## Abstract

A terminal according to one aspect of the present disclosure includes a receiving section that receives a configuration of a transform precoder of an RRC parameter to which enabled or disabled is configured and a configuration of a maximum rank to which a specific value or a value smaller than the specific value is configured, when a physical uplink shared channel (PUSCH) waveform can be dynamically switched, and a control section that controls transmission of the PUSCH. According to one aspect of the present disclosure, it is possible to appropriately switch a waveform.

## Claims

### Claim 1

A terminal comprising:
a receiving section that receives a configuration of a transform precoder of an RRC parameter to which enabled or disabled is configured and a configuration of a maximum rank to which a specific value or a value smaller than the specific value is configured, when a physical uplink shared channel (PUSCH) waveform can be dynamically switched; and
a control section that controls transmission of the PUSCH.

### Claim 2 (depends on 1)

The terminal according to claim 1, wherein
the transform precoder is configured to enabled.

### Claim 3 (depends on 1)

The terminal according to claim 1, wherein
the transform precoder is configured to disabled.

### Claim 4 (depends on 1)

The terminal according to claim 1, wherein
the maximum rank is configured to 1.

### Claim 5

A radio communication method for a terminal, the radio communication method comprising:
receiving a configuration of a transform precoder of an RRC parameter to which enabled or disabled is configured and a configuration of a maximum rank to which a specific value or a value smaller than the specific value is configured, when a physical uplink shared channel (PUSCH) waveform can be dynamically switched; and
controlling transmission of the PUSCH.

### Claim 6

A base station comprising:
a transmitting section that transmits a configuration of a transform precoder of an RRC parameter to which enabled or disabled is configured and a configuration of a maximum rank to which a specific value or a value smaller than the specific value is configured, when a physical uplink shared channel (PUSCH) waveform can be dynamically switched; and
a control section that controls reception of the PUSCH.
