Mobile station apparatus, the base station apparatus, a communication system, the mobile station apparatus capability notification method and the integrated circuit

摘要

An object of the invention is to provide a mobile station apparatus, a base station apparatus, a communication system, a mobile station apparatus capability notification method, and an integrated circuit, which enable uplink transmission timing support information of the mobile station apparatus to be effectively notified to the base station apparatus. The mobile station apparatus that is connected to the base station apparatus by aggregating a plurality of cells of which frequencies are different from each other transmits capability information in which information related to an uplink transmission timing supported by the mobile station apparatus is associated with the plurality of frequencies supported by the mobile station apparatus, to the base station apparatus.
