摘要： A set of channels is scanned, each channel in the set having a first bandwidth. When it is determined that one or more channels in the set of channels are not being utilized by one or more other wireless communication systems, a channel not being utilized is selected as a primary channel for a wireless communication system. When it is determined that all channels in the set of channels are being utilized by one or more other wireless communication systems, (i) a channel in the set that is aligned with a primary channel of another wireless communication system is selected as the primary channel, or (ii) a channel in the set that overlaps with a secondary channel of another wireless communication system is selected as the primary channel, where the secondary channel of the other wireless communication system has a bandwidth greater than the first bandwidth.

摘要： A method for generating signals to be transmitted within a BSS channel, where a set of component channels is collectively coextensive with the BSS channel, includes determining that a first duplicate, in frequency, of a low bandwidth mode data unit will be located at an edge of the BSS channel. Each duplicate includes OFDM tones and has a bandwidth less than the narrowest channel of the component channels. The OFDM tones in each duplicate include one or more data tones, one or more pilot tones, and one or more guard tones. The method also includes generating a transmission signal comprising the duplicates, at least in part by scaling down at least one data tone, and/or zeroing out at least one data tone, of the first duplicate in response to determining that the first duplicate will be located at an edge of the BSS channel.

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： Training data for a first training session is generated to include a first data unit, the first data unit having a field that specifies a first number of beamforming training data units that can be communicated during a second training session to occur after the first training session. The training data including the first data unit is transmitted to a second device during the first training session. A second data unit received from the second device is processed to determine whether a request for the second device to participate in the second training session was accepted by the second device based on a first field of the second data unit. In response to determining that the request to participate in the second training session was accepted by the second device, the first number of beamforming training data units are transmitted during the second training session.

摘要： In a method for generating a physical layer (PHY) data unit for transmission via a communication channel, the PHY data unit is generated according to a first PHY format when the PHY data unit is to be transmitted in a regular mode, wherein the first PHY format corresponds to a first bandwidth. The PHY data unit is generated according to a second PHY format when the PHY data unit is to be transmitted in an extended range mode, wherein the second PHY format corresponds to a second bandwidth. A preamble of the PHY data unit is modulated such that a receiving device can auto-detect whether the PHY data unit was transmitted at the first bandwidth or the second bandwidth.
