ABSTRACT:
A base station apparatus includes a measurement unit, a derivation unit and an allocation unit. A base station apparatus allocates at least one subcarrier block, in a frequency band containing a plurality of subcarrier blocks composed of a plurality of subcarriers, to a terminal apparatus. The measurement unit measures an interference power of at least part of subcarriers among a plurality of subcarriers in each of the plurality of subcarrier blocks. The derivation unit derives, from the interference power of subcarriers measured by the measurement unit, an average value of the interference power for each of the plurality of subcarrier blocks and a statistical value indicating a degree of variation in the interference power relative to the average value. The allocation unit allocates at least one subcarrier block to the terminal apparatus, based on the average value and the statistical value derived by the derivation unit.
