<P>PROBLEM TO BE SOLVED: To obtain a base station equipment in which good antenna directivity control can be carried out even during the establishment of synchronization with a mobile station device or immediately after the establishment of synchronization. <P>SOLUTION: A correlation value detecting means D1-DN detects a value related to correlation between a predetermined signal corresponding a preamble signal and a received signal for each antenna A1-AN, a position detecting means E1-EN, 2 detects a position in the received signal where the predetermined signal is included based the detection results, an arriving angle detecting means 3 detects the arriving angle of the received signal based on the detection results of the correlation value at the detected position, a directivity control wireless communication means 5, F1-FN generates the weight of each antenna based on the detection results and multiplies a signal being communicated by each of the plurality of antennas by the weight of each antenna thus performing wireless communication while controlling the directivity of the plurality of antennas as whole. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
