Abstract: When an AP (access point) performs sounding to transmit a frame to one or more STAs using a beamforming scheme in a wireless LAN (WLAN) system, the AP receives a beamforming feedback, which is generated based on measurement of a specific signal transmitted by the AP in a manner that the one or more STAs group a prescribed number of tones according to a tone grouping element (Ng). In this case, the Ng is configured by a multiple of 4.
