Abstract
A method for removing a self-interference signal by a device supporting an FDR mode can further comprise the steps of: transmitting a signal to a counterpart node in a predetermined time interval; generating, in an RF stage of the device, a residual self-interference signal after removal of an analog self-interference signal with respect to the signal and then storing same; and receiving from the counterpart node an ACK/NACK signal with respect to the transmission of the signal; and determining whether or not the stored residual self-interference signal is to be used thereafter on the basis of the ACK/NACK signal.
