2. 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

3. 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 6 th 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

4. Strategic Direction ARIB will contribute to form the consensus building of IMT-Advanced, take decision on IMT- Advanced, 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

5. 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

6. Next Steps/Actions ARIB will contribute to finalize the Preliminary Draft New Recommendation [IMT.RSPEC] in the 10 th meeting of ITU-R WP5D ARIB will also contribute to develop the Preliminary Draft New Recommendation/ Report [IMT.UPDATE] 6

7. 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” 7

The importance of cooperation on IMT standardization was emphasized in their contributions. Update to the GSC-14 Resolution on IMT Standardization is recommended in order to include the current activities of 3GPP, ITU-R WP 5D and other PSOs. Resolution (to be updated) A drafting group will be set up to discuss with updating the Resolution GSC-14/01 on Continuing Cooperation on IMT Standardization 8
