  1. July 2003 doc: IEEE 802.11-03/557r0 Discussion on11k MIB extensions Joe Kwak, Marian Rudolf InterDigital Kwak/Rudolf, InterDigital

  2. Outline • Introduction • Overview on existing MIB structure • MIB with future 11k extensions (“Wish-list”) • Proposal on how to structure extended 11k MIB • Summary Kwak/Rudolf, InterDigital

  3. Introduction • Goal of this contribution is to establish a frame work for future MIB extensions by 11k - no focus on detailed statistics or measurements to be included… Kwak/Rudolf, InterDigital

  4. Overview on existing MIB structure (1) Legend: MIB as by 802.11 baseline Added to MIB by a / b / d / g(D8.1) / h(D3.3.4) / e(D4.0) Current proposed 802.11k extensions (D0.2) (Continued…) Kwak/Rudolf, InterDigital

  5. Overview on existing MIB structure (2) Legend: MIB as by 802.11 baseline Added to MIB by a / b / d / g(D8.1) / h(D3.3.4) / e(D4.0) Current proposed 802.11k extensions (D0.2) Kwak/Rudolf, InterDigital

  6. Existing MIB structure: STA Config. Table Legend: MIB as by 802.11 baseline Added to MIB by a / b / d / g(D8.1) / h(D3.3.4) / e(D4.0) Kwak/Rudolf, InterDigital

  7. Existing MIB structure: Operation Table Legend: MIB as by 802.11 baseline Added to MIB by a / b / d / g(D8.1) / h(D3.3.4) / e(D4.0) Current proposed 802.11k extensions (D0.2) Kwak/Rudolf, InterDigital

  8. Existing MIB structure: Counters Table Legend: MIB as by 802.11 baseline Added to MIB by a / b / d / g(D8.1) / h(D3.3.4) / e(D4.0) Kwak/Rudolf, InterDigital

  9. Existing MIB structure: Peer Stats. Table Legend: MIB as by 802.11 baseline Current proposed 802.11k extensions (D0.2) Kwak/Rudolf, InterDigital

  10. MIB and future 11k extensions (“Wish list”) (1) • (1) More information pertaining to particular STA’s • PHY measurements (own AP + neighbors) • MAC measurement reports (own AP) • Capabilities and Configuration • (2) More information pertaining to global status of BSS • Association / Roaming / Authentication / Security status and history (to some extent) of all STA’s • Load / Congestion / Traffic mix • Neighbors / Interference / Interference sources (Continued…) Kwak/Rudolf, InterDigital

  11. MIB and future 11k extensions (“Wish list”) (2) • (3) Extensions to SMT notification (“events”) • Mobility related notifications • Traffic / congestion related notifications • (4) Possibility to initiate STA measurements by an outside Network Management Entity (NME) • “Action table” Kwak/Rudolf, InterDigital

  12. How to organize future 11k extensions best ? • Some thoughts… • Structure of MIB tables and attributes probably more of a concern for human readability than it is for accessibility by an outside NME • Some possible 11k extensions are in principle easy to incorporate into existing MIB structure • SMT notifications • “Passively” observable MAC/PHY measurements • Others will anyway require new MIB tables • Peer measurements and statistics • “Action tables” Kwak/Rudolf, InterDigital

  13. Proposal (1) Legend: MIB as by 802.11 baseline Added to MIB by a / b / d / g(D8.1) / h(D3.3.4) / e(D4.0) Current proposed 802.11k extensions (D0.2) Proposed in this contribution Extensions to AP SMT notifications would go here Peer MAC stats go here, mostly passively observable (but not peerLastReceivedRCPI (Continued…) Kwak/Rudolf, InterDigital

  14. Proposal (2) Legend: MIB as by 802.11 baseline Added to MIB by a / b / d / g(D8.1) / h(D3.3.4) / e(D4.0) Current proposed 802.11k extensions (D0.2) Proposed in this contribution Peer PHY measurements (reported or passively observable) go here Association / Authentication / Roaming status etc of all STA’s in BSS MAC and PHY BSS statistics and measurements: load / congestion / interference / neighbors … Interface for NME to force / prioritize 11k actions … Kwak/Rudolf, InterDigital
