ABSTRACT:
A base station transmits information in a downlink signal that identifies whether the base station is an adaptive array base station. If a terminal capable of performing diversity reception determines that a terminal to be connected is an adaptive array base station, it stops to perform diversity reception and set an antenna used for an uplink signal transmission to be used for an immediately following reception among a plurality of antennas (11, 12). Thus, a reception effectively utilizing transmission directivity from the adaptive array base station is attained, and interference wave can be reduced. These process are executed with software by DSP (18).
