3 . The base station control system according to claim 1 , wherein upon occurrence of a condition in which the terminals include one or more third terminals that are not to be coupled to both the first base stations and the second base station, the circuitry is configured to

determine, for each of the transmitted power candidates regarding each possible combination of the first base stations, the number of third terminals, and

select a given transmitted power candidate of each first base station, from the transmitted power candidates regarding each combination pattern of the first base stations, based on the number of first terminals, the number of second terminals, and the number of third terminals.

4 . The base station control system according to claim 1 , wherein upon occurrence of a condition in which one transmitted power candidate of a given first base station is not selected, the circuitry is configured to select a given transmitted power candidate of the given first base station, based on (i) power to be received by one or more first terminals, the power being transmitted from the given first base station and (ii) power to be received by one or more second terminals, the power to be received by the second terminals being transmitted from the second base station, and

wherein the power to be received by the first base stations and the second base stations is specified for each transmitted power candidate.

candidate positions of each first base station, and

transmitted power candidates of the first base station that is at the candidate positions, based on positions of the one or more terminals;

determining, for each of the combination patterns regarding each possible combination of the first base stations, (i) the number of first terminals to be coupled to each of the first base stations and (ii) the number of second terminals to be coupled to the second base station, upon occurrence of a condition in which the first base stations are provided at the respective candidate positions, in conjunction with a condition in which each of the first base stations outputs transmitted power of the transmitted power candidates regarding the combination pattern; and

selecting one combination pattern from the combination patterns regarding possible combinations of the first base stations, based on the number of first terminals and the number of second terminals.
