  1. Global Standards Collaboration (GSC) 14 Toward Harmonized UHF Usage for IMT Services Dr. LEE, HyeonWoo Chair of PG701, TTA

  2. Highlight of Current Activities • WRC-07 identified some of UHF band, so called digital dividends, for the IMT on a regional basis. • Region 1: 790-862 MHz • Region 2: 698-806 MHz • Region 3: 698-806 MHz for 9 countries* and 790-806 MHz for others * Bangladesh, China, Korea (Rep. of), India, Japan, New Zealand, Papua New Guinea, Philippines and Singapore MHz 1710 1885 2025 3600 450 790 862 3400 960 2300 2400 WRC 2000 WARC 92 WARC 92 WRC 2000 WRC 2000 Region 1 2110 2200 470 806 698 WRC 2000 WARC 92 WARC 92 WRC 2000 Region 2 WRC 2000 790 WRC 2000 WARC 92 WARC 92 WRC 2000 WRC 2000 Region 3 698 806 Regional identification Global identification Country basis identification

  3. Highlight of Current Activities • Mobile Industry is now seeking for the way to use the band in more efficient manner. • CEPT is finalizing the harmonized frequency arrangement in the band 790-862 MHz which is FDD arrangement with 30x2 MHz block with optional approach of TDD on the entire band. • US licensed the band 698-806 MHz based on the frequency plan allowing technology neutrality and sharing with other services. • ITU-R revised the Rec. ITU-R M.1036-3 in order to define harmonized frequency arrangement for the bands newly identified at WRC-07. • It is likely that some options for UHF band are getting in with regard to the Regional identification as well as country-specific use.

  4. Proposed Strategic Direction • As ITU-R was invited in the Resolution 224, harmonized frequency arrangement should be encouraged to realize the objective of IMT identification. • The harmonized frequency arrangement is key measure of efficient use of spectrum. • With regard to the current identification of UHF band, Regional approach is likely for the harmonized frequency arrangement.

  5. Challenges • Different usage of the UHF band in Asia-Pacific • Different timing for digital dividends • Different use of current system in the bands • Different identification among countries * Brunei Darussalam, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, Vietnam

  6. Next Steps Toward Harmonized Usage of UHF for IMT services • Next Steps in Asia Pacific Countries • AWF (APT Wireless Forum) is investigating on how to develop the harmonized frequency arrangement suitable for Asia-Pacific Region. • Next Steps in Industry • In addition to the Administrations’ effort in AWF, harmonized efforts within industry is really necessary to achieve the overall objective of IMT identification such as economy of scale from the unified regulatory standards, e.g., RF specification. • Technical analysis for compatibility with existing/between IMT as well as implementation measures are needed. • Next steps in PSOs • Efforts for harmonized usage of UHF spectrum for IMT service
