Base station apparatus, terminal apparatus, communication method, and integrated circuit

A base station device comprising:

• higher layer processing circuitry configured to transmit, by using radio resource control signaling, a first configuration for an aperiodic channel state information (CSI) report, the first configuration including a first information indicating that a transmission method for the aperiodic CSI report is aperiodic, a second configuration for a semi-persistent CSI report, the second configuration including a second information indicating that a transmission method for the semi-persistent CSI report is semi-persistent, a third configuration for an aperiodic CSI reference signal (CSI-RS), the third configuration including a third information indicating that a transmission method for the aperiodic CSI-RS is aperiodic, a fourth configuration for a semi-persistent CSI-RS, the fourth configuration including a fourth information indicating that a transmission method for the semi-persistent CSI-RS is semi-persistent, a fifth configuration for a periodic CSI report, the fifth configuration including a fifth information indicating that a transmission method for the periodic CSI report is periodic, and a sixth configuration for a periodic CSI-RS, the sixth configuration including a sixth information indicating that a transmission method for the periodic CSI-RS is periodic, the third information being different from the first information, the fourth information being different from the second information, the sixth information being different from the fifth information;
• and
• reception circuitry configured to, in a case that the semi-persistent CSI report with measurement of the semi-persistent CSI-RS and the aperiodic CSI report with measurement of the semi-persistent CSI-RS occur in a same time duration on a cell, receive the aperiodic CSI report, without receiving the semi-persistent CSI report, on a physical uplink shared channel (PUSCH) in the same time duration on the cell,
• wherein the semi-persistent CSI report is triggered by first downlink control information (DCI) included in a first physical downlink control channel (PDCCH), and
• the aperiodic CSI report is triggered by second DCI included in a second PDCCH.
