Abstract
A terminal device configured to efficiently transmit uplink control information uses the first PUCCH resource and a first PUCCH format for transmission on a physical downlink shared channel (PDSCH) only in a first serving cell, and that uses, in accordance with the first information, either the second PUCCH resource and a second PUCCH format or the third PUCCH resource and a third PUCCH format for transmission on a PDSCH in a serving cell other than the first serving cell.

A terminal device comprising:
- receiving circuitry configured to receive a radio resource control signal including first information used for indicating for which serving cell(s) an aperiodic channel state information (CSI) report is triggered,
- the receiving circuitry configured to receive on a physical downlink control channel (PDCCH), downlink control information format 0 (DCI format 0) used for scheduling of a physical uplink shared channel (PUSCH);
- and
- transmitting circuity configured to perform, based on decoding of the DCI format 0, an aperiodic reporting using the PUSCH in a case that a channel state information (CSI) request field included in the DCI format is set to trigger an aperiodic report, wherein,
- in a case that 29 is indicated by using a modulation and coding scheme and redundancy version field included in the DCI format 0, only uplink control information is transmitted using the PUSCH if the CSI request field is 3 bits, the aperiodic CSI report is triggered for one serving cell based on the first information and a value of the 3-bit CSI request field, and a first predetermined number is indicated for allocated physical resource blocks,
- in the case that 29 is indicated by using the modulation and coding scheme and redundancy version field included in the DCI format 0, the only uplink control information is transmitted using the PUSCH if the CSI request field is 3 bits, the aperiodic CSI report is triggered for 2 to 5 serving cell, and a second predetermined number is indicated for the allocated physical resource blocks, and
- in the case that 29 is indicated by using the modulation and coding scheme and redundancy version field included in the DCI format 0, the only uplink control information is transmitted using the PUSCH if the CSI request field is 3 bits, the aperiodic CSI report is triggered for more than five serving cell.
