GSC17-PLEN-29r1 Standards for Shared ICT GSC-17, Jeju / Korea 6 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.

7. GSC17-PLEN-29r1 Standards for Shared ICT GSC-17, Jeju / Korea 7 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”
