12019 Yee 27.9.2.l 291.30 P. 290 line 30-61 are defining spatial reuses, here the spec should also require the PPDU received is not from a SRG STA. As provided in comment. See 11-17-LLLLrY 14116 Yuichi 27.9.2.1 291.33 In order to allow efficient use of SR resource, STA should be allowed to subtract the time it took to determine that the received PPDU is an inter-BSS PPDU from its BO timer. This is especially important to effectively utilize the SR resource, because by the time the BO expires in many cases the OBSS PPDU would be already be finished. Add "If the primitive is issued before the end of the PPDU, the Backoff counter of the STA may be decremented by the time it took from the beginning of the PPDU until the primitive was issued" See 11-17-LLLLrY Yuichi 27.9.2.1 291.34 Even if the TXOP is limited to the duration of the PPDU, the STA is allowed to send an SR PPDU that extends beyond the end of the TXOP. This SR PPDU will collide with the response of the MU transmission. Add description as to how the SR PPDU will not collide with response to MU transmission. See 11-17-LLLLrY 14278 27.9.2.1 291.34 This rule limits the TXOP obtained by the OBSS_PD mechanism to the duration of the HE MU PPDU to prevent interfering. According to IEEE802.11 2016, start of PPDU shall be within TXOP but end of PPDU could exceed the end of TXOP so limitation of TXOP is not enough and the duration of PPDU must be limited as well. Add "and the duration of transmitting PPDU shall not exceed the end of the PPDU" after "the TXOP shall be limited to the duration of the PPDU" See 11-17-LLLLrY
