Abstract: The present invention provides methods for estimating self-interference in a full-duplex radio (FDR) system using a reference signal to which a cyclic shift is applied, and apparatuses supporting the same. According to one embodiment of the present invention, a method for estimating a self-interference (SI) channel, by a base station, in a wireless access system supporting wireless FDR communication comprises the steps of: transmitting a channel signal including a first cyclic shift variable allocated to a terminal; transmitting a downlink (DL) self-interference reference signal (SI-RS) for estimating the SI channel generated on the basis of a second cyclic shift variable; receiving the DL SI-RS; receiving an uplink (UL) SI-RS generated on the basis of the first cyclic shift variable; and estimating the SI channel using the DL SI-RS and the UL SI-RS.
