Method and system for acknowledging the receipt of a transmitted data stream in a wireless personal area network

摘要

A method and system for acknowledging the receipt of a transmitted data stream in a wireless personal area network (WPAN) are disclosed. In one embodiment, a plurality of medium access control (MAC) protocol data units (MPDUs) are transmitted from a transmitting party to a receiving party, and the receiving entity sends a delayed acknowledgment frame to the transmitting party using a bitmap field for each of the fragmented packets instead of using two bytes of an MPDU block for acknowledging each received MPDU. The bitmap field includes a plurality of bitmap values corresponding to the plurality of MPDUs, and each of the plurality of bitmap values is indicative of whether each of the MPDUs is received or not.
