6. CR submissions6.1. Bin Tian (Qualcomm) presented “CRs on Miscellaneous PHY CIDs,” based on the
submission doc.11-20-0792-00.6.1.1.Summary
6.1.1.1. Resolution for the comments with following CIDs related to the PHY specification of the IEEE 802.11ax D6.0 are proposed.
6.1.2.1. CID 24502: The commenter mentioned that the discussion during the WG letter ballot phase is not valid reason for the rejection since we are in the IEEE-SA ballot phase. We can have the same straw poll as we had during the WG letter ballot phase. The group discussed the cases for HEMUBeamformerOptionImplemented is true and HESUBeamformerOptionImplemented is true. As a result of the discussion, the text in the resolution column will be updated.
6.1.2.2. CID 24561: A participant asked for the reason why some forms of L-STF and L-LTT are still needed even in green field design as described in the resolution column. The answer was that those fields are needed for packet detection and identification of PHY format.
6.1.3.Next Step6.1.3.1. Bin will update the document incorporating the result of discussion.
7. AoB7.1. No other CR submission is available today.7.2. Chairperson asked for the need for puncturing discussion during the next teleconference

7. CR submissions7.1. Jonathan Segev (Intel) presented “SA Ballot Comments Resolutions for FTM
CIDs,” based on the submission doc.11-20-0857-00.7.1.1.Summary
7.1.1.1. Resolutions for the comments on FTM related spec defined in the IEEE 802.11ax D6.0 with following CIDs are proposed.
7.1.1.1.1. CIDs: • 24487, 24489.7.1.2.Discussion
7.1.2.1. CID 24487: A member commented that the first sentence in the resolution column saying that “this is a duplicate of LB 244 CID 22322 receiving same resolution” may not be appropriate since this is the initial SA ballot. Also the member mentioned that the comment should be accepted. This CID needs more time to be resolved.
