Abstract:
A base station apparatus used for a FDD mobile communications system which uses at least a predetermined frequency bandwidth is disclosed. The base station apparatus includes a control unit which provides an instruction signal which at least indicates a frequency band used in wireless communications; and a unit which wirelessly communicates with a user apparatus according to the instruction signal, wherein, if the base station apparatus belongs to a predetermined border area between mobile communications systems, an instruction signal which indicates that use of one part of the predetermined frequency band is permitted, but use of another part is prohibited is provided by the control unit, and, if the base station apparatus belongs to a predetermined non-border area, an instruction signal which indicates that use of one part and use of the other part are permitted.
