    Abstract: Provided are a method and apparatus for transmitting a feedback frame by performing multi input multi output (MIMO) beamforming procedure in a wireless local area network (WLAN) system. Specifically, a first station (STA) generates the feedback frame based on the MIMO beamforming procedure. The first STA transmits the feedback frame to a second STA. The feedback frame includes a feedback subcarrier for a predetermined frequency band. A first subcarrier transmitted first in the feedback subcarrier and a second subcarrier having subcarrier indices −2 and 2 are statically transmitted. The first subcarrier is configured as a left edge subcarrier or right edge subcarrier of the predetermined frequency band. A subcarrier index of a third subcarrier included in the feedback subcarrier is determined based on a grouping value which is a subcarrier interval. The third subcarrier is a subcarrier excluding the first subcarrier and the second subcarrier from the feedback subcarrier. The grouping value is dynamically changed based on channel state information.

    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: 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.
