MOBILE COMMUNICATION SYSTEM, COMMUNICATION CONTROL METHOD, BASE STATION, USER TERMINAL, AND PROCESSOR

摘要

A mobile communication system comprises: a user terminal that receives a desired wave signal from a serving cell and an interference wave signal that is a signal to another user terminal; and a first base station that manages the serving cell. The first base station includes: a control unit configured to generate configured to an interference replica signal corresponding to the interference wave signal and to superpose the interference replica signal on the desired wave signal; and a transmission unit configured to transmit the desired wave signal superposed with the interference replica signal to the user terminal. The control unit generates the interference replica signal such that the interference replica signal received by the user terminal cancels the interference wave signal received by the user terminal.
