## Abstract

A terminal apparatus includes a receiver configured to receive a physical downlink shared channel and a transmitter configured to multiplex first channel state information having a higher priority than second channel state information with the second channel state information and an HARQ-ACK and to transmit the first channel state information, the second channel state information and the HARQ-ACK multiplexed, by using a physical uplink control channel resource.

## Claims

### Claim 1

A terminal device comprising:
reception circuitry configured to receive a physical downlink shared channel (PDSCH); and
transmission circuitry configured to multiplex, 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 multiplex 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
the transmission circuitry configured to multiplex, if the multi-PUCCH-ResourceList is configured, the second CSI with the first CSI and the HARQ-ACK.

### Claim 2

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.

### Claim 3

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.

### Claim 4

A communication method using a base station device, the communication method comprising:
transmitting a physical downlink shared channel (PDSCH); and
receiving a physical uplink control channel (PUCCH) resource,
wherein, a first channel state information (CSI) with a hybrid auto repeat request-acknowledgement (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,
