That response transmission should be restricted, such that it too, must ensure that it will not interfere with an ongoing exchange, using whatever SR technique is avilable at the response transmitter STA, with a preference for SRP if enabled and a fallback to OBSS_PD if SRP is not enabled. Since a normal response is allowed to ignore all CCA indications, the responder needs to be able to tell the difference between a normal eliciting PPDU/MPDU and one an eliciting PPDU that Provide an indication within MPDUs of whether the MPDU was transmitted during an SR opportunity or not, and add a restriction on the response transmission to that SR PPDU transmission such that the response must examine the medium condition before responding and obey transmit power restrictions that might be in force due to ongoing SR conditions, e.g. OBSS_PD based transmit power restriction. Expect a submission that details such changes. Revise – generally agree with comment, TGax editor shall incorporate changes in
