different from the current trigger frame format defined in 9.3.1.23 TGax Editor to make the changes as in 820 60 34 According to text, an HE STAs reset its OBO couter every time when it obtains the value of OCW from HE AP. Althogh it provides immediate congestion control, it cannot provide higher priority for long waiting STAs unlike conventinal 802.11 channel access. Change the followings "For an initial UL PPDU transmission, when an HE STA obtains the value of OCWmin from the HE AP, it shall set the value of OCW to the OCWmin and shall 'get new random value in the range of 0 and OCWmin, an HE STA sets OBO counter to the random value if it is smaller than the original OBO counter.'(initialize its OBO counter to a random value in the range of 0 and OCWmin.") Rejected The proposed change from the commenter does not provide a mechanism to support his comment. Moreover, for fairness among users, such priority in UL OFDMA-based random access is not beneficial, since the control is on the AP in scheduling a trigger frame for random access (different from channel access). 988 60 44 The illustration of the UL random access procedure in Figure 25-1 should be consistent with the following description "If the OBO counter for an HE STA is smaller than the number of RUs assigned to AID value TBD in a Please make the illustration simple and consistent with the description "If the OBO counter for an HE STA is smaller than the number of RUs assigned to AID value TBD in a Trigger frame, then the HE STA shall decrement its OBO counter to zero.
