1. A method for estimating a self-interference (SI) channel in a wireless access system supporting full duplex radio (FDR) communication, the method performed by an evolved Node-B (eNB) and the method comprising:

  • transmitting a channel signal including a first cyclic shift variable allocated to a user equipment (UE);

    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.
