Abstract: The present invention relates to a wireless access system supporting a full duplex radio (FDR) transmission environment. A method by which a first UE receives a signal from a base station in a wireless access system supporting FDR transmission, according to one embodiment of the present invention, can comprise the steps of: receiving a first reference signal from the base station; calculating first channel information on self-interference by using the first reference signal; receiving a second reference signal from the base station, and receiving a third reference signal from a second UE at the same time as the second reference signal; calculating second channel information from which the self-interference is cancelled, on the basis of the second reference signal, the third reference signal and the first channel information; and receiving the signal by using the second channel information and third channel information on a channel receiving the signal.
