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： Embodiments described herein provide a method for resource unit signaling with reduced data bits in a wireless local area network. At a wireless transceiver, a data frame may be obtained for transmission. The data frame includes a first preamble portion and a second preamble portion compliant with a wireless local area network communication protocol. When an available resource unit for transmitting the data frame is less than an allowed bandwidth, the first preamble portion and the second preamble portion may be configured with resource unit signaling bits. When the available resource unit is greater than or equal to the allowed bandwidth, the resource unit may be virtually divided into a plurality of channels. At least one of the first preamble portion and the second preamble portion may be configured with a first number of bits representing a number of users spatially multiplexed on a channel from the plurality of channels.

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.
