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.
