Abstract:
A radio base station (eNB1), when having received an upstream radio signal of a radio frequency band from a radio terminal (UE2), calculates, based on a demodulation reference signal included in the upstream radio signal, and stores reception weights of antennas (108A to 108D). The radio base station (eNB1) further sets, as the transmission weight of each of the antennas (108A to 108D), that one of the stored reception weights of the antennas (108A to 108D) which was calculated during a past given interval and which corresponds to a frequency band that is the nearest to the frequency band of a PDSCH that is a target for setting.
