  3. Mobile Communication Technical Committee (TC7) IMT-Advanced PG (PG701) IMT WiBro PG (PG702) Mobile Platform & Service PG (PG703) WLAN PG (PG704) Cognitive Radio PG (PG705) VHO PG (PG706) IMT Evaluation PG (PG707) 1. IMT WiBro PG : Overview of TC (TC7) • ToR (Terms of Reference) of TC7 • To perform the standardization on mobile communication systems • in cooperation and coordination withother related institutions • in Korea and overseas • To contribute to their international standardization activities

  4. IMT WiBro PG(702) Service & Network WG Radio Access WG IOT / CT WG International Cooperation WG ◦ Radio Access Standardization on IMT WiBro ◦ International Standardization on IEEE 802.16, ITU-R WP5D ◦ Service and Network Requirements for IMT WiBro ◦Standardization on authenti -cation for WiBro service ◦Standardization on WiBro to other network interworking ◦ Profiling, Interoperability Test and Conformance Test Standardization on IMT WiBro ◦ Activities and follow-up related to WiMAX forum ◦ International cooperation for WiBro standardization ◦Analysis on standardization trends for IMT WiBro 1. IMT WiBro PG under TC7: ToRs • ToR (Terms of Reference) of IMT WiBro PG • Domestic Standardization related to IMT WiBro • Activities for Global Standardization related to IMT based on WiBro • Cooperation with International Standardization Organization related to • IMT based on WiBro

  5. 2. WiBro Femto cell Standardization: Needs • Needs for WiBro service at Home Area • To provideindoors service coverage by solving dead zone problem • To satisfy the requirement of data traffic originated from indoors • - Existing RAS cannot handle all traffic demands from indoor • To provide service continuity between WiBro and indoor RAS without changing UE • Needs for WiBro service at Business Area • To provide in-building service coverage by solving dead zone problem • To satisfy the requirement of data traffic originated from in-building • - Existing RAS cannot handle all traffic demands from in-building • To satisfy security requirements • To provide customized WiBro services • To provide service continuity between outdoor WiBro and business WiBro • without changing UE

  7. 2. WiBro Femto cell: Technical Highlights • Technical Highlights for WiBro Femtocell • Handover • Macro to Femto, Femto to Femto ; scanning of neighbor WFAPs (whitelist) • Femto to Macro ; existing handover procedure between WiBro WFAPs • IDLE mode • Outdoor RASto WFAP in idle mode • WFAP to outdoor RAS in idle mode • Auto Configuration • Plug & Play, auto configuration • Self registration and authentication • Self Optimization • RF planning to mitigate the effects of interference • Transmission power control • Self fault detection • UE functionality • Registration of WFAP to accessible WFAP list (whitelist) • Scanning of accessible WFAP / Assign priorities

  8. 2. WiBro Femto cell Standardization: Plan • Standardization Plan for WiBro Femtocell (TC7 IMT WiBro PG) Apr. 08 Mar. 09 Jun. 09 Dec. 09 2010 WiBro Femtocell Standard Adoption of Work Item Approval of Standard Drafting (Service requirements and technologies for WiBro Femtocell) WiBro Femtocell Technical Report Approval of Standard Preparation of Work Item Adoption of Work Item / Drafting (Technical highlights of International / domestic standards for WiBro Femtocell)

  9. 3. ITU-R WP5D Issues on Femto cell • ITU-R WP 5D has begun discussion on femto cells (or their equivalent) for IMT. • ITU-R WP 5D wishes to collect information on femto cells to determine if WP 5D can add value to the understanding of femto cell (or equivalent) deployment for its members (Administrations, Sector Members, Associates, etc.). • Specifically, WP 5D is aware that EOs may be working in this area. • ITU-R WP5D has requested that EOs provide general information the following subjects after WP5D 4th Meeting(Geneva) • What is your organization’s definition of a femtocell (or equivalent)? • Standards and specifications • Describe the network architectures being considered • What applications for femtocells (or equivalent) are being considered? • What deployment issues are being discussed – for example:

  10. 4. Future Activities on ITU-R WP5D femto cell discussion. • TTA received “LIAISON STATEMENT TO EXTERNAL ORGANIZATIONSREQUEST FOR INFORMATION ON FEMTOCELLS(Document 5D/TEMP/152-E) from ITU-R WP5D • TTA Mobile Communication Technical Committee(TC7) is going to consider this liaison statement. • If necessary, we will prepare a response liaison for the next WP5D Meeting(June, 2009)
