• CID 1 -15 on security basically accepted
• 11.2.1.13 editing changes were discussed on the Awake Window backoff counter description. Initial changes captured in 343r0 but discussion resulted in action for editor to make more changes.
• CID 49 TDLS prohibited bit. Bit is now in Extended Capabilities element, not mention filtering. Noted that Hotspots will filter traffic directly between STAs. Discussion on fact that now an AP has specific TDLS feature.
• CID 40. Discussed again TDLS PSM Awake window. “The Awake Window Counter counts down backoff slots that are determined using the AIFS parameter from the EDCA AC_BE parameter set, in the same manner that normal backoff slots are determined according to 9.9.1.5. The initial value of the Awake Window Counter shall be set to the value in the Awake Window Slots field of the TDLS Peer PSM request frame that caused the wakeup schedule. The Awake Window Counter begins counting at the beginning of the Awake Window and stops when it reaches zero.” Also proposed to change “Awake Window Backoff field” into “Awake Window Slots Field”.
• CID 39. Fixed Awake Window sentence should be removed as it is hard to determine this condition. Agreed.
• CID 38. Using the Awake Window backoff, suggested to remove “…, while avoiding long wakeup windows when the medium is lightly loaded.” Much discussion on this resulted in changes to CID 40 wording above.
