WIRELESS STATION APPARATUS, WIRELESS COMMUNICATION SYSTEM, AND WIRELESS COMMUNICATION CONTROL METHOD

摘要

A wireless station apparatus is proposed that solves the problem of deterioration of communication quality. An arrival direction detection unit (13) detects the direction of arrival of uplink signals received by a wireless receiver (11). A mobile station determination unit (12) determines whether the transmission-origin mobile station of the uplink signals that are received by the wireless receiver (11) is a permitted mobile station or a nonpermitted mobile station. Based on the uplink signals received by the wireless receiver (11) and the determination result of the mobile station determination unit (12), an antenna adjustment unit (14) finds the degree of interference of permitted mobile stations and nonpermitted mobile stations in the direction of arrival that was detected in the arrival direction detection unit (13). The antenna adjustment unit (14) adjusts the direction of directivity of the reception antenna (10) in accordance with the degree of interference that was found.
