摘要： An access point manages a first wireless local area network (WLAN) in a 6 GHz radio frequency (RF) band and ii) a second WLAN operating in another RF band. The access point generates a physical layer (PHY) data unit to include a management frame having i) first information indicating first network parameters of the first WLAN, and ii) second information indicating second network parameters of the second WLAN. The AP transmits the PHY data unit in the other RF band to provide, to any client stations that are operating in the other RF band and that are also capable of operating in the 6 GHz band: the first information indicating the first network parameters of the first WLAN operating in the 6 GHz RF band to assist the any client stations that are operating in the other RF band with joining the first WLAN operating in the 6 GHz RF band.

摘要： An access point (AP) generates a multi-user request to send (MU-RTS) frame for protecting a channel bandwidth during a communication exchange, and transmits the MU-RTS frame in multiple duplicate first packets in respective communication subchannels that span the channel bandwidth. Each first packet has a first packet format that conforms to a legacy protocol. The AP receives multiple clear-to-send (CTS) frames from multiple client stations via respective communication subchannels that span the channel bandwidth. The AP generates a trigger frame configured to prompt the multiple client stations to transmit respective data to the AP. After transmitting the multiple first packets, the AP transmits the trigger frame in one or more second packets that span the channel bandwidth and that conform to a second packet format defined by a non-legacy protocol. The AP receives, from the multiple client stations, data frames that are responsive to the trigger frame.

摘要： A first access point (AP), which is associated with one or more first client stations, receives an announcement frame from a second AP that is associated with one or more second client stations. The announcement frame announces a coordinated multi-user (MU) transmission involving at least the first AP and the second AP, includes an indicator of a frequency resource unit (RU) allocated to the first AP for the coordinated MU transmission. The first AP participates in the coordinated MU transmission using the frequency RU indicated by the announcement frame while the second AP also participates in the coordinated MU transmission.

摘要： A first portion of a physical layer (PHY) preamble of a PHY data unit is generated for transmission via a communication channel that comprises a plurality of sub-channels. A first portion of the PHY preamble is generated to include a legacy portion and a plurality of first non-legacy signal fields spanning the respective sub-channels. A second portion of a PHY preamble that immediately follows the first portion of the PHY preamble of the PHY data unit is generated to include: a non-legacy short training field spanning all sub-channels in the plurality of sub-channels, a plurality of non-legacy long training fields immediately following the non-legacy short training field, each non-legacy training field spanning all sub-channels in the plurality of sub-channels, and a second non-legacy signal field immediately following the plurality of non-legacy long training fields, the second-legacy signal field spanning all sub-channels in the plurality of sub-channels.

摘要： A first communication device generates and transmits a first communication frame corresponding to a request to participate in a block acknowledgment procedure. The first communication frame includes: a first field indicating a number of buffers requested to be allocated at a second communication device for buffering data units to be transmitted by the first communication device, and a second field indicating a first maximum bitmap length supported by the first communication device. The first communication device receives a second communication frame corresponding to a response to the first communication frame. The second communication frame includes: a third field indicating a number of buffers allocated at the second communication device for buffering the data units transmitted by the first communication device, and a fourth field indicating a second maximum bitmap length supported by the second communication device. The first communication device performs the block acknowledgment procedure in accordance with the second maximum bitmap length.

摘要： A communication device determines whether simultaneous transmissions in a first frequency segment and a second frequency segment are to be synchronized in time. In response determining that simultaneous transmissions in the first frequency segment and the second frequency segment are to be synchronized in time, the communication device transmits a first packet in the first frequency segment beginning at a first time, and transmits a second packet in the second frequency segment beginning at the first time. In response to determining that simultaneous transmissions in the first frequency segment and the second frequency segment are to be unsynchronized in time, the communication device transmits a third packet in the first frequency segment beginning at a second time, and transmits a fourth packet in the second frequency segment beginning at a third time that is different than the second time.

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 generates a first packet and a second packet. The first packet includes a first physical layer (PHY) preamble having: a first legacy signal field (L-SIG) having first duration information that indicates a first duration of the first packet; and first non-legacy signal field information having first modulation information that indicates a first modulation used in the first packet. The second packet includes a second PHY preamble having: a second L-SIG having second duration information that indicates a second duration of the second packet, wherein the second duration is different than the first duration; and second non-legacy signal field information having second modulation information that indicates a second modulation used in the second packet, wherein the second modulation is different than the first modulation. The communication device simultaneously transmits the first packet in a first frequency segment and the second packet in a second frequency segment.

摘要： A preamble of physical layer (PHY) data unit includes a first legacy portion and a first non-legacy portion that follows the first legacy portion. The first non-legacy portion includes i) a first orthogonal frequency division multiplexing (OFDM) symbol that immediately follows the first legacy portion and that is modulated using binary phase shift keying (BPSK), and ii) a second OFDM symbol that immediately follows the first OFDM symbol and that is modulated using BPSK modulation rotated by 90 degrees (Q-BPSK). The modulation of the first and second OFDM symbols indicates to a receiver device that conforms to a first communication protocol that the data unit conforms to the first communication protocol. The first OFDM symbol being modulated using BPSK modulation causes a receiver device that conforms to a second communication protocol to determine that the PHY data unit conforms to a third communication protocol.
