Abstract: The present disclosure provides a method and an apparatus for self-interference cancellation, a terminal and a base station are disclosed. The method includes truncating a signal based on a detection window, where the signal comprises a receive signal and a self-interference signal which is associated with a transmit signal, and a length of the detection window is less than a symbol length, performing self-interference channel estimation to obtain an estimation of a self-interference channel, based on the truncated signal and a first reference signal which is carried by the transmit signal and used for self-interference channel estimation, where the first reference signal has a comb structure in frequency domain, and performing self-interference cancellation based on the transmit signal and the estimation of the self-interference channel. The method can reduce the influence on the accuracy of self-interference channel estimation due to inter-symbol interference caused by timing misalignment.
