Abstract

Disclosed is a control apparatus capable of more effectively utilizing radio resources. Mobile stations positioned close to each other are treated as one group, and a direction and width (radiation angle) of a beam radiated from an adaptive array antenna 11 is controlled for each group so that one beam capture one group. To be concrete, a plurality of mobile stations are classified into groups by a classification section 19, and an area to which each group moves is estimated by a directivity determination section 20. The adaptive array antenna 11 is controlled by the directivity control section 15 so that one beam can cover an area in which one group is positioned and the area to which this one group moves.
