Terminal device, base station device, integrated circuit and communication method

A base station device that communicates with a terminal device, the base station device comprising:

• transmitting circuitry configured to transmit higher layer information used to indicate two subframes sets for a single downlink component carrier;
• and
• receiving circuitry configured to receive:
• i) first channel state information for a pair of a first channel state information process and one of the two subframe sets,
• ii) second channel state information for a pair of a second channel state information process and another one of the two subframe sets, and
• iii) third channel state information for a pair of the first channel state information process and the another one of the two subframe sets.

A communication method of a terminal device that communicates with a base station device, the communication method comprising:

• receiving higher layer information used to indicate two subframe sets for a single downlink component carrier;
• transmitting first channel state information for a pair of a first channel state information process and one of the two subframe sets;
• transmitting second channel state information for a pair of a second channel state information process and another one of the two subframe sets;
• and
• transmitting third channel state information for a air of the first channel state information process and the another one of the two subframe sets.
