Abstract
In a radio communication system that performs beamforming in MIMO transmission between a radio base station and at least one user terminal, radio base station (10) includes: weight control section (104) that determines a beamforming weight used for the beamforming, for each of subbands formed by dividing a transmission band; and communication section (109) that transmits a signal to which the beamforming is applied using the beamforming weight.
