvanced 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
9
Recent Activities on IMT-Advanced
in CCSA
 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
10
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).

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 IMTAdvanced 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

Activities of the Asia-Pacific Telecommunity
Wireless Forum (AWF)
 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 IMT2000 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
