Abstract: An orthogonal frequency division multiple access (OFDMA) frame includes a 256 tone payload. The 256 tone payload may consist of either 234 data tones when the payload is carried in a downlink transmission. The 256 tone payload may consist of 216 data tones when the payload is carried in an uplink transmission. In addition, the OFDMA frame may include one or more resource units (RUs). Each of the one or more RUs may consist of either an integer multiple of 26 data tones or an integer multiple of 24 data tones and 2 pilot tones. Another embodiment OFDMA frame comprises a symbol-based RU (SRU) that may include an integer multiple of 2 pilots tones and either an integer multiple of 24 data tones or an integer multiple of 26 data tones.

Abstract: The present invention discloses an access point, a station, and a beacon frame sending method and system, relates to the communications field, and resolves a problem of relatively large network overheads caused for purposes of ensuring that in a WLAN system having multiple channels, a STA can quickly access a network. A specific solution is as follows: A first sending unit sends a beacon indication frame on each subchannel of N subchannels, where the beacon indication frame is used to indicate configuration information of a beacon frame; and a second sending unit sends the beacon frame on at least one first subchannel. The present invention is applied to a beacon frame sending process.

Abstract: Embodiments provide a method for accessing a wireless local area network, a station, and an access point. The method includes: receiving, by a station, a beacon or a probe response from an access point, where the beacon or the probe response carries configuration version information; and executing, by the station, a GAS query according to the configuration version information carried in the beacon or the probe response. In embodiments, the access point sends the configuration version information to the station, so that the station executes the GAS query according to the configuration version information.

Abstract: An embodiment OFDMA frame includes a header with signal (SIG) fields that are encoded at different sampling rates than one another. In one example, a first signal field is encoded at a 64 point fast frequency transform (FFT) sampling rate, and the second SIG field is encoded at a 256 point FFT sampling rate. The first SIG field may carry parameters for decoding the second SIG field, and the second SIG field may carry resource allocation information for a payload of the OFDMA frame. The first SIG field may carry an identifier of an access point that transmits the OFDMA frame.
