摘要： A plurality of beacon data units are generated, and each beacon data unit in the plurality of beacon data units includes an indication that the beacon data unit can be used for transmit beamforming training. The plurality of beacon data units are transmitted via a plurality of antennas during a timeslot reserved for the transmission of beacons. A different beamforming vector is applied to a beamforming network as each beacon data unit is transmitted. In another aspect, a first beamforming training transmission corrupted by a collision is received. A first station to which the first beamforming training transmission corresponds is determined based on the first beamforming training transmission corrupted by the collision. In response to determining the first station, a signal is transmitted to the first station to prompt the first station to transmit a second beamforming training transmission.

摘要： Aspects of the disclosure provide an apparatus that includes a transceiver circuit and a processing circuit. The transceiver circuit is configured to receive a trigger signal this is transmitted by another apparatus. The trigger signal triggers transmissions by a first group of apparatuses including the apparatus, and defers transmissions by a second group of apparatuses that interfere the transmissions by the first group of apparatuses. The processing circuit is configured to, in response to the trigger signal, generate a frame with a first preamble structure that is different from a second preamble structure that is used by the second group of apparatuses, and provide the generated frame to the transceiver circuit for transmission.

摘要： A first communication device generates a multi-user (MU) physical layer (PHY) data unit having independent data for multiple second communication devices. The first communication device also generates respective control frames to prompt second communication devices to transmit an orthogonal frequency division multiple access (OFDMA) PHY data unit to acknowledge that the second communication devices received the MU PHY data unit. The MU PHY data unit and the respective control frames are transmitted to the multiple second communication devices. The first communication device receives the OFDMA PHY data unit from at least some of the second communication devices. The first communication device processes the OFDMA PHY data unit to determine whether the multiple second communication devices received the MU PHY data unit.

摘要： A method for generating a physical layer (PHY) data unit for transmission via a communication channel is described where the PHY data unit conforms to a first communication protocol. Orthogonal frequency division multiplexing (OFDM) symbols for a data field of the PHY data unit are generated according to a range extension coding scheme that corresponds to a range extension mode of the first communication protocol. A preamble of the PHY data unit is generated, the preamble having i) a first portion that indicates a duration of the PHY data unit and ii) a second portion that indicates whether at least some OFDM symbols of the data field are generated according to the range extension coding scheme. The first portion of the preamble is formatted such that the first portion of the preamble is decodable by a receiver device that conforms to a second communication protocol, but does not conform to the first communication protocol, to determine the duration of the PHY data unit based on the first portion of the preamble. The PHY data unit is generated to include the preamble and the data field.
