May 2009                                    doc.: IEEE 802.11-09/0509r2


                      OBSS Directions

        1. How the information is used to share the
           medium?
        2. Set of information that needs to be exchanged
        3. Impact of the OBSS solution on ‘legacy’ BSSs
           • Implementing the OBSS solution needs to
               provide a compelling benefit (in the presence
               of legacy BSSs) – otherwise no one will
               implement it
           • See 7.5 in 08/944r7

                                      802.1AVB Topics
 1. What is the worst case delay when streaming under different conditions? (good
    conditions – 1msec, moderate – 8 msec and heavy congestion 800 msec)
       –     subset of options used
       –     channel conditions
 2. Is there a mechanism specified in 802.11 to propagate the worst case delay under
    current conditions, to upper layers?
       1.    What data makes the most sense? 2. are there mechanisms to pass this data? 3. if not, can we define them?
 3. 802.11 TSPEC mapping to 802.1Qav TSPEC – plan for a presentation
 4. How are QoS errors fed back from the 802.11 MAC? Need to determine if 11k
    traffic stream/category statistics are sufficient.
 5. Expectations (from .1AVB perspective) for the Joint meeting :
       –     Answers to #1 above
       –     Updates on #2 and #3
 6.    SRP over 802.11 – need for relaying stream information (09/403r0) – list choices,
       pros/cons of each for discussion jointly
 7.    Update each other on status of drafts

                              Timeline Review
 1. D1.0 WG letter ballot – according to timeline, scheduled for Nov
    2009
 2. PAR topics:
       – Graceful degradation of audio video streams when there is insufficient channel
         capacity, by enabling packet discarding without any requirement for deep packet
         inspection,
       – Increased robustness in overlapping BSS environments, without the requirement
         for a centralised management entity,
       – Intra-Access Category prioritization of transport streams by modifying EDCA
         timing and parameter selection without any requirement for deep packet inspection,
       – Improved link reliability and low jitter characteristics for multicast/broadcast audio
         video streams
       – Interworking with relevant 802.1AVB mechanisms (802.1Qat, 802.1Qav, 802.1AS)
 3.    D1.0 is required to be complete – address the PAR scope entirely
 4.    Potential for a 4 month slip
