  • Publication number: 20190253227
    Abstract: A first communication device receives an aggregate medium access control data unit (MAC) protocol data unit (A-MPDU) that aggregates multiple MAC protocol data units from a second communication device. The first communication device generates an acknowledgment data unit that includes a length indication that indicates a length of an acknowledgement field and the acknowledgment field of the indicated length. The length of the acknowledgement field is selected from a subset of predetermined lengths, among a set predetermined lengths, that includes multiple predetermined lengths that do not exceed a maximum number of MAC protocol data units that can be included in the A-MPDU. The maximum number of MAC protocol data units is limited by a buffer size negotiated in an acknowledgement setup procedure previously conducted between the first communication device and the second communication device. The first communication device transmits the acknowledgment data unit to the second communication device.
