摘要： A first communication device receives a physical layer (PHY) data unit from a second communication device. The PHY data unit includes multiple medium access control (MAC) data units aggregated in an aggregate MAC data unit. The first communication device generates an acknowledgment data unit to acknowledge receipt of the multiple MAC data units. The acknowledgment data unit includes (i) a length indication that indicates a length of an acknowledgement field, and (ii) the acknowledgment field of the indicated length. The acknowledgement field includes respective acknowledgement information for the multiple MAC data units. The first communication device transmits the acknowledgment data unit to the second communication device.

摘要： A communication device determines, in connection with a prior uplink multi- user (UL MU) communication in which the communication device participated, whether the communication device is to use one or more first channel access parameters, or one or more second channel access parameters for accessing a communication medium for a single user (SU) transmission by the communication device, where using the one or more first channel access parameters is associated with a greater probability of obtaining access to the communication medium as compared to using the one or more second channel access parameters. Depending on the determination made, the communication device uses the one or more first channel access parameters, or the one or more second channel access parameters to attempt to access the communication medium. In response to accessing the communication medium, the communication device transmits the SU transmission via the communication medium.

摘要： A first access point (AP), which is associated with one or more first client stations, generates an announcement frame that announces a coordinated multi-user (MU) transmission involving multiple APs including the first AP and one or more second APs. Each of the second APs is associated with a respective one or more second client stations. The announcement frame is generated to indicate respective one or more frequency resource units (RUs) allocated to the one or more second APs for the coordinated MU transmission. The first AP transmits the announcement frame to the one or more second APs to initiate the coordinated MU transmission, and participates in the coordinated MU transmission while the one or more second APs also participate in the coordinated MU transmission.

摘要： A method for acknowledging a first medium access control (MAC) service data unit (MSDU) is described. A first aggregate MAC protocol data unit (A-MPDU) of a first orthogonal frequency division multiple access (OFDM A) data unit is received at a first communication device from a second communication device. The first A-MPDU includes a first fragment of a plurality of fragments of the first MSDU. A second A-MPDU of a second OFDMA data unit is received at the first communication device from the second communication device. The second A-MPDU includes a second fragment of the plurality of fragments and the second fragment is an end fragment of the plurality of fragments. A fragment acknowledgment data unit is generated by the first communication device to acknowledge receipt of each of the plurality of fragments of the first MSDU. The fragment acknowledgment data unit is caused to be transmitted to the second communication device.

摘要： A first communication device determines whether a second communication device is in a power save mode with respect to a first communication link among a plurality of communication links that correspond to respective frequency segments, and determines whether the second communication device is in a power save mode with respect to a second communication link among the plurality of communication links. The second communication device is permitted to be in the power save mode with respect to the second communication link when the second communication device is not in the power save mode with respect to the first communication link, and vice versa. The first communication device communicates with the second communication device in accordance with the power save modes of the second communication device with respect to the first and second communication links.

摘要： A beamforming training packet is transmitted from a first communication device to multiple second communication devices. A trigger frame is generated at the first communication device to trigger an uplink orthogonal frequency division multiple access (OFDMA) transmission of beamforming training feedback from at least some of the multiple second communication devices. After transmission of the beamforming training packet by the first communication device, the trigger frame is transmitted to the at least some of the multiple communication devices. The uplink OFDMA transmission is then received at the first communication device. The uplink OFDMA transmission includes respective beamforming training feedback packets generated based on the beamforming training packet by respective ones of the at least some of the multiple second communication devices. The respective beamforming training feedback packets are simultaneously transmitted by the at least some of the multiple second communication devices.

摘要： In a method for generating a data unit, it is determined whether the data unit is to be transmitted using single carrier (SC) modulation or orthogonal frequency division (OFDM) modulation. When it is determined that the data unit is to be transmitted using SC modulation, a header field of the data unit is generated using a first technique to indicate that the data unit conforms to a first protocol and/or whether the data unit conforms to a first PHY mode or a second PHY mode of the first protocol. When it is determined that the data unit is to be transmitted using OFDM modulation, the header field is generated using a second technique to indicate that the data unit conforms to the first protocol and/or whether the data unit conforms to the first PHY mode or the second PHY mode of the first protocol.
