Considering the delay value is chosen number of 4x HE LTFs and the number of HE-SIG-B symbols depending on the HE PPDU format, there may be some risk of intervening frame when waiting the response frame based on Timeout Interval. Moreover, there is no reason to justify all the reason why spec determines the specific values. Since commentor didn’t provide the value considering all issues, this comment fails to identify changes in sufficient detail. The specific wording of the changes that are supposed to satisfy the commenter can not be determined. 14316 aCCAMidTime is defined as 25us Ensure detection Rejected for 11ax devices and it is same capability of 11ax value of aCCAMidTime for 11ac device is same as that aCCAMidTime is basically used to devises. 11ax defines many types of 11ac devices even look back for a secondary channel of OFDM symbol and the number with smaller OFDM CCA which shall be performed of some of 11ax OFDM symbol symbol. within PIFS, DIFS or AIFS. during 25us is smaller than that of 11ac. Ensure detection capability Since commentor didn’t provide of 11ax device is same as that of the value to be specified in the 11ac devices even with smaller spec, this comment fails to identify number of OFDM symbol, changes in sufficient detail.
