US 2018/0026691 A1 · METHOD OF TRANSMITTING AND RECEIVING SIGNAL IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR

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.

Dependent claims

A method of transmitting and receiving a signal by a station (STA) in a wireless communication system, the method comprising:

receiving a PPDU (physical protocol data unit);
and
performing beamforming training based on a TRN (training) field of the received PPDU,
wherein a training length field included in an L-header (legacy header) field of the PPDU indicates a length of the TRN field from the end of the PPDU in reverse order, and
wherein a length field included in the L-header field of the PPDU indicates a length obtained by subtracting the length of the TRN field indicated by the training length field from a length of the PPDU after the L-header field.
