摘要： In a method for transmitting channel feedback data from a receiver to a transmitter, channel data for a plurality of orthogonal frequency division multiplexing (OFDM) tones for one or more spatial or space-time streams corresponding to the communication channel is determined. A compressed form of the channel data is determined. Determining the compressed form includes determining a plurality of angle values associated with the one or more spatial or space-time streams and the one or more OFDM tones of the plurality of OFDM tones. For each of the one or more spatial or space time streams, a per-tone signal to noise ratio (PT-SNR) associated with one or more OFDM tone of the plurality of OFDM tones is determined, and an average signal to noise ratio (avg-SNR) is determined by averaging signal to noise ratio (SNR) values corresponding to one or more OFDM tones of the plurality of OFDM tones. A feedback report is generated to include at least i) the plurality of angle values corresponding to the one or more spatial or space-time streams and the one or more OFDM tones, ii) the PT-SNRs corresponding to the one or more spatial or space-time streams and the one or more OFDM tones, and iii) the avg-SNR corresponding to the one or more spatial or space-time streams. The feedback report is included in a data unit to be transmitted from the receiver to the transmitter.

摘要： In a method for generating a data unit conforming to a first communication protocol, a first field and a second field to be included in a preamble of the data unit are generated. The first field includes a first set of one or more information bits that indicate a duration of the data unit and is formatted such that the first field allows a receiver device that conforms to a second communication protocol to determine the duration of the data unit. The second field includes a second set of one or more information bits that indicate to a receiver device that conforms to the first communication protocol that the data unit conforms to the first communication protocol. The first field and the second field are modulated using a modulation scheme specified for a field corresponding to the first field and the second field, respectively, by the second communication protocol.

The preamble includes a first field having information that indicates a duration of the data unit, the first field being formatted such that the first field is decodable by a receiver device that conforms to a second communication protocol but does not conform to the first communication protocol to determine the duration of the data unit based on the first field. Additionally, the preamble is formatted such that a portion of the preamble is decodable by a receiver device that conforms to a third communication protocol but does not conform to the first communication protocol. Also, the preamble is formatted such that a receiver device that conforms to the first communication protocol can determine that the data unit conforms to the first communication protocol. A data portion of the data unit that conforms to the first communication protocol and does not conform to either (i) the second communication protocol or (ii) the third communication protocol is generated.

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.
