Abstract
In a mobile communication system of the present invention, a base station apparatus and mobile station apparatus (user device) communicate each other on a plurality of downlink component carriers and a plurality of uplink component carriers. And while the mobile station apparatus (user device) transmit an uplink data to the base station apparatus on the plurality of uplink component carriers, the mobile station apparatus (user device) transmit a scheduling request for requesting uplink resource for the uplink data to the base station apparatus using a physical uplink control channel (PUCCH) only on a specific uplink component carrier of the plurality of uplink component carriers.
