摘要： A method for transmitting a subchannel availability for an uplink (UL) multi-user (MU) transmission is described. An availability of one or more subchannels of an orthogonal frequency division multiplex (OFDM) channel are determined by a first communication device for the UL MU transmission. A High Throughput (HT) Control field of a media access control (MAC) header that includes an indication of the determined availability of the one or more subchannels is generated by the first communication device. A MAC protocol data unit (MPDU) that includes the HT Control field is generated by the first communication device. The MPDU is transmitted by the first communication device to a second communication device via the OFDM channel for a subsequent allocation of radio resources for the UL MU transmission by the second communication device.

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： A method for selecting members of a client uplink group is described. An uplink traffic characteristic information signal is received from each of a plurality of communication devices. Multiple communication devices of the plurality of communication devices are selected as members of a client uplink group based at least on traffic information indicated by the respective uplink traffic characteristic information signals. An uplink group definition frame is transmitted to each member of the client uplink group. The uplink group definition frame indicates an uplink multi-user multiple input multiple output (MU-MIMO) transmission schedule for the client uplink group for members of the client uplink group to simultaneously transmit to an access point. The members of the client uplink group are triggered to transmit uplink data frames simultaneously.

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 communication device in a wireless local area network (WLAN) generates a first portion of a wakeup radio (WUR) packet and a second portion of the WUR packet. The first portion of the WUR packet corresponds to a WLAN legacy physical layer (PHY) preamble. Generating the second portion of the WUR packet includes: generating the second portion of the WUR packet to include a WUR packet PHY sync signal. The WUR packet PHY sync signal corresponds to a sync bit sequence with each bit in the sync bit sequence modulated by a sync waveform. The second portion of the WUR packet is generated to also include a PHY data portion and a padding signal. The padding signal corresponds to a padding bit sequence with each bit in the padding bit sequence modulated by the sync waveform. The communication device transmits the WUR packet in the WLAN.

摘要： An access point generates a management communication frame, that includes information indicating network parameters of a wireless communication network, for transmission in an operating channel of the wireless communication network. The operating channel including i) at least one primary component channel used at least for synchronizing with client stations associated with the access point and ii) at least one scanning channel specified, by the first communication protocol, to be used for scanning by client stations not associated with the access point. The access point generates a physical layer data unit to include the management communication frame, and transmits the physical layer data unit in the at least one scanning channel, specified by the first communication protocol, to allow discovery of the wireless communication network by client stations that are not associated with the access point.
