## Abstract

To prevent deterioration of communication throughput and so on even when transmissions of uplink control information and one or more SRs overlap each other, a user terminal according to one aspect of the present disclosure includes: a transmitting section that transmits one or more scheduling requests; and a control section that controls transmission of the one or more scheduling requests, based on at least one of presence or absence of a configuration of a second PUCCH format, a number of configured PUCCH resource sets, and a number of scheduling request resource IDs corresponding to the one or more scheduling requests, when the one or more scheduling requests overlap uplink control information using a first PUCCH format.

## Claims

### Claim 1

A user terminal comprising:
a transmitting section that transmits one or more scheduling requests; and
a control section that controls transmission of the one or more scheduling requests, based on at least one of presence or absence of a configuration of a second PUCCH format, a number of configured PUCCH resource sets, and a number of scheduling request resource IDs corresponding to the one or more scheduling requests, when the one or more scheduling requests overlap uplink control information using a first PUCCH format.

### Claim 2 (depends on 1)

The user terminal according to claim 1, wherein
when the second PUCCH format is configured or when the number of the configured PUCCH resource sets is larger than one, the control section performs control so that the one or more scheduling requests and the uplink control information are transmitted by using the second PUCCH format.

### Claim 3 (depends on 1)

The user terminal according to claim 1, wherein
when the second PUCCH format is not configured or when the number of the configured PUCCH resource sets is one, the control section determines a resource to be used for transmission of the uplink control information, based on a type of the one or more scheduling requests.

### Claim 4 (depends on 1)

The user terminal according to claim 1, wherein
when the number of the scheduling request resource IDs corresponding to the one or more scheduling requests is one, the control section determines a resource to be used for transmission of the uplink control information, based on a type of the one or more scheduling requests.

### Claim 5 (depends on 1)

The user terminal according to claim 1, wherein
when the number of the scheduling request resource IDs corresponding to the one or more scheduling requests is larger than one, transmission of the one or more scheduling requests is controlled based on the presence or absence of the configuration of the second PUCCH format or the number of the configured PUCCH resource sets.

### Claim 6

A radio communication method for a user terminal, the radio communication method comprising:
transmitting one or more scheduling requests; and
controlling transmission of the one or more scheduling requests, based on at least one of presence or absence of a configuration of a second PUCCH format, a number of configured PUCCH resource sets, and a number of scheduling request resource IDs corresponding to the one or more scheduling requests, when the one or more scheduling requests overlap uplink control information using a first PUCCH format.

### Claim 7 (depends on 2)

The user terminal according to claim 2, wherein
when the second PUCCH format is not configured or when the number of the configured PUCCH resource sets is one, the control section determines a resource to be used for transmission of the uplink control information, based on a type of the one or more scheduling requests.

### Claim 8 (depends on 4)

The user terminal according to claim 4, wherein
when the number of the scheduling request resource IDs corresponding to the one or more scheduling requests is larger than one, transmission of the one or more scheduling requests is controlled based on the presence or absence of the configuration of the second PUCCH format or the number of the configured PUCCH resource sets.
