Update of ARIB Activities on IMT Standardization Document No: GSC17-PLEN-29r1 Source: ARIB Contact: Yoshihide ISHIDA GSC Session: PLEN Agenda Item: 6.1 Update of ARIB Activities on IMT Standardization Yoshihide ISHIDA Director, Land Mobile Communications Group, ARIB

Highlight of Current Activities (1) 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 international standardization activities ADWICS consists of the following five subcommittees Mobile Partnership Subcommittee (3GPPs, oneM2M) Standardization Subcommittee (ITU-R WP5D) BWA Subcommittee (WiMAX, XGP, etc.) MMAC Subcommittee (802.11, UWB, etc.) Mobile Commerce Subcommittee

Highlight of Current Activities (2) Standardization Subcommittee conducts technical studies on IMT and future IMT issues and promotes its standardization through contributions to ITU-R and other activities. ARIB provided updated specifications of IMT-2000 and IMT-Advanced to ITU as one of the global core specification (GCS) proponents ARIB updated ARIB Standards STD-T63/TR-12(CDMA DS), STD-T64/TR-13(CDMA MC) and STD-T94(OFDMA TDD WMAN) according to the progresses of technical fora. ARIB updated ARIB Standards STD-T104 (LTE-Advanced) and STD-T105 (WirelessMAN-Advanced) according the progresses of technical fora.

Strategic Direction ARIB will contribute to achieve the goal of WRC-15 Agenda Item 1.1, i.e. “additional spectrum allocations to the mobile service on a primary basis and identification of additional frequency bands for IMT”. ARIB will continue to contribute to enhance ITU IMT-2000 and IMT-Advanced Standards as one of GCS proponents ARIB will continue to update ARIB’s IMT-2000(STD-T63/TR-12, STD-T64/TR-13 and STD-T94) and IMT-Advanced Standards (STD-T104) based on the study results of the respective technical fora.

Challenges For achieving the goal of WRC-15 Agenda Item 1.1, ARIB will exchange information and views and will coordinate with other PSOs and related groups through ITU-R WP5D/JTG, 3GPPs and other regional activities such as AWG, APG and CJK Standards meeting

Next Steps / Actions ARIB will contribute to achieve the goal of WRC-15 Agenda Item 1.1, “additional spectrum allocations to the mobile service on a primary basis and identification of additional frequency bands for IMT”. To achieve the above goal, ARIB will contribute to - Study on spectrum requirements for IMT - Study on suitable frequency ranges for IMT To achieve the above goal, ARIB will exchange information and views and will coordinate with other PSOs and related groups through ITU-R WP5D/JTG, 3GPPs and other regional activities.

Proposed Modification of Resolution GSC-16/1 Considering that WRC-15 will discuss spectrum matters on IMT under Agenda Items 1.1 and 1.2, Resolution GSC-16/1 (Continuing Cooperation on IMT Standardization) should be updated and modified as follows: To update “ both Recognizing and Resolve part” as appropriate To add issues on WRC-15 Agenda Items on IMT spectrum matters in “Resolves part”

Overview of Advance Wireless Communications Study Committee (ADWICS) Responsibilities To perform the technical studies on advanced wireless communication systems in cooperation and coordination with other related international/national organization To contribute to international standardization activities Structure of the Study Committee (as of May 2013) IMT Partnership Subcommittee was changed to Mobile Partnership Subcommittee because of additional covering of oneM2M MMAC Subcommittee was added because of the merger of MMAC Forum

Scope of Subcommittee Mobile Partnership Subcommittee Operate 3GPPs and oneM2M as one of Organizational Partners Prepare contribution to 3GPPs on national regulatory requirements aspects and downstream the specification developed by 3GPPs for ARIB Standards Standardization Subcommittee Conduct technical studies on IMT and future IMT issues Promote its standardization through contributions to ITU-R and other activities BWA Subcommittee Produce national standards for WiMAX, XGP/AXGP and IEEE802.20 referring to relevant international standards MMAC Subcommittee Produce national standards for IEEE802.11 reffering to international standards and study UWB Mobile Commerce Subcommittee Conduct technical studies on Mobile Commerce

Resolution GSC-16/01 on IMT Standardization (1) Continuing Cooperation on IMT Standardization Recognizing: 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; 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; that ITU-R Study Group 5 and ITU-T Study Group 13 are continuing studies on IMT (encompassing both IMT-2000 and IMT-Advanced); that ITU-R Study Group 5 has completed the evaluation of candidate technologies for IMT-Advanced; that core network(s) are increasingly becoming access technology agnostic; 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; that WRC-07 identified some additional spectrum for the implementation of IMT systems;

Resolution GSC-16/01 on IMT Standardization (2) Continuing Cooperation on IMT Standardization Recognizing:; that WRC-12 may approve a new agenda item for WRC-15 to conduct studies for additional spectrum to be made available beyond 2016; that the UN Broadband Commission has identified broadband as a key infrastructure for developing economies; that work on evolution of the radio technologies may converge to use similar techniques; and that there are related international, regional and national research activities in this area.

Resolution GSC-16/01 on IMT Standardization (3) Continuing Cooperation on IMT Standardization Resolves: 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 use of IMT technologies for broadband services; 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 any additional candidate radio interface technologies for IMT-Advanced among PSOs allowing for efficient, effective and timely development of the IMT-Advanced standard and to continue this exchange for the detailed specifications for IMT-Advanced; to exchange information and views with goal of encouraging the adoption at WRC-12 of a new WRC-15 agenda item on IMT spectrum issues; to exchange information and views on the analysis and assessment of global broadband wireless services and consumer demand for IMT in line with the ITU-R ongoing work on this topic; to encourage the Task Force under the GRSC to actively help in the exchange of information and views mentioned in 5) to 7), with the goal of consensus building; and to review this Resolution at future GSC meetings as required.
