Abstract

A method is provided for communications between a responding station and a requesting station. In a wireless local area network, the responding station receives a null data packet announcement (NDPA) frame and a null data packet (NDP) frame for channel sounding, and a first poll frame, from the requesting station. The NDP frame follows the NDPA frame. In response to the first poll frame, the responding station transmits a first feedback data field including beamforming feedback information and signal to noise ratio (SNR) information to the requesting station. The responding station receives a second poll frame including a segment retransmission bitmap field indicating at least one segment of the first feedback data field from the requesting station. In response to the second poll frame, the responding station transmits a second feedback data field including the at least one segment of the first feedback data field to the requesting station.
