Abstract
A method by which a first network node cancels a self-interference signal when operating in a full duplex radio (FDR) mode in a wireless network can comprise the steps of: cancelling a self-interference signal on the basis of frequency synchronization estimation of the self-interference signal when frequencies of a reception signal received from a second network node and the self-interference signal are asynchronous; and estimating frequency synchronization of the reception signal by using a residual signal according to the cancellation of the self-interference signal, and detecting the reception signal on the basis of the frequency synchronization estimation of the reception signal.
