Abstract: The present specification relates to a method for transmitting and receiving signals by a station in a wireless LAN (WLAN) system. More specifically, the present specification proposes a method for providing information on a primary channel and information on a channel for transmitting signals when a station transmits signals by bonding or combining a plurality of channels, and suggests a method for transmitting and receiving signals on the basis of such method for providing information, and an apparatus therefor.

Abstract: A method for beamforming training and a device using the same are provided. The device receives, from an access point (AP), a plurality of beacon frames for a sector sweep at a beacon transmission interval (BTI). At least one of the plurality of beacon frames includes an overload indicator indicating an overload state. The device determines whether to initiate a random backoff in an association beamforming training (A-BFT) following the BTI, on the basis of the overload indicator.

Abstract: A method of transmitting and receiving a signal, which is transmitted by a station in a wireless communication system, is disclosed in the present specification. The method can include the steps of receiving a PPDU and performing beamforming training based on a TRN field of the received PPDU. In this case, a training length field belonging to an L-header field of the PPDU indicates a length of the TRN field from the timing at which the PPDU ends in reverse order and a length field belonging to the L-header field of the PPDU can indicate a length resulted from subtracting the length of the TRN field indicated by the training length field from a length of the PPDU after the L-header field.

Abstract: Provided are a method and apparatus for performing beamforming training in a wireless local area network. A responder receives a plurality of beacon frames in a plurality of TX sectors from an initiator during a transmission (TX) beamforming (BF) interval. The responder transmits a first sector sweep feedback for a first array antenna to the initiator during a reception (RX) beamforming (BF) interval. The first sector sweep feedback comprises a first antenna ID indicating a first array antenna and a first TX ID indicating a TX sector selected for the first array antenna from the plurality of TX sectors.
