摘要： The present invention relates to methods for interference cancellation between terminals in a full-duplex radio (FDR) system and apparatuses supporting the same. A method for cancelling interference between terminals in a wireless access system supporting a full-duplex radio (FDR) system, as an aspect of the present invention, may comprise the steps of: receiving, by a first terminal, reference signal information including information for configuring an interference reference signal from a base station; receiving the interference reference signal from a second terminal; obtaining, by the first terminal, interference channel information with regard to an interference channel between the first terminal and the second terminal on the basis of the interference reference signal; and transmitting by beamforming uplink data to the base station on the basis of the interference channel information by the first terminal. In this case, the first terminal is supported by the FDR system and the second terminal supports the half-duplex radio (HDR) system, and a resource area transmitting uplink data by the first terminal can be configured to match a resource area receiving downlink data by the second terminal.
