Abstract: The objective of the invention is to suppress, in a case of applying the RRH system in an environment having a plurality of cells (multi-cellular environment), the reduction of the throughput of the whole system. A base station, in the RRH system in which a plurality of antenna ports are dispersively placed in each of a plurality of cells, comprises: a selection unit that selects antenna ports, to which user terminals are to connect, from among the antenna ports of the cells in which the user terminals are existent; and a power setting unit that controls the transmission powers of the antenna ports. The selection unit and power setting unit set predetermined conditions for the target SINRs(t) of the user terminals and the transmission powers of the antenna ports, and select the antenna ports for the user terminals and control the transmission powers of the antenna ports such that the smallest one of the values of the SINRs of the user terminals of the plurality of cells is maximized.
