2. Editor’s report.
Emilyis working on incorporating the editorial comments, and is targeting to have Draft 3.01 with all of the editorial comment resolutions incorporated, in time for the ad-hoc meeting next week.
3. Comment resolutions
Alex reviewed the Multicast Diagnostics comments, see
•CID 17- agree with proposed resolution

Ganesh reviewed the Timing Synchronization proposed text changes, continuing from the Denver meeting discussion. Believe that this text will address all of the timing measurement related comments. See and .
Discussion:
-There is an alternate solution that has been proposed for timing measurement, using beacon frames. Ganesh is preparing a presentation describing the alternative, and the issues with it, including the need for hardware support for statistical processing, and lack of symmetry between non-AP STAs and APs.
-The solution in 08-891 uses management action frames rather than public action frames, since the frames are exchanged only between APs and associated stations.
-MIB variable definitions need changes to index by MAC address, also need text to describe use of MIB variables.
-Are using Time of departure solution for both location and timing measurement. Need text to clarify that the accuracy required for the 2 applications is different.
-No additional annex changes are needed.
-Next steps, get additional review from commenters, and prepare the corresponding comment resolutions.
Ganesh reviewed the proposed resolutions for the STA Statistics category comments, see:
and
•CID 12, 14, 49, 110, 155, 157, 199 - agree with proposed resolution
•CID 375 – Change to counter, add a sentence to deal with the case of when the STA trigger limit is greater than that requested by the AP.
•CDI 635 – Change to accept
•CID 715 – agree with proposed resolution
•CID 1222 – Same as CID 199
•CID 1242 – Agree, delete duplicate resolution
•CID 1283 - agree with proposed resolution
•CID 1243 - agree with proposed resolution, slight wording edits
•CID 1297 - agree with proposed resolution, slight wording change
•CID 1300 - agree with proposed resolution
•CID 1415 – Defer, investigate needed .11n triggers; Have considered adding A-MPDU and A-MPDU measurements previously, not added, since already have MSDU and MPDU triggers.
Ganesh reviewed the proposed resolutions for the TCLAS category comments, see:
and
•CID 337–Counter, add a new classifier type for fixed IPv6
•CID 338 – Counter, insert Classifier Mask in Type 3, add text saying that the field is reserved.
•CID 339, 637, 1305, 1306 - agree with proposed resolution
•CID 1307 – Agree with proposed resolution to keep the example; example was added in response to previous comments. Ganesh to confirm that commenter can live with this. Defer for agreement confirmation.
•CID 1308 – Agree on “counter”, Ganesh to agree on specific text with the commenter. Defer for agreement confirmation.
•CID 1309 – Propose Accept, add anew classifier type 4, don’t restrict to specific protocols.
Agreed to start the Tuesday at 8:00am Pacific, as we will need to finish at 2:30pm on Wednesday.

1. Chair called meeting to order: 8:10am Pacific
2. Comment resolutions
Dorothy reviewed the General category comments, see .
•CID 99, 1310- agree with proposed resolution

•CID 183 – already done in FBMS
•CID 224, 225, 226 – agree with proposed resolution
•CID 235 – accepted, “Request Information” is one item added
•Comment category 251 – Defer, management frame priority
•CID 326, 329 - agree with proposed resolution
•CID 331 – Counter. Channel usage element is deleted, traffic generation retained, as channel usage is not in the Beacon frame.
•Comment category 365 – Change to counter, and insert one sentence in 11.20.1 to cover all cases.
•CID 269 – Defer – Directed multicast presentation planned again in September
•CID 400, Comment category 1274 – AP Collaboration. Proposed decline, with reason updated from prior comments. Would like to find a way forward. Concern with the complexity of the required infrastructure.
•Comment category 401 – Discussion – Interpretation of PAR can be argued either way. Propose decline, add more detail on each of the features. Plan one motion for the category, of course motions will be considered as they are brought forward.
•CID 1239 – Defer, Qi to propose text, plan to discuss on Aug 26th con call
•CID 1257 – Defer, Qi to propose text, plan to discuss on Aug 26th con call
•Comment category CID 1347 – Agree, slight wording changes.
Dorothy reviewed the remaining Diagnostics category comments, see and .
Most of the comments were reviewed in Denver. Remaining comments:
•CIDs 163, 227 – Deferred, Allan, Peter are the commenters and will propose a solution. Concern that the details requested are similar to ones rejected previously.
•CIDs 309, 1229 – Counter, adopt text proposed by the commenter.
•CIDs 1246, 1248 – Deferred. Further discussion needed to try to find a way forward. Discussion: See true value of a feature when all devices implement diagnostics. Want to be able to diagnose issues. Diagnostics used only for problems, or once upon association. Entire WNM is optional. Concern about diagnostics not being needed in consumer class devices. How does this benefit home networks? WFA will have a different view. Our job here is to give a recommendation. Implementations can choose to implement specifics or not.
There is one Annex category comment, CID 241. Proposed resolution: Counter, change Change from
(CF8 & CF11 & CF13 & CF15):O to (CF8 & CF11 & CF13 & DSE5 & DSE6 & DSE7 & DSE8 &
DSE9):O.

•CID 93 – Decline, focus is on infrastructure.
•CID 94 – agree with proposed resolution

•CID 114 – See text in 11.2.1, move sleep mode text to the power management section, to follow TIM broadcast.
•CID 133 – Decline, Null data frame can be sent even when RSN is enabled, additional explanation of the capability.
