A mobile station device comprising circuitry that is configured and/or programmed to derive channel quality information which includes at least one of a channel quality indicator, a rank indication, and a precoding matrix indicator and to transmit the channel quality information using a physical uplink channel resource between a first physical uplink channel resource and a second physical uplink channel resource. The physical uplink channel resource is given by comparing a first bandwidth for the first physical uplink channel resource and a second bandwidth for the second physical uplink channel resource. The first bandwidth and the second bandwidth are expressed as a number of resource blocks.
