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： An access point, AP, device determines a set of basic service set identifiers, BSSIDs. Each BSSID includes a same group of most significant bits (MSBs) and a different group ofnleast significant bits, LSBs. The AP device assigns respective BSSIDs from the set of BSSIDs to multiple virtual APs, and designates one of the assigned BSSIDs as a reference BSSID that corresponds to a transmitter address, TA (510) for frames intended for client stations associated with more than one virtual AP. The AP device generates and transmits a management frame (500) that includes i) a header with a TA field set to one of the assigned BSSIDs (510), and ii) a frame body with a plurality of fields that includes a) a first field (568) set to n, and b) a second field (570) set to the n LSBs of the reference BSSID. The TA field, the first field, and the second field in the management frame indicate the reference BSSID to a client station that receives the management frame.
