16. Nov 2011
Motion 10
Move to change the resolution for CID 7035 from Revise to Reject as follows:
REJECTED (EDITOR: :37:52Z) -  Basically the TXOP used in EDCA is unscheduled.  The TXOP starts when the first packet is successfully transmitted.  A time division scheme for EDCA TSPECS, along the lines of the HCCA TXOP Advertisement, might work but it would be against the fundamental EDCA scheme which is one of unscheduled and fair sharing. If we scheduled EDCA TXOPs we would effectively be duplicating HCCA and hence if we can support scheduled EDCA TXOPs, we should be supporting HCCA.
The CRC discussed adding support for GCR-SP and would consider a submission from the commenter.
Moved: Alex Ashley
Seconded: David Hunter
Result 5/0/0

17. Nov 2011
Motion 11
Move that resolution to CID 7036 be revised as follows:
"REVISED (GCR: :57-5) The draft should have said "non-GCR-SP".
Change service period definition by changing "non-Groupcast with Retries (non-GCR) SP" to "non-Groupcast with Retries SP (non-GCR-SP)"
Add two definitions to 3.2:
"non-groupcast with retries (non-GCR): A method for delivering group addressed frames without using the GCR unsolicited retry retransmission policy, the GCR block acknowledgement retransmission policy, or the GCR service period (GCR-SP) delivery method."
"non-groupcast with retries service period (non-GCR-SP): A method for the delivery of group addressed frames without the use of a GCR service period.""

18. Nov 2011
Motion 12
Move that resolution to CID 7023 be revised as follows:
REVISED (EDITOR: :07:09Z) - Change "The Drop Eligibility subfield is set to 1 to indicate that MSDUs for this TS may be dropped if there are insufficient resources to transmit this TS in its entirety. The Drop Eligibility subfield is set to 0 to indicate that this TS does not support drop eligibility."
 to
 "The Drop Eligibility subfield is 1 bit in length and is used to indicate the suitability of this TS to be discarded if there are insufficient resources. If there are insufficient resources, a STA should discard the MSDUs or A-MSDUs of a TS with a Drop Eligibility subfield equal to one, in preference to MSDUs or A-MSDUs of a TS whose Drop Eligibility subfield is equal to zero. See The mechanisms for determining whether the resources are insufficient or when to discard MSDUs or A-MSDUs are beyond the scope of this standard.“

19. Motion 13 Nov 2011 Graham Smith, DSP Group
Move that resolution to CID 7074 be as follows:
REVISED (OBSS: :08:45Z) - There is already normative text in this clause to delay the sending of Qload reports, which is supposed to stop qload report bombardment. The values in a Qload report change upon the addition/termination/modification of a TS, or upon the reception of a changed Qload report from an AP in an overlapping BSS. There is a hysterisis of 100 beacon intervals before the data from an overlapping AP is discarded.
Change "Whenever there is a change in the contents of the Qload element, an unsolicited Qload Report Action frame should be transmitted with the RA field set to the broadcast address." to
"Whenever there is a change in the contents of the QLoad element and there is no pending delay period for an unsolicited QLoad Report Action frame, an unsolicited Qload Report Action frame should be transmitted with the RA field set to the broadcast address, after a randomly selected delay between 1 and dot11QLoadReportDelay seconds"
Change "The AP shall delay the transmission of an unsolicited Qload Report Action frame for a randomly selected period between 1 and dot11QLoadReportDelay seconds" to "After this delay, the AP shall transmit an unsolicited Qload Report Action frame that contains the most recently available Qload information."
In annex C on P117L15 add a default value of "10" to the dot11QLoadReportDelay MIB attribute.
In (P51L32) change
"The Overlap field indicates the number of other Aps that are sharing the same channel and whose beacons have been detected or obtained by the AP issuing this beacon. A value of 0 indicates that this AP has not received one or more beacons on the same channel from any other AP within the last 100 beacon periods of this AP."
"The Overlap field indicates the number of other Aps that are sharing the same channel and whose beacons have been detected or obtained within the last 100 beacon periods by the AP issuing this beacon."
On P51L15 change
"The Allocated Traffic Shared field represents the sum of the Allocated Traffic Self values that have been received or obtained from other Aps, plus the Allocated Traffic Self value of the AP itself. Computation of the values represented in the Allocated Traffic Shared field is described in "
"The Allocated Traffic Shared field represents the sum of the Allocated Traffic Self values that have been received or obtained from other Aps whose beacons have been detected or obtained within the last 100 beacon periods, plus the Allocated Traffic Self value of the AP itself. Computation of the values represented in the Allocated Traffic Shared field is described in "
