ABSTRACT:
To reduce interference mutually provided among peripheral cells, and perform data transmission while maintaining total throughput at the maximum level.Provided are an acquiring section (105) that acquires information of interfering power level that a communication apparatus receives from peripheral cells from a signal received from the communication apparatus, a determining section (106) that determines the number of subcarriers to use in data transmission corresponding to the information of interfering power level, and a modulation scheme determining section (107) that determines a modulation scheme for each of the subcarriers to use in data transmission corresponding to the information of interfering power level, and a radio signal is transmitted to the communication apparatus using the modulation scheme determined in the modulation scheme determining section (107) and the number of subcarriers determined in the determining section (106).
