## Abstract

A user terminal according to one aspect of the present disclosure includes: a control section that determines transmit power in a transmission occasion in a period of uplink transmission over a plurality of slots, the transmission occasion being a period of a whole of the uplink transmission or a period of transmission in one slot in the uplink transmission; and a transmitting section that uses the transmit power in the transmission occasion.

## Claims

### Claim 1

A terminal comprising:
a receiver that receives information indicating a number of repetitions of a physical uplink shared channel (PUSCH) allocated across a plurality of slots;
a processor that determines transmission power in a plurality of transmission occasions for the PUSCH across the plurality of slots, and divides the PUSCH into two segments by a slot boundary, each of the plurality of transmission occasions being a transmission occasion for a repetition of the PUSCH; and
a transmitter that transmits, based on the information, the PUSCH by using the transmission power in the transmission occasions,
wherein the processor controls transmission power for each transmission occasion corresponding to each repetition of the PUSCH, which is divided into two segments by the slot boundary.

### Claim 2

A radio communication method for a terminal, comprising:
receiving information indicating a number of repetitions of a physical uplink shared channel (PUSCH) allocated across a plurality of slots;
determining transmission power in a plurality of transmission occasions for the PUSCH across the plurality of slots, and dividing the PUSCH into two segments by a slot boundary, each of the plurality of transmission occasions being a transmission occasion for a repetition of the PUSCH;
transmitting, based on the information, the PUSCH by using the transmission power in the transmission occasions; and
controlling transmission power for each transmission occasion corresponding to each repetition of the PUSCH, which is divided into two segments by the slot boundary.

### Claim 3

A system comprising a terminal and a base station, wherein the terminal comprises:
a receiver of the terminal that receives information indicating a number of repetitions of a physical uplink shared channel (PUSCH) allocated across a plurality of slots;
a processor that determines transmission power in a plurality of transmission occasions for the PUSCH across the plurality of slots, and divides the PUSCH into two segments by a slot boundary, each of the plurality of transmission occasions being a transmission occasion for a repetition of the PUSCH; and
a transmitter of the terminal that transmits, based on the information, the PUSCH by using the transmission power in the transmission occasions,
wherein the processor controls transmission power for each transmission occasion corresponding to each repetition of the PUSCH, which is divided into two segments by the slot boundary, and
the base station comprises:
a transmitter of the base station that transmits the information; and
a receiver of the base station that receives the PUSCH.
