Abstract: A channel sounding method in a wireless local area network (WLAN) system and an apparatus supporting the same are provided. A method of performing a sounding operation by an access point (AP) in a wireless local area network (WLAN) includes: generating a beamforming report (BR) poll frame including a sounding sequence; transmitting the BR poll frame to a station (STA); and selectively performing transmission beamforming on the station according to whether or not the BR frame is received from the station before a predetermined timeout. Transmission of an erroneous BR frame in case that a beam receiver fails to receive an null data packet announcement (NDPA) and an null data packet (NDP) is eliminated and a degradation of transmission efficiency is prevented.
