Abstract
A wireless local area network includes transmission of data packets between endpoints in which packet frames are divided into sub-frames. On reception of a frame, the integrity of each individual sub-frame is checked. Sub-frames that pass the integrity check are acknowledged and retransmission is requested only for sub-frames that failed the integrity check. Consequently, only the affected sub-frames require retransmission instead of the whole frame.
