Hi Payam, Thank you for preparing the resolution of the CID2215. As far as I understand, the proposed resolution is to remove the exception authorizing the EHT STA to ignore the quiet elements that are dedicated to the protection of the rTWT. But the last sentence of the document you propose (683r0) mentions the contrary :
“Non-AP EHT STAs may behave as if such overlapping quiet intervals do not exist.”
So I don’t see how the proposed text solves the fairness issue raised by the CID between legacy and EHT stations. More generally, I think the spirit of your resolution goes against the idea that the support of the low latency feature is optional for the EHT STA. At least the EHT STA will have to decode and store the information of all the quiet elements that will be put in place to protect recurrent rTWT periods. Despite legacy stations, EHT station cannot ignore that a lot of quiet elements can be present and shall then be able to support it. I think that to solve the problem of fairness raised by the CID2215, we should rather think to an optional mechanism put in place or not by the AP (depending on the type of stations
associated to it) to reserve the medium in a way that will be fair for both legacy and EHT STAs. I think the best solution would be to rely on NAV protection that can easily be put in place by an AP reserving the medium prior the start of the rTWT period. Let me know you opinion. Best regards.

Hi Alfred,
Could you please add 11-21/0683 to the comment resolution agenda. This submission attempts to resolve a TBD. Targeted CID per title.
Hello all,
This is a contribution to expand TBD rules for scheduling quiet intervals to protect restricted TWT SPs, and also announcing them. Your comments much appreciated.
