Purpose

This guide supports the TGh group discussions by providing information on power constraint, power capability, TPC report, tolerances, TPC procedures, and new definitions. It also covers topics related to action frame definition, reason code, status code, new channels, PICS, and MIB. DFS topics include channel switch announcement, use of containers, IBSS, BSS, and DFS procedures. Additionally, this document addresses start-up phase, normal operation, and common framework issues for DFS.

Presentation Transcript

  1. Purpose • Top-down approach for TGh from D1.1 to D2.0 • Guides the group through the discussions • Supporting information for the agenda Mika Kasslin, TGh chair

  2. TPC Topics TPC.1) Power Constraint element (7.3.2.16) • New format proposed in 01/664r0 TPC.2) Power Capability element (7.3.2.17) • New format proposed in 01/664r0 TPC.3) TPC Report element (7.3.2.19) • Transmit Power field syntax TPC.4) Tolerances • Transmit power • Measurements, link margin TPC.5) TPC procedures (9.11) TPC.6) New definitions • transmit power • receiver power Mika Kasslin, TGh chair

  3. General Topics GEN.1) Action Frame definition • New format proposed in 01/665r0 • Defined in 7.2.3.12 and used in 7.4 of 01/664r0 GEN.2) Reason Code • Changes proposed in 7.3.1.7 of 01/664r0 GEN.3) Status Code • Changes proposed in 7.3.1.9 of 01/664r0 GEN.4) New channels (5470-5725 MHz) listed GEN.5) PICS • skeleton in 01/664r0 GEN.6) MIB • proposal in 01/533r0 and 01/664r0 Mika Kasslin, TGh chair

  4. DFS Topics DFS.1) Channel Switch Announcement element • Re-edit in 01/664r0 DFS.2) Use of containers • Discussed in Austin • Defined and used in 01/664r0 (frame -> element -> container) DFS.3) IBSS • Proposal in 01/532r0 DFS.4) BSS • Mechanism and reports in D1.1 DFS.5) DFS procedures • Text proposal in 01/664r0 Mika Kasslin, TGh chair

  5. DFS Framework Issues Start-up phase: • start-up test period (no less than 30 seconds) • How about upper limit? • start-up phase rate Normal operation: • periodicity of quiet periods to listen radar signals • Tailored for HL/2 with 2 ms frames • Amount of quiet periods (20%) • channel switch time (6 ms) Common: • response time (100 ns) Ideas: • more heuristic methods taking into account radar characteristics • frequency range • periodicity Mika Kasslin, TGh chair
