The purpose of the present invention is to efficiently report uplink channel state information. This terminal device is provided with a transmission unit which reports a first RI related to a first CSI process, and which reports a second RI related to a second CSI process. In cases when the reporting of the first RI and the reporting of the second RI clash in a certain subframe, the first RI and the second RI are reported on the same physical uplink control channel using a first format, and the first CSI process is not an RI reference CSI process of the second CSI process, the first RI and the second RI are reported. In cases when the first CSI process is the RI reference CSI process of the second CSI process, the reporting of the first RI or the reporting of the second RI is dropped. |
