Method for transceiving signal in wireless communication system, and apparatus therefor
First Claim
1. A method of transceiving a signal in a wireless communication system, the method comprising:
- receiving a signal from a transmission antenna of a transceiver through a reception antenna of the transceiver during a dedicated time interval assigned for receiving the signal without an interference signal other than the received signal;
estimating a channel between the transmission antenna and the reception antenna based on the received signal;
generating a reference signal based on the estimated channel and a transmitting signal transmitted via the transmission antenna;
converting the reference signal into an analog signal;
receiving a data signal and a self-interference signal using the reception antenna; and
cancelling the self-interference signal from the received data signal using the analog signal.

Abstract
The present invention relates to a method for transceiving a signal in a wireless communication system. A method for transceiving a signal in a wireless communication system according to one embodiment of the present invention comprises the steps of: deducing a channel from a transmission antenna of a transceiver; generating a reference signal by combining the deduced channel and a transmission signal from the transmission antenna; converting the reference signal into an analog signal; receiving a data signal and a self-interference signal by means of a reception antenna of the transceiver; and canceling the self-interference signal from the received data signal by means of the converted reference signal, wherein deducing a channel and combining signals are performed in the digital domain and discarding the self-interference signal is performed in the analog domain.
