摘要： A wireless network device includes modulation modules, each configured to receive a data stream and modulate the data stream to generate a modulated data stream. A matrix module generates a multiplexing matrix based on channel conditions between the wireless network device and each of a plurality of client stations, and applies the multiplexing matrix to each of the modulated data streams to generate multiplexed data streams. The wireless network device also includes summing modules, each configured to sum at least two of the multiplexed data streams to generate a transmit data stream. A first transmitter transmits a first one of the transmit data streams during a downlink transmission period to a first one of the client stations. A second transmitter transmits a second one of the transmit data streams to a second one of the client stations while the first transmitter transmits the first one of the transmit data streams.

摘要： Systems and methods are provided for processing a payload portion of a received signal in a single carrier mode or a multiple carrier mode based on a portion of the received signal. A single carrier signaling portion is received at a first rate, and whether the payload portion of the signal is a single carrier signal or a multiple carrier signal is detected from the received single carrier signaling portion. The payload portion of the received signal is received at the first rate and demodulated in a single carrier mode if the detecting determines that the payload portion of the received signal is a single carrier signal, and the payload portion of the received signal is demodulated in a multiple carrier mode if the detecting determines that the payload portion of the received signal is a multiple carrier signal.

摘要： A wireless network including client stations and an access point. A first set of client stations transmit uplink user data during a simultaneous uplink transmission period without sensing channel prior to transmitting the uplink user data. A second set of client stations transmit the uplink user data by sensing channel prior to transmitting the uplink user data. The access point (i) services the client stations, (ii) instructs the second set of client stations to not transmit the uplink user data during the simultaneous uplink transmission period, and (iii) receives the uplink user data transmitted from two or more of the first set of client stations during the simultaneous uplink transmission period. The access point sequentially transmits respective acknowledgements to the two or more of the first set of client stations in a non-overlapping manner during the simultaneous uplink transmission period.
