<P>PROBLEM TO BE SOLVED: To provide a technology capable of enhancing accuracy of a reception weight. <P>SOLUTION: An estimation part 53 estimates the degree of a frequency selective fading in a transmission frequency band used by a communication partner device. A reception weight processing part 51, in the case where a radio resource allocation part 60 allocates a plurality of contiguous allocation unit bands to the communication partner device, calculates the reception weight based on a known signal included in a reception signal in the N allocation unit bands for each of N (≥1) allocation unit bands with respect to the plurality of contiguous allocation unit bands. The reception weight processing part 51 controls a reception directivity of a plurality of antennas in the corresponding N allocation unit bands based on the calculated reception weight. The reception weight processing part 51 determines a value of N based on the degree of the frequency selective fading estimated by the estimation part 53. <P>COPYRIGHT: (C)2012,JPO&INPIT |
