Classification: CPC H | IPC H

Claim 0:
1. A mobile station device comprising:
reception circuitry configured to and/or programmed to receive, from a base station device, first information via radio resource control (RRC) signaling on a physical downlink shared channel (PDSCH) using a first downlink carrier and second information on a physical downlink control channel (PDCCH); and
processing circuitry configured and/or programmed to, in a case that the first information is received, communicate with the base station device by aggregate use of the first downlink carrier and a second downlink carrier, wherein
the first information indicates a quantity of physical resource blocks (PRBs) of downlink effective bandwidth of the second downlink carrier to change from non-aggregate use of the first downlink carrier to aggregate use of the first downlink carrier and the second downlink carrier,
the second information indicates allocation of one or more physical resource blocks (PRBs) within the second downlink carrier,
each of the first downlink carrier and the second downlink carrier has its own downlink effective bandwidth, and
the downlink effective bandwidth being system bandwidth excluding guard bands.
