Abstract: Embodiments of this application disclose an interference cancellation method and a base station. The method in the embodiments of this application may include obtaining, by a first base station, system information of a neighboring cell. The method may also include determining, by the first base station, interference channel information of a second base station to the first base station based on the system information, where the second base station is a base station in a coverage area of the neighboring cell. Furthermore, the method may also include receiving, by the first base station based on the interference channel information, an uplink signal sent by user equipment in a coverage area of the first base station.

Abstract: The present invention discloses a self-interference signal cancellation device. The device includes a first self-interference cancellation unit, configured to: obtain a first analog signal by coupling a transmit signal output by an analog transmit processing module; perform analog-to-digital conversion on the first analog signal, to obtain a first digital signal; perform interference reconstruction according to the first digital signal, to obtain a first digital interference cancellation signal; and cancel, according to the first digital interference cancellation signal, a self-interference signal included in a digital signal output by a first analog-to-digital conversion module, to obtain a first output signal, and output the first output signal to a digital receive processing module. In the present invention, after interference cancellation is performed by using the first digital interference cancellation signal and the digital signal output by the first analog-to-digital conversion module, a self-interference signal introduced during transmission can be canceled.
