METHOD AND DEVICE FOR REMOVING SELF-INTERFERENCE SIGNAL IN ENVIRONMENT USING FDR MODE

WIPO Patent Application WO/2016/117801

A1

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; receiving from the counterpart node a NACK signal with respect to the transmission of the signal; retransmitting the signal to the counterpart node; and, if decoding of the signal which has been received in the predetermined time interval is successful, using only a part of the stored residual self-interference signal when removing a digital self-interference signal on the basis of the retransmission.
