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 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 , and an area to which each group moves is estimated by a directivity determination section . The adaptive array antenna is controlled by the directivity control section so that one beam can cover an area in which one group is positioned and the area to which this one group moves.
