Abstract

An array antenna constituting section (22) constitutes one by one each array antenna by combining at least two transmitter / receivers (40). Each time one array antenna is constituted, an array antenna transmitting / receiving section (25) transmits a radio signal having a predetermined directivity pattern to a part or all of the antenna elements (42) not constituting the constituted array antenna. In response to the transmission from each array antenna, an array antenna communication performance measuring section (26) measures the reception level of each of a part or all of the antenna elements (42) and computes the array antenna communication performance value of each array antenna from the measured reception level. An array antenna determining section (23) determines a combination of at least two transmitter / receivers (40) constituting array antennas having a predetermined performance condition according to the array antenna communication performance value.

Description

technical field [0001] The present invention relates to an adaptive array base station device and its control method, in particular to an automatic transmission and reception device equipped with three or more transmission and reception control components including at least one antenna element and a transmission and reception control unit that controls the transmission and reception of wireless signals performed by the antenna element An adaptive array base station device and a control method thereof, and an adaptive array base station device and a control method thereof that selectively use at least three antenna elements to perform wireless communications with a plurality of mobile station devices respectively. Background technique [0002] The so-called adaptive array antenna (Adaptive Array Antenna) is composed of a plurality of antenna elements, by adaptively controlling the directivity (directivity) according to the radio wave propagation environment, thereby performing...
