Abstract: A base station includes a measuring unit and a setting unit. The measuring unit configured to measure at least any one piece of information of an absolute value of received total wideband power in the cell, a dispersion value of the received total wideband power in the cell, a reception success rate which is a rate of success in packet reception in the cell, and a simultaneous connecting user number which is the number of radio terminals connected to the cell simultaneously. The setting unit configured to set target received total wideband power which is a target for the received total wideband power in the cell based on information measured by the measuring unit.

Abstract: Each of a plurality of frequencies defines a combination of at least one uplink from among a plurality of types of uplink radio access, and at least one downlink from among a plurality of types of downlink radio access. A base station (100a) includes an evaluation point calculation unit (150) which calculates the uplink evaluation points for each of the plurality of frequencies based on the uplink parameters contributing to the uplink throughput, and calculates the downlink evaluation points for each of the plurality of frequencies based on the downlink parameters contributing to the downlink throughput, and a selection unit (160) which selects the frequency to be used by the radio terminal of frequency selection target from among the plurality of frequencies, based on the uplink evaluation points and the downlink evaluation points.
