摘要： A plurality of beacon data units are generated, and each beacon data unit in the plurality of beacon data units includes an indication that the beacon data unit can be used for transmit beamforming training. The plurality of beacon data units are transmitted via a plurality of antennas during a timeslot reserved for the transmission of beacons. A different beamforming vector is applied to a beamforming network as each beacon data unit is transmitted. In another aspect, a first beamforming training transmission corrupted by a collision is received. A first station to which the first beamforming training transmission corresponds is determined based on the first beamforming training transmission corrupted by the collision. In response to determining the first station, a signal is transmitted to the first station to prompt the first station to transmit a second beamforming training transmission.

摘要： In a method for transmitting a data unit in a wireless communication network, a physical layer (PHY) preamble and a media access control layer (MAC) header are generated. In generating the MAC header, a first address field to include a first address and a second address field to include a second address are generated. The first, not globally unique, address indicates a communication device for which the data unit is intended or a communication device that is transmitting the data unit. The second address field indicates the other one of a communication device for which the data unit is intended or a communication device that is transmitting the data unit. The first address field and the second address field are included in the MAC header. The MAC header omits a globally unique address corresponding to the first address of the first address field.

摘要： In a method of determining an available channel bandwidth in a communication system, wherein the communication system utilizes i) a set of component channels for transmitting data streams and ii) a set of access control channels, and wherein each of at least some of the access control channels partially overlaps, in frequency, at least one of the component channels, whether a primary channel of the access control channels is idle is determined. The primary channel partially overlaps, in frequency, at least a first one of the component channels. That a composite channel includes one or more of the component channels is determined based at least on a determination of whether the primary channel is idle. A signal is caused to be transmitted via the composite channel after determining that the composite channel includes one or more of the component channels.

摘要： A beacon frame corresponding to a unified beacon format is generated. Generating the beacon frame comprises generating a first portion of the beacon frame, wherein the first portion has the same format whether (i) it is determined to transmit a short beacon frame or, (ii) it is determined to transmit a full beacon frame. A second portion of the beacon frame is generated. The second portion corresponds to a first subformat when it is determined to transmit the short beacon frame, and the second portion corresponds to a first subformat when it is determined to transmit the full beacon frame. The first subformat is different than the second subformat. An indication of whether the beacon frame corresponds to the first subformat or the second subformat is included (i) in the beacon frame or (ii) in a physical layer (PHY) header associated with the beacon frame.

摘要： A client station including a transceiver module, a scanning module, and an association module. The transceiver module is configured to transmit and receive data via a frequency band, where the frequency band includes a plurality of channels. The scanning module is configured to simultaneously scan multiple channels of the frequency band at the same time instead of scanning the plurality of channels of the frequency band one channel at a time, and to determine whether one or more access points are available for association in one or more of the multiple channels. The association module is configured to, in response to the scanning module determining that one or more access points are available for association, determine whether to associate with one of the one or more access points determined to be available for association.
