Summary:Provided are a method for beamforming training and an apparatus using the same. An STA receives a beacon frame from an AP during a BTI. The STA transmits SSW frames during an A-BFT. The beacon frame comprises an A-BFT length indicating the number of a plurality of SSW slots included in the A-BFT, a FSS field indicating the number of the SSW frames allowed in one SSW slot among the plurality of SSW slots, and information about the type of the SSW frames used in one SSW slot. The information about the type of the SSW frames indicates that the SSW frames are determined to be one from among first type SSW frames and second type SSW frames. The second type SSW frames have a smaller size than that of the first type SSW frames. If the SSW frames are determined to be the second type SSW frames, the FSS field indicates the number of the second type SSW frames that can be transmitted in one SSW slot.
