<P>PROBLEM TO BE SOLVED: To provide a radio base station device which can efficiently improve communication quality. <P>SOLUTION: A radio base station device comprises: a plurality of radio units R1 and R2 which perform radio communication with radio terminals A, B and C; and a control unit G for controlling the radio units R1 and R2. Each of the radio units R1 and R2 comprises: a terminal radio wave state measuring unit 12 for measuring states of radio waves transmitted from the radio terminals A, B and C; and a radio wave information transmission unit 13 for transmitting measurement results by the terminal radio wave state measuring unit 12 as radio wave information to the control unit G. The control unit G comprises a cooperative AAS (Adaptive array Antenna System) application terminal determination unit 21 for, based on the radio wave information from the radio units R1 and R2, determining to which terminal among the radio terminals A, B and C to apply cooperative communication that performs communication by using a plurality of radio units in cooperation. <P>COPYRIGHT: (C)2013,JPO&INPIT |
