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.
