CJK9, Zhangjiajie, China 2/10 Introduction Main Activities Proposal for Cooperation

CJK9, Zhangjiajie, China 3/10   Sep Approval of CR PG (PG314) in TC3   Dec Kick-off meeting in TTA   Jan Renamed to PG705 in TC7 (by restructuring of TTA Standardization Committee)   30 members from government, universities, manufacturers, carriers, broadcasters and research institutes - Chairman: Ms. Hyangsuk Seong (Radio Research Agency)  History and organization 1. Introduction   Review on the R&D of CR technology   Standardization of cognitive radio technology in a service   Standardization of technology using FACS ※ FACS: (Flexible Access Common Spectrum)  Terms of Reference

4/10 CJK9, Zhangjiajie, China 2. Main Activities 2007 … Kick-Off Meeting: Election of Chairmanship, Establishment of ToR, … Developed a technical report on guidelines for FACS usage in line with the development of domestic technical regulation FACS 1) Usage Study on CR-based license-exempt communications CR in license-exempt comm. PG 314 PG 705 ‘07. 4 ‘ ‘ ‘08. 4 ‘ Study on CRS in the land mobile service CRS in the LMS ‘09. 4 ‘ … 1) FACS : Flexible Access Common Spectrum (57~64GHz)

5/10 CJK9, Zhangjiajie, China 2-1. Technical Report on FACS Usage in 2008   FACS (Flexible Access Common Spectrum)   57~64 GHz, Open to anyone meeting interference criteria below   introduction of technology neutrality and less regulation to promote further growth in the domestic radiocommunication market Interference criteria of a device using FACS = Power x BW ratio x (DF ratio or T ratio ) x BF Power: Transmit Power DF ratio : Duty Factor standard / Duty Factor T ratio : Channel Occupied Time standard /Occupied Time BF: Balancing Factor ex) LBT: 1, FH: 0.95, DS: 0.8 Freq. (BW) Time (Duty Factor) Space (Power) Constant

6/10 CJK9, Zhangjiajie, China 2-2. Review of Activities on CR in Korea   CR/SDR Forum in Korea (found in Nov. 2008)   Analysis of technology trends, technology development and cooperation for standardization, development of service models for application of technologies and radio wave policies, and development of related policies and promotion of technologies   International workshop 2009 on CR and SDR: April 2009 in Seoul   CR PG is currently studying the two work items   CR-based license-exempt radio communications   CR System in the land mobile service

7/10 CJK9, Zhangjiajie, China 2-3. Review of ITU Activities on CR   ITU-R WP1B   responsible group on WRC-11 agenda item 1.19 “To consider regulatory measures and their relevance, in order to enable the introduction of SDR and CR system, based on the results of ITU-R studies”   ITU-R WP5A   Report on CR technology is under preparation in land mobile service   ITU-R WP5D   initiated study on CR technology in IMT in Feb meeting Note: A SDR Report ITU-R M.2117 on land mobile service and amateur service developed by ITU-R WP8A (former WP5A) and WP8F(former WP5D)

8/10 CJK9, Zhangjiajie, China 2-4. Review of other Activities on CR   EU   E2R   E3 : plan to hold workshop in October 2009 in Korea   IEEE   : develop a standard for a cognitive radio-based PHY/MAC air interface for use by license-exempt devices on a non-interfering basis in spectrum that is allocated to the TV Broadcasting Service   P1900: develop supporting standards dealing with new technologies and techniques being developed for next generation radio and advanced spectrum management

9/10 CJK9, Zhangjiajie, China   Exchange of information on R&D and standardization on CR technology is desirable. In particular, what kind of services are considered to use CR technology in what frequency band in your country?   Since CR is considered to be useful technology to provide flexibility and versatility of resources and radio systems 3.
