Abstract: The present specification relates to a method for transmitting, by a station (STA), data through channel bonding in a wireless LAN (WLAN) system, and an apparatus therefor. The station therefor receives scheduling information from an access point (AP), wherein the scheduling information includes information on a channel-bonding beacon interval and information on a non-channel-bonding beacon interval. If the station has channel-bonding capability and data to be transmitted through channel bonding, the station can transmit the data on the basis of the channel bonding through the channel-bonding beacon interval.

Abstract: A method for performing a multi-beamforming training and a device using the same are provided. An initiator transmits a first beacon frame for beamforming training on a first channel during a sector sweep and transmits a second beacon frame for beamforming training on a second channel during the sector sweep. The first beacon frame comprises a multi-channel indicator that indicates that beamforming training is performed on the first and second channels.
