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.
