A base station A (101) comprises: baseband processing units (212a-212n) each of which successively acquires, updates and holds a terminal identification ID indicating the current connection status of a terminal for the respective one of other base station apparatuses (102a-102n) the cells of which are managed by the local apparatus together with the cell of the local apparatus itself; and an RRC layer processing/application unit (225a) that acquires, when a communication using a carrier aggregation is performed with the terminal, the terminal identifications ID of the carrier aggregation target cells from baseband processing units (212a, 212b) and determines a terminal identification ID that can be used between the carrier aggregation target cells. |
