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 being a signal to another user terminal; and a base station that manages the serving cell. The base station includes a base station-side control unit configured to superpose an interference replica signal corresponding to the interference wave signal on the desired wave signal so as to cancel the interference wave signal received by the user terminal. The base station-side control unit transmits a predetermined signal corresponding to a first reference signal included in the interference wave signal. The user terminal includes a terminal-side control unit configured to derive first received power under a situation where the interference replica signal is superposed on the desired wave signal on the basis of at least one of the first reference signal and the predetermined signal.
