A radio base station (100) comprises a processor (120) for allocating, to a radio terminal, any of a plurality of frequency resources on the basis of channel information indicating a channel quality between the radio terminal and the radio base station (100). The processor (120) periodically acquires the respective pieces of channel information of the plurality of frequency resources, then averages the acquired pieces of channel information in the frequency direction and in the time direction to calculate average channel information, and then calculates, based on the channel information and the average channel information, an evaluation value to be used for deciding a frequency resource. In a particular time frame for which the calculation of evaluation value can be omitted, the processor (120) uses the channel information of some of the plurality of frequency resources to calculate average channel information or omit the calculation of average channel information. |
