Abstract
A method for channel sounding in a wireless local area network (WLAN) system and apparatus for the same is disclosed. An access point (AP) to perform the method for channel sounding broadcasts information on a restricted access window (RAW) for channel sounding included in a beacon, and transmits null data packets (NDP) for channel estimation in the RAW to a station (STA). The STA estimates channel information based on the NDPs, and transmits the estimated channel information to the AP.
