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.

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 method is described. A block allocation that indicates a plurality of contiguous tone blocks of a wireless local area network communication channel is selected for a multi-user, multiple input multiple output (MU-MIMO) orthogonal frequency division multiple access (OFDMA) data unit. A contiguous tone block corresponds to a respective device set having at least one communication device. Respective spatial stream allocations are selected, for at least some of the blocks, that indicate a number of spatial streams for the corresponding block of the data unit. The number of streams of a block is equal to a number of communication devices of the device set that corresponds to the block. A first field is encoded and transmitted to indicate the selected block allocation and the selected spatial stream allocations. A second field is encoded and transmitted to indicate a respective device identifier for each communication device of the respective device sets.
