Abstract

Embodiments disclosed herein address the need in the art for enhanced block acknowledgement. In one embodiment, a receiver indicates a decoding delay for a maximum size aggregate frame in Block Ack negotiation, which may be used by a transmitter to determine to which Block Ack Request a Block Acknowledgement is responsive. In another embodiment, a Transmission Sequence Number (TSN) may be included in a Block Ack Request. The receiver includes the TSN in the corresponding Block Ack response. This allows the transmitter to determine which frames are "in transit." The TSN may be used to identify blocks. In another embodiment, a TSN may be associated with one or more transmitted frames. While, the TSN is not transmitted with the Block Ack Request, the transmitter may determine which TSN corresponds with a Block Ack response in accordance with acknowledgements contained therein. Combinations of these techniques may be deployed. Various other aspects are also presented.
