TERMINAL DEVICE, BASE STATION DEVICE, COMMUNICATION METHOD, AND INTEGRATED CIRCUIT

摘要

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 channel state information (CSI) related to a plurality of CSI processes of a first serving cell, and CSI of a second serving cell. First CSI related to some of the plurality of CSI processes of the first serving cell is reported on a physical uplink control channel (PUCCH) using a first format. Second CSI related to the rest of the plurality of CSI processes of the first serving cell is reported on the PUCCH using the first format. In cases when the reporting of the second CSI and the reporting of the CSI of the second serving cell clash in a certain subframe, the second CSI and the CSI of the second serving cell are reported on the PUCCH using a second format.
