  it was decided to contribute a presentation from
  AWG to the ITU-R WP 5D workshop.
• Based on this decision, this presentation is
  prepared to briefly introduce
• Overview of APT Wireless Group
• Overview of mobile communications in the
  Asia-Pacific region
• Studies on future IMT technologies being
  considered in AWG
• Other examples of research projects/programs in

Overview of APT Wireless Group

• The APT Wireless Group (AWG) is covering various
  aspects of emerging wireless systems including
  IMT to meet the upcoming digital convergence era
  in the Asia-Pacific region.
• ToR of AWG
• Share and discuss information of emerging radio
  technologies, stimulate research and development,
  and promote related telecommunication business
  within the Asia-Pacific region
• Pursue effective solutions in the Asia-Pacific
  region to meet the rapid movements towards
  digital convergence
• Provide regular channels to discuss and study
  spectrum sharing methodologies, spectrum
  harmonization and to provide advice that
  countries' can use in frequency band planning
• Develop technical and radio regulatory solutions
  based on emerging and conventional wireless
  technologies including satellite technologies to
  meet APT member's needs

AWG is Now Growing

• Activities including IMT studies are growing and
  the number of participants is increasing.
• Recent achievements relevant to IMT
• Information on mobile operators frequencies,
  technologies, and license duration
  (APT/AWF/REP-15)
• APT 700MHz band plan (also included in Rec. ITU-R
  M.1036)
• Survey and forecast of mobile communications
  (also included in Rep. ITU-R M.2243(IMT.UPDATE)
• Following the decision of a new APT Documents
  Framework approved at the 35th Session of the
  APT Management Committee, AWG updated its
  approval procedure of technical documents.
• AWG can send a Liaison Statement to external
  organizations
• This would facilitate AWG to provide necessary
  communication and share updated information with
  external organizations.

Market of Mobile Communications Services

• No. 1 market in the world in terms of the number
  of subscriptions
• Mobile cellular subscriptions 2.9 billon in 2011
• Active mobile broadband subscriptions 420
  million in 2011
• Subscriptions per 100 inhabitants (i.e.,
  penetration rate), however, are still low
  compared to other developed regions
• The situation of access to mobile communication
  services is very different depending on the
  countries in the Asia-Pacific region
• 2G service (GSM/CDMA) is still popular, however,
  mobile broadband demand is increasing

APT Survey Report on this Subject

• A new APT Report was developed regarding
• Survey of trend and forecast on mobile
  communications in APT countries (APT/AWG/REP-28)
• This report contains the information and views
  from some APT administrations as their responses
  to the Questionnaire.
• This Report concludes that
• A continuous growth on the number of mobile
  subscriptions has been observed in the last
  several years.
• A continuous growth on the mobile data traffic
  has been observed in the last several years and
  this trend is expected to continue because of the
  increased penetration of various kinds of mobile
  devices and Internet-based mobile applications,
  evolution of mobile network, and so on.
• It is also expected that further evolution and
  innovation of mobile communications will provide
  more enhanced existing services (e.g., voice,
  streaming, social networking) and inspire various
  kinds of new services (e.g., for improved life
  quality, security and safety, education, etc.).

Studies on future IMT technologies being
considered in AWG
11
TG-IMT in AWG(1)

• Task Group-IMT (TG-IMT) in Working Group
  Technology Aspects (WG-TECH) focuses on the work
  of the following items
• To review activities on the future development of
  IMT-2000 and IMT-Advanced discussed in the ITU-R
  Working Party 5D
• To study service and technology related aspects
  of the future development of IMT-2000 and
  IMT-Advanced as well as the requirements and
  needs of the developing countries.
• Regarding the second item above, some new topics
  were proposed to be studied as future IMT
  technologies, such as
• Active Antenna Systems
• Converged RAN base stations
• Heterogeneous Network

12
TG-IMT in AWG(2)

• Before initiating these new technical studies,
  however, TG-IMT agreed that it is essential to
  collect views from APT members regarding future
  IMT technologies.
• Countries in the region have divergent and
  different situations in terms of IMT system
  deployment
• Identification of IMT technologies issues in the
  region is essential for consideration of a future
  IMT system in AWG
• For this purpose, the Questionnaire on
  Development of future IMT technologies was
  developed in the 12th meeting of AWG.

13
Questionnaire on Development of future IMT
technologies

• The Questionnaire includes the following aspects
• Mobile broadband development
• Service and applications
• Development and operations
• Mobile terminal
• Evolution strategy
• Future plan
• The 13th meeting of AWG (September, 2012)
• Review the responses to this Questionnaire.
• The 14th meeting of AWG (Spring in 2013)
• Target to summarize the regional views on future
  IMT technologies and develop a new APT Report

Workshop on IMT in AWG-13

• Objective
• Exchange information among APT members with an
  overview of and understanding on the situations,
  activities, views, etc. related to IMT and
  facilitate IMT-related work including WRC-15
  Agenda Item 1.1
• Scope of workshop
• Presentations by administrations and industries
  in the region
• Each presentation may include the followings (but
  not limited to them)
• Current market situation of mobile communications
  supported by IMT,
• On-going activities and/or future plans related
  to IMT,
• Views on future-looking activities for IMT
  (e.g.,WRC-15 agenda item 1.1, spectrum
  harmonization in the Asia-Pacific region),
• Expectations and/or suggestions in AWG activities
  related to IMT, etc.
• The workshop does not exceed half a day in
  duration and is preferably held in the first day
  of the 13th meeting of AWG (AWG-13)

Final Remarks

• AWG will continue to contribute studies on IMT to
  ITU-R WP 5D.
• AWG also welcome any expectations or suggestions
  from WP 5D for further closer collaboration in
  any matters of mutual interest.
