Abrégé

A communication system (1) including a user terminal (30) and a plurality of base stations (20) carries out CoMP (Coordinated Multi-Point) communication where a plurality of wireless signals are transmitted to the user terminal (30) through a plurality of cells including a serving cell and a reference coordinated cell. The plurality of wireless signals containing the same data. The communication system (1) selects the reference coordinated cell among the plurality of coordinated cells. The user terminal (30) obtains an adjusting parameter to adjust the serving-cell phase using the wireless signals received from the reference coordinated cell and the serving cell, and transmits control information including the obtained adjusting parameter. The serving base station controls execution of the CoMP communication such that the serving-cell phase is adjusted on the basis of the adjusting parameter included in the received control information.
