CID 2915 is similar to CID 3500 (11/1060r0) which has already passed the motion. CID 3500 is as follows: paragraph and the next two or three seem overly complex with a lot of repetition. For example, The “This second sentence talks about TXOP bandwidth coming from the CTS response to non-HT RTS with dynamic bit sent and the so does the bullet at L53. The third sentence says that in all other cases the bandwidth of the TXOP is from the initial frame and then so does L58 and P84L6” 11/1060r0 proposed the following changes to 11ac D1.0 and it was included in TGac D1.2, and it also resolves CID 2915. 9.19.2.4 Multiple transmission in an EDCA TXOP A TXOP is obtained after a STA transmitting an initial frame successfully receives a response frame. When a TXOP is obtained for a bandwidth that is greater than 20MHz by non-HT duplicate frame exchange, the TXOP holder may transmit PPDUs using CH_BANDWIDTH that are up to and including the bandwidth obtained for the TXOP. During the TXOP, the TXOP holder shall not transmit PPDUs using CH_BANDWIDTH greater than the obtained bandwidth for the TXOP.
