<P>PROBLEM TO BE SOLVED: To reduce consumption power in a radio terminal and enable a proper adaptive array control. <P>SOLUTION: A radio base station eNB1, when receiving an uplink radio signal of a radio frequency band from a radio terminal UE2, calculates and stores a reception weight of each of adaptive array antenna 108A to adaptive array antenna 108D based on a reference signal for demodulation included in the uplink radio signal. Further, the radio base station eNB1 sets a reception weight which was calculated in the past and corresponding to which a frequency band is closest to a frequency band of a PDSCH as a setting target among the stored reception weights of the adaptive array antenna 108A to the adaptive array antenna 108D to a transmission weight of each of the adaptive array antenna 108A to the adaptive array antenna 108D. <P>COPYRIGHT: (C)2012,JPO&INPIT |
