摘要： A method and wireless apparatus are described, whereby a transceiver receives a null data packet announcement (NDPA) frame from a transmitter to initiate channel sounding, and receives a null data packet (NDP) from the transmitter, the NDP following the NDPA frame. A first report field is configured to include beamforming information, and a second report field is configured to include signal to noise ratio (SNR) information. A determination is made as to whether feedback data including the first report field and the second report field is transmitted in a single feedback frame or a plurality of feedback frames. If the feedback data is determined to be transmitted in the plurality of feedback frames, the feedback data is split into a plurality of segments, which is transmitted in a single aggregated medium access control protocol data unit (A-MPDU) including a plurality of MPDUs.
