## Abstract

In a terminal, in a slot having allocated thereto both an uplink control channel (PUCCH) and an uplink channel (PUSCH) that includes uplink data, in a case where the difference between the power spectrum density (PSD) of the PUCCH and the PSD of the PUSCH is greater than a threshold value (permitted difference), a control unit drops symbols of the PUSCH in a transmission interval for the PUSCH overlapping with a transmission interval for the PUCCH. A transmission unit transmits at least the PUCCH in the slot.

## Claims

### Claim 1

A terminal comprising:
a receiver, which, in operation, receives information associated with a mode where both an uplink control channel (PUCCH) and an uplink channel (PUSCH) are transmitted in a slot; and
circuitry, which, in operation, controls a transmission of the PUCCH and the PUSCH in the slot based on a difference between a power spectrum density (PSD) of the PUCCH and a PSD of the PUSCH,
wherein, in a case where a transmission interval for the PUCCH and a portion of a transmission interval for the PUSCH are superposed, the circuitry, in operation, sets a transient period in an interval that does not overlap with the transmission interval for the PUCCH, within the transmission interval for the PUSCH.

### Claim 2 (depends on 1)

The terminal according to claim 1, wherein in a case where the difference is greater than a threshold value, the circuitry, in operation, drops a symbol of the PUSCH in a transmission interval for the PUSCH overlapping with a transmission interval for the PUCCH.

### Claim 3 (depends on 1)

The terminal according to claim 1, wherein in a case where the difference is greater than a threshold value, the circuitry, in operation, drops a portion of resources of frequency resources to which the PUSCH is allocated in a transmission interval for the PUSCH overlapping with a transmission interval for the PUCCH.

### Claim 4 (depends on 1)

The terminal according to claim 1, wherein in a case where the difference is greater than a threshold value, the circuitry, in operation, changes a transmission format of the PUCCH.

### Claim 5 (depends on 3)

The terminal according to claim 3, wherein a unit for a frequency resource quantity at which the PUSCH is dropped is defined, and a transport block or a code block included in the PUSCH is mapped to frequency resources in the unit.

### Claim 6 (depends on 4)

The terminal according to claim 4, wherein, in a case where the transmission format has been changed from a short PUCCH to a long PUCCH, the circuitry, in operation, carries out power scaling for the long PUCCH.

### Claim 7

A communication method comprising:
receiving information associated with a mode where both an uplink control channel (PUCCH) and an uplink channel (PUSCH) are transmitted in a slot; and
controlling a transmission of the PUCCH and the PUSCH in the slot based on a difference between a power spectrum density (PSD) of the PUCCH and a PSD of the PUSCH,

A terminal comprising:
a receiver, which, in operation, receives information associated with a mode where both an uplink control channel (PUCCH) and an uplink channel (PUSCH) are transmitted in a slot; and
circuitry, which, in operation,
controls a transmission of the PUCCH and the PUSCH in the slot based on a difference between a power spectrum density (PSD) of the PUCCH and a PSD of the PUSCH,
