Abstract
Wireless devices, methods, and computer readable media for fragmentation and aggregation with block acknowledgement in a wireless local-area network. A wireless communication device for fragmentation may include circuitry configured to fragment a media access control (MAC) service data unit (MSDU) into a plurality of MAC protocol data units (MPDU). The circuitry may be configured to set a sequence number field of each of the MPDUs of the plurality of MPDUs, where the sequence number indicates the relative position of the MPDU in a transmission stream of MPDUs, and set a position indication field of each of the MPDUs of the plurality of MPDUs to indicate a position of each MPDU in the plurality of MPDUs. The position indication field may indicate whether each MPDU is a start, a middle, or a last MPDU. The circuitry may be configured to aggregate MSDUs and fragments of MSDUs.
