Claim of US Patent No. 10,397,950

1. A method of managing communication on a wireless channel on which a first wireless communication device (WCD) and second WCD engage in a sequence of N data-ACK exchanges with each other, wherein N>1, wherein the sequence includes one or more non-final data-ACK exchanges and ends with a final data-ACK exchange, and wherein each data-ACK exchange consists of the first WCD transmitting application data to the second WCD and the second WCD transmitting a corresponding acknowledgement (ACK) message to the first WCD, the method comprising:transmitting within at least one of the one or more non-final data-ACK exchanges an indication of how many data-ACK exchanges remain in the sequence, wherein the indication comprises a count of how many data-ACK exchanges remain in the sequence, whereby the indication of how many data-ACK exchanges remain in the sequence can help a third WCD manage how many times to refrain from transmission on the channel,
wherein transmitting in the data-ACK exchange the indication of how many data-ACK exchanges remain in the sequence comprises at least one feature selected from the group consisting of (i) the first WCD transmitting in a header of the application data of the data-ACK exchange the indication of how many data-ACK exchanges remain in the sequence and (ii) the second WCD transmitting in a header of the ACK message of the data-ACK exchange the indication of how many data-ACK exchanges remain in the sequence.
