Terminal apparatus, base station apparatus, and communication method

A base station device comprising:

• transmission circuitry configured to transmit a physical downlink shared channel (PDSCH);
• and
• reception circuitry configured to receive a physical uplink control channel (PUCCH) resource,
• wherein, a first channel state information (CSI) with a hybrid auto repeat request-acknowledgment (HARQ-ACK), for the PDSCH are multiplexed if multi-CSI-PUCCH-ResourceList is not configured, and a second CSI with the first CSI and the HARQ-ACK are not multiplexed, in a case that at least one OFDM symbol of multiple OFDM symbols to which a first PUCCH for the first CSI is mapped is same as one OFDM symbol of multiple OFDM symbols to which a third PUCCH for the HARQ-ACK is mapped, and at least one OFDM symbol of multiple OFDM symbols to which a second PUCCH for the second CSI is mapped is same as one OFDM symbol of multiple OFDM symbols to which the third PUCCH is mapped,
• wherein the first CSI being with higher priority than the second CSI,
• each OFDM symbol of multiple OFDM symbols to which the first PUCCH for the first CSI is mapped is different from any OFDM symbol of multiple OFDM symbols to which the second PUCCH for the second CSI is mapped, and
• the reception circuitry is configured to receive the PUCCH resource, if the multi-CSI-PUCCH-ResourceList is configured, the second CSI with the first CSI and the HARQ-ACK are multiplexed.

A communication method using a terminal device, the communication method comprising:

• receiving a physical downlink shared channel (PDSCH);
• and
• multiplexing, if multi-CSI-PUCCH-ResourceList is not configured, a first channel state information (CSI) with a hybrid auto repeat request-acknowledgement (HARQ-ACK) for the PDSCH and not to multiplexing a second CSI with the first CSI and the HARQ-ACK in a case that at least one OFDM symbol of multiple OFDM symbols to which a first physical uplink control channel (PUCCH) for the first CSI is mapped is same as one OFDM symbol of multiple OFDM symbols to which a third PUCCH for the HARQ-ACK is mapped, and at least one OFDM symbol of multiple OFDM symbols to which a second PUCCH for the second CSI is mapped is same as one OFDM symbol of multiple OFDM symbols to which the third PUCCH is mapped,
• wherein the first CSI being with higher priority than the second CSI,
• each OFDM symbol of multiple OFDM symbols to which the first PUCCH for the first CSI is mapped is different from any OFDM symbol of multiple OFDM symbols to which the second PUCCH for the second CSI is mapped, and
• multiplexing, if the multi-CSI-PUCCH-ResourceList is configured, the second CSI with the first CSI and the HARQ-ACC.

A communication method using a base station device, the communication method comprising:

• wherein the first CSI being with higher priority than the second CSI,
• each OFDM symbol of multiple OFDM symbols to which the first PUCCH for the first CSI is mapped is different from any OFDM symbol of multiple OFDM symbols to which the second PUCCH for the second CSI is mapped, and
• receiving the PUCCH resource, if the mufti-CSI-PUCCH-ResourceList is configured, the second CSI with the first CSI and the HARQ-ACK are multiplexed.
