摘要
A mobile communication system comprises: a user terminal that receives a desired wave signal from a serving cell while receiving an interference wave signal from a neighboring cell adjacent to the serving cell; and a base station that manages the serving cell. The base station comprises: a controller that generates an interference replica signal corresponding to the interference wave signal and superposes the interference replica signal on the desired wave signal; and a transmitter that transmits the desired wave signal superposed with the interference replica signal to the user terminal The controller generates the interference replica signal such that the interference replica signal cancels the interference wave signal in a location of the user terminal. The interference replica signal acts as a disturbing signal, which disturbs demodulation of the desired wave signal, in a location other than the location of the user terminal.
