11 Research activities on technologies for future mobile communications in Asia-Pacific region Chair TG-IMT, APT Wireless Group
2 Introduction In the 12 th meeting of APT Wireless Group (AWG), 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 the Asia-Pacific region –AWG workshop on IMT
33 Overview of APT Wireless Group
4 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

6 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 35 th 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.
77 Overview of mobile communications in the Asia-Pacific region
8 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 Market of Mobile Communications Services Source: ITU World Telecommunication /ICT Indicators database
9 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)(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.).
10 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 12 th 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 13 th meeting of AWG (September, 2012) Review the responses to this Questionnaire. –The 14 th meeting of AWG (Spring in 2013) Target to summarize the regional views on future IMT technologies and develop a new APT Report
