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.

Abstract: A system includes a first transmitter, a second transmitter, and a legacy receiver. The first transmitter transmits information via a first channel to the legacy receiver. The second transmitter transmits a time-shifted version of the information via a second channel to the legacy receiver. The legacy receiver combines the information received via the first channel and the time-shifted information received via the second channel to provide combined information. The legacy receiver processes the combined information as though it is received via a single channel.

Abstract: A system and method of throughput-based transmission rate adaptation for wireless transmissions is provided. An adapted transmission rate is determined based on transmission feedback from previous wireless frame transmissions. The adapted transmission rate is determined by comparing nominal throughputs derived from packet success rate (PSR) estimates at the current rate and other rates, such that the adapted transmission rate chosen is one that maximizes the nominal throughput. The PSR estimates can include those associated with the current rate, a fallback rate, and other rates. The PSR estimates are updated after each frame transmission. The PSR estimates can be saved and used for calculating future estimates, and they can also be time-stamped so as not to use them if they are older than a predetermined age.

When at least one legacy device is within the proximal region, a frame is formatted to include a preamble field, a signal field, and a data field. Further, the uncoded bits are encoded according to a coding format. The coding format is determined according to bits in the preamble and applicable sub-field lengths.
