## Abstract

A user equipment (UE) is described. The UE includes receiving circuitry configured to receive resource allocation information of a mini-slot physical uplink shared channel (PUSCH) and a number of repetitions for the PUSCH. The UE also includes control circuitry configured to determine a redundancy version (RV) for the number of repetitions. The UE further includes transmission circuitry configured to transmit the number of repetitions for the PUSCH based on the determined RV.

## Claims

### Claim 1

A user equipment (UE) that communicates with a base station comprising:
receiving circuitry configured to:
receive a Radio Resource Control (RRC) message including first information indicating that more than one configured grant (CG) Physical Uplink Shared Channel (PUSCH) transmission configuration is configured for the UE,
receive a RRC message including second information indicating a first redundancy version (RV) sequence for a first CG PUSCH transmission, and
receive a RRC message including third information indicating a second RV sequence for a second CG PUSCH transmission, and
transmitting circuitry configured to:
perform repetitions of the first CG PUSCH transmission based on the first second information, wherein
a repetition (transmission occasion) of the first CG PUSCH transmission is split into multiple actual repetitions (transmission occasions) if the repetition (transmission occasion) goes across the slot boundary or downlink/uplink switching point, and
RV for each actual repetition (transmission occasion) of the first CG PUSCH transmission is determined by the first RV sequence, and
perform repetitions of the second CG PUSCH transmission based on the third information, wherein
a repetition (transmission occasion) of the second CG PUSCH transmission is split into multiple actual repetitions (transmission occasions) if the repetition (transmission occasion) goes across the slot boundary or downlink/uplink switching point, and
RV for each actual repetition (transmission occasion) of the second CG PUSCH transmission is determined by the second RV sequence.

### Claim 2

A base station apparatus that communicates with a user equipment (UE) comprising:
transmitting circuitry configured to:
transmit a Radio Resource Control (RRC) message including first information indicating that more than one configured grant (CG) Physical Uplink Shared Channel (PUSCH) transmission configuration is configured for the UE,
transmit a RRC message including second information indicating a first redundancy version (RV) sequence for a first CG PUSCH transmission, and
transmit a RRC message including third information indicating a second RV sequence for a second CG PUSCH transmission, and
receiving circuitry configured to:
receive repetitions of the first CG PUSCH transmission based on the second information, wherein
a repetition (transmission occasion) of the first CG PUSCH transmission is split into multiple actual repetitions (transmission occasions) if the repetition (transmission occasion) goes across the slot boundary or downlink/uplink switching point, and
RV for each actual repetition (transmission occasion) of the first CG PUSCH transmission is determined by the first RV sequence, and
receive repetitions of the second CG PUSCH transmission based on the third information, wherein
a repetition (transmission occasion) of the second CG PUSCH transmission is split into multiple actual repetitions (transmission occasions) if the repetition (transmission occasion) goes across the slot boundary or downlink/uplink switching point, and
RV for each actual repetition (transmission occasion) of the second CG PUSCH transmission is determined by the second RV sequence.

### Claim 3

A communication method of a user equipment (UE) comprising:
receiving a Radio Resource Control (RRC) message including first information indicating that more than one configured grant (CG) Physical Uplink Shared Channel (PUSCH) transmission configuration is configured for the UE,

receiving a RRC message including third information indicating a second RV sequence for a second CG PUSCH transmission,
transmitting repetitions of the first CG PUSCH transmission based on the second information, wherein
a repetition (transmission occasion) of the first CG PUSCH transmission is split into multiple actual repetitions (transmission occasions) if the repetition (transmission occasion) goes across the slot boundary or downlink/uplink switching point, and
RV for each actual repetition (transmission occasion) of the first CG PUSCH transmission is determined by the first RV sequence, and
transmitting repetitions of the second CG PUSCH transmission based on the third information, wherein
