ABSTRACT:
Fast block acknowledgment generation is provided, via a receiving station, for a plurality of received frames to accommodate latency-sensitive data applications. The fast block acknowledgment generation includes receiving a frame of the plurality of received frames including a transmitter address, a quality of service (QoS) value, and a sequence number. A match to the transmitter address and the QoS value is conducted under a concurrent search to expedite access to a block acknowledgement (ACK) structure, the match provides an index to the block ACK structure. When a block ACK agreement exists that corresponds to the transmitter address and the QoS value, the block ACK structure is accessed based upon the index and storing an acknowledgement state for the received frame in a bitmap of the block ACK structure, and when receipt of the plurality of frames is complete, generating, queuing, and transmitting of a block ACK frame based upon the ACK policy field of the received frame.
