Abstract

There is provided a terminal device that communicates with a base station device. The terminal device includes a reception unit that receives downlink control information which is used for scheduling of a physical uplink shared channel and includes first information used to trigger a report of channel state information using the physical uplink shared channel, a higher layer signal including second information used to indicate two subframe sets, and the higher layer signal including third information. The third information is used to indicate a subframe set of the two subframe sets for which the report of the channel state information is triggered in a case that the report of the channel state information is triggered by a first value of a field of the first information, the third information is used to indicate a subframe set of the two subframe sets for which the report of the channel state information is triggered in a case that the report of the channel state information is triggered by a second value in the field of the first information, and the third information is used to indicate a subframe set of the two subframe sets for which the report of the channel state information is triggered in a case that the report of the channel state information is triggered by a third value in the field of the first information.
