27.5.6 The short feedbacks mechanism is suitable for collecting information from the STAs like BSS color information the STAs detect in PPDUs from OBSS. This comment was submitted during D1.0 comment collection but not resolved doe to lack of time. Define specification of short feedback to collect BSS color information the STAs detect in OBSS PPDUs. By allocating keys (indexes) on each RU and the AP announces the allocations to STAs, the collecting mechanism can be realized. 27.5.6 NDP feedback report triggers are meant to be sent regularly with predefined intervals and at predetermined transmission times. This way, the STA can know when to be in the awake state when it wants to make a resource request. The specification needs to describe a way for the AP to indicate to the STAs at what target transmission times these NDP feedback reports trigger frames will be transmitted and with which periodicity. Add a mechanism for the AP to indicate to the STAs the target transmission times and periodicity of the NDP feedback reports trigger frames. This should account for the possible different types of feedbacks. We can include such information in the NDP Feedback Report Parameter Set element, or in a broadcast TWT element. There is a lot of repetition between the 1st and 2nd paragraph in this section. Suggest consolidating the two paragraphs and removing redundent sentences add the reference with "28.3.17 HE TB NDP feedback PPDU" at the end of the sentence. For example, "... is an HE TB PPDU without data payloads as defined in 28.3.17 (HE TB NDP feedback PPDU)" as in comment NDP feedback reports can currently be sent only by associated STA. In order to reduce the use of EDCA for transmissions of unassociated STAs to the AP or to simply reduce the latency to access the medium for unassociated STAs, NDP feedback report procedure should be extended to allow unassociated STAs to send a resource request with the NDP feedback report. Modify the NDP feedback report poll trigger frame and the NDP feedback procedure to allow unassociated STAs to send an NDP feedback report. The procedure should also allow the STA to be triggered by the AP, following an NDP feedback report poll resource request. 4
