March 2021 doc.: IEEE 802.11-21/0413r0 CC32 Comment Resolution Standard 802.11 processes were used to resolve the comments received in response to the WG CC32: 1. A comment resolution report was created: 11-20/1262 2. All resolutions were discussed and approved by motion (note: all motions in the AANI SC require a 75% majority to pass, anyone present may vote) 3.

March 2021 doc.: IEEE 802.11-21/0413r0 Discussion at the January WG Closing Plenary During the discussion on the motion to approve 11-20/0013r10 the following points were raised (summarized from the minutes 11/21/0046r0): In support of the motion: 1. the group have worked very hard to finalize it 2. AANI has been open to everyone and followed the process made by AANI Chair 3. If there are serious objections, why have those members not been attending the AANI? Should they have voted No at an earlier stage? Against the motion: 1. I have some technical concerns . there is a lack of clarity regarding the 5G WLAN interworking. There was no conclusion about how to resolve these technical issues. Therefore, it s not regarded as a good report and in addition, there are only a few people who participate in AANI. 2. I think the previous comment should be listened to 3. I did contribute an alternative report and stating that this new report could be merged with the original. However, the AANI group rejected this possibility. Submission Slide 5 Joseph Levy (InterDigital)
March 2021 doc.: IEEE 802.11-21/0413r0 Chair s Perspective The statement made against the Motion to Approve during the January called attention to comments made during the Comment Collection. These Comments were resolved via the standard 802.11 comment resolution process over many months (September January). The comments sighted were discussed at multiple AANI SC meetings Numerous calls for contributions to resolve these comments were made No text proposals to 11-20/0013 were provided. A motion to replace 11-20/0013 with 11-20/1376r0 as the baseline failed (Y:10 N:12 A:9 DNV:12) The proposed resolutions were stated at several AANI meetings, prior to the motion being run. The resolutions of these comments were agreed by motion (Y:11 N:1 A:11 DNV:10), in January The AANI SC worked to resolve all comments and concerns, was open to all contributions, openly shared status, and openly shared all proposed comment resolutions.

March 2021 doc.: IEEE 802.11-21/0413r0 Motion from the January AANI meeting Motion 6: Move to accept the following resolution for CIDs: 68, 69, 70, 71, 80: REJECTED Significant discussions were held during several AANI SC teleconferences and several related contributions were discussed: 11-20/1472r0, 11-20/1376r0 and 11-20/1031r0. However, no specific text changes to 11-20/0013r5 were proposed. Also note, a motion made to approve 11-20/1376r0 as the baseline for the technical report failed and the AANI SC agreed to proceed with comment resolution using 11-20/0013 as the baseline (see minutes: 11-20/1512r1). The comment fails to identify changes in sufficient detail so that the specific wording of the changes that will satisfy the commenter can be determined.
