摘要： An apparatus and method establish a secure, direct, station-to-station communication between a first station and a second station in a topology (e.g., PBSS) having a central secret holder/provider that allows secure, direct, station-to-station communications and that allows secure station-to-station broadcast communications. The first station and the second station will have previously established a security association (SA) with a topology control point (PCP). The method includes creating pair-wise unique material for the first station. The pair-wise unique material is computed as a function of (i) a known shared secret associated with the PCP, (ii) a first piece of unique data associated with the first station, and (iii) a second piece of unique data associated with the second station. The method includes securely communicating the pair-wise unique material from the first station to the second station.

摘要： A wireless station includes a transceiver configured to wirelessly receive networking frames over a wireless medium, and a channel access counter configured to track a time period and signal that the time period has expired. The time period begins in response to a first networking frame of the networking frames. The first networking frame is addressed to a receiver other than the wireless station. A length of the time period is based on a first length in response to a type of the first networking frame being an acknowledgment frame type. The length of the time period is based on a second length in response to the type of the first networking frame being a data frame type. The transceiver is configured to wait to access the wireless medium until after the channel access counter signals that the time period has expired.

摘要： A method includes receiving, at or from a station STA, a plurality of packets. Each packet includes a set of flag bits, and a MAC header containing at least a first address field specifying a receiver address and a second address field specifying a transmitter address. The method also includes determining whether each set of flag bits indicates that the STA was associated with an AP when the respective packet was generated, and processing the MAC header of each packet. Processing the MAC header of each packet includes processing a third address field in each packet for which it is determined that the respective set of flag bits indicates that the STA was not associated with an AP when the respective packet was generated. The third address field contains a MAC address of the STA.

摘要： A method of operating an access point includes defining a restricted access window during which stations that belong to a same infrastructure basic service set as the access point are not allowed to transmit data frames. The method further includes generating a beacon announcing the restricted access window, and transmitting the beacon to the stations that belong to the same infrastructure basic service set as the access point. The method also includes, during the restricted access window, receiving a poll frame from a first station of the stations that belong to the same infrastructure basic service set as the access point. The method further includes, subsequent to the poll frame, transmitting a data frame to the first station.

摘要： Systems and techniques relating to wireless communications are described. A described technique includes monitoring a group of wireless channels that are useable by at least a first wireless communication device for wireless communications, receiving one or more beacon signals from one or more second wireless communication devices, identifying, within the group of wireless channels, one or more primary channels on which the one or more beacon signals are received, estimating a traffic load for the one or more identified primary channels, determining, based on the estimated traffic load, whether to use as a primary channel for the first wireless communication device, a channel of the one or more identified primary channels or a channel of the group of wireless channels that is separate from the one or more identified primary channels; and selecting the primary channel for the first wireless communication device based on a result of the determining.

摘要： The present disclosure includes systems, apparatuses, and techniques relating to wireless local area network devices. Systems, apparatuses, and techniques include communicating with multiple wireless communication devices to determine characteristics of spatial wireless channels, determining steering matrices based on one or more outputs of the communicating, and transmitting signals that concurrently provide data to the wireless communication devices via different spatial wireless channels. The signals can be spatially steered to the wireless communication devices based on the steering matrices.
