Revise - TGmd editor to make changes as shown in that are marked with CID 1063. These changes clarify the meaning of the estimated air time fraction field as only applying to transmissions to the STA that is receiving the element with this field. The description of the field and the associated behavorial description indicate that there are restrictions on what is included in the air time fraction (i.e. data) and the overhead needed to transmit that data. Additional inserted text notes that the algorithm to determine this value is beyond the scope of the standard. 1064 Emily Qi "The Estimated Air Time Fraction subfield is 8 bits in length and contains an unsigned integer that represents the predicted percentage of time...." . The Air time allocation by AP for a specific STA may include additional assumptions with regard to airtime fairness logic. This definition does not take this into account. Also, how to derive this "percentage of time" need to be specified. Otherwise, the estimated throughput service is meaningless and vendors may provide disinformation.

These changes note that the algorithm to determine this value is beyond the scope of the standard. The commenter is effectively asking for a limit on the accuracy of the delivered value, and the group is unwilling to supply such a requirement as it might place too much constraint on the possible algorithms from which to choose and might not be capable of ensuring a constant level of accuracy through different operating conditions. 1 2 1
