摘要: An access point establishes a first communication channel as a primary channel of the access point, and transmits wakeup radio (WUR) beacon frames via a second communication channel, different than the first communication channel, that corresponds to a WUR primary channel. The access point negotiates, with a client station, a third communication channel, different than the first and second communication channels, via which the access point is to transmit wakeup frames for the client station. The access point generates a wakeup frame for transmission to the client station via the third communication channel, generates a wakeup packet to include at least the wakeup frame, and transmits the wakeup packet, including transmitting the wakeup frame to the client station via the third communication channel.

摘要: A first communication device determines which one or more types of feedback information, from among a plurality of types of feedback information associated with a range measurement exchange session, a second communication device is to provide to the first communication device in a feedback packet transmitted as part of the range measurement exchange session. The first communication device transmits to the second communication device one or more indications of the determined one or more types of feedback information that the second communication device is to provide to the first communication device in the feedback packet. The first communication device performs the range measurement exchange, including receiving the feedback packet from the second communication device, wherein the feedback packet includes the determined one or more types of feedback information.

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 communication device assigns a first basic service set (BSS) color identifier (ID) to a first communication link among multiple communication links corresponding to multiple frequency segments, and assigns a second BSS color ID to a second communication link among the multiple communication links. The communication device uses the first BSS color ID when communicating via the first communication link, and uses the second BSS color ID when communicating via the second communication link.

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 one or more respective sets of communication parameters to be used by the one or more second APs for communicating with the respective one or more second client stations during 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 communication device performs a first backoff operation to determine when the communication device can begin a first simultaneous transmission via multiple channel segments. The first backoff operation includes counting down a first backoff timer in connection with a first channel segment. In response to the first backoff timer expiring, the communication device performs the first simultaneous transmission via the multiple channel segments. After performing the first simultaneous transmission via the multiple channel segments, the communication device performs a second backoff operation to determine when the communication device can begin a second simultaneous transmission via the multiple channel segments. The second backoff operation includes counting down a second backoff timer in connection with a second channel segment. In response to the second backoff timer expiring, the communication device performs the second simultaneous transmission via the multiple channel segments.

摘要: An access point (AP) allocates a broadcast resource unit (RU), and ii) one or more other RUs for a multi-user physical layer protocol data unit (MU PPDU). The AP generates the MU PPDU to include i) a physical layer (PHY) preamble, and ii) a management medium access control layer (MAC) frame in the broadcast RU. When the AP device is allowing unassociated stations to associate with the AP device, the AP device sets a station identifier in the PHY preamble corresponding to the broadcast RU to a first value that indicates the AP device is allowing unassociated stations to associate with the AP device. When the AP device is not allowing unassociated stations to associate with the AP device, the AP device sets the station identifier to a second value that indicates the AP device is not allowing unassociated stations to associate with the AP device.
