Abstract
The present invention enables random access which does not cause a load on a mobile station apparatus in an Advanced-EUTRA system. A wireless communication system in which a base station apparatus allocates a plurality of component carriers to a mobile station apparatus, and the base station apparatus and the mobile station apparatus perform communication via the component carriers, wherein the base station apparatus notifies the mobile station apparatus of allocation information of component carriers, setting information of a component carrier including information on random access, and setting information of a component carrier not including the information on random access; and the mobile station apparatus receives the allocation information and the setting information, and executes a random access procedure only in the component carrier in which the information on random access is included in the setting information of the component carrier, among the plurality of component carriers allocated from the base station apparatus.
