Abstract: A method for beamforming training and a device using the same are provided. A station (STA) receives a beacon frame from an access point (AP) during a beacon transmission interval (BTI). The beacon frame includes information on a sector sweep (SSW) frame type used in at least one of a plurality of SSW slots. During association beamforming training (A-BFT), the STA transmits the SSW frame according to the SSW frame type from an SSW slot, among a plurality of SSW slots, having succeeded in a random backoff.

Abstract: A beamforming training using a polarization in a wireless local area network is provided. An initiator receives a response frame from the responder. The response frame includes information about a polarization type selected by the responder. The initiator transmits a sector sweep message to the responder using the selected polarization type through all sectors during a sector sweep.

Abstract: A method for the multiple beamforming training and an apparatus using the same are provided. An initiator determines a candidate sector to be used for a transmission during a sector sweep. After the initiator exchanges with a responder an information request frame and an information response frame about the multiple beamforming training through the candidate sector, the responder performs a plurality of beam refinement protocol (BRP) processes using a plurality of polarized channels through the candidate sector.

Abstract: Provided are a method and apparatus for performing beamforming training in a wireless local area network. The apparatus receives a plurality of beacon frames for sector sweep in a beacon transmission interval (BTI) from an access point (AP). At least one beacon frame of the plurality of beacon frames includes overload information which indicates an overload state. The apparatus performs a random backoff on a plurality of channels during association-beamforming training (A-BFT) consequent to the BTI based on the overload information.
