<p>The purpose of the present invention is to enable the adequate reception of control information transmitted via a PDCCH in a predetermined frequency bandwidth, even if the bandwidth of a carrier which can execute CA in the predetermined frequency bandwidth has expanded. A mobile station (UE) according to the present invention is equipped with a reception unit (13) which is configured so as to receive control information, which is transmitted via a PDCCH, in the entire bandwidth of a carrier in a first frequency bandwidth and a carrier in a second frequency bandwidth, when a combination of the first frequency bandwidth and the second frequency bandwidth have been specified as a frequency bandwidth combination in which CA can be executed, and a carrier bandwidth combination in a plurality of frequency bandwidths has been specified, and the mobile station (UE) is compatible with at least one carrier bandwidth combination in the plurality of frequency bandwidths.</p> |
