## Abstract

Provided is a user equipment that: receives resource allocation; determines N transmission occasions on the basis of the resource allocation, where N is an integer greater than 1; determines a redundancy version (RV) value for each of the N transmission occasions on the basis of an RV sequence of length M; and transmits uplink in at least one transmission occasion from among the N transmission occasions on the basis of the RV value for the at least one transmission occasion. An RV value for an n-th transmission occasion from among the N transmission occasions is n mod M=K-th RV value, from among values in the RV sequence, where n=1, . . . , N.

## Claims

### Claim 1

A method of performing an uplink transmission by a user equipment (UE) in a wireless communication system, the method comprising:
receiving a resource allocation related to a physical uplink shared channel (PUSCH);
determining N transmission occasions related to the PUSCH based on the resource allocation, N being an integer greater than 1;
determining redundancy versions (RVs) for the N transmission occasions based on an RV sequence; and
performing a repetition transmission of the PUSCH in at least one of the N transmission occasions based on an RV for a corresponding transmission occasion,
wherein an RV for an n-th transmission occasion among the N transmission occasions is RVk in the RV sequence {RV0, RV1, RV2, RV3}, where k=n mod 4 and n=0, . . . , N−1, and
wherein performing the repetition transmission of the PUSCH in the at least one of the N transmission occasions comprises:
detecting a downlink control information (DCI) format; and
omitting the repetition transmission of the PUSCH in a part of the N transmission occasions based on the DCI format.

### Claim 2 (depends on 1)

The method according to claim 1, further comprising:
receiving information indicating the RV sequence among a plurality of predetermined RV sequences.

### Claim 3 (depends on 1)

The method according to claim 1, wherein the resource allocation includes at least a time-domain resource allocation.

### Claim 4 (depends on 1)

The method according to claim 1, wherein each of the N transmission occasions includes at least one symbol available for the uplink transmission.

### Claim 5 (depends on 4)

The method according to claim 4, further comprising:
receiving a time division duplex (TDD) uplink-downlink configuration; and
determining symbols available for the uplink transmission based on the TDD uplink-downlink configuration.

### Claim 6 (depends on 5)

The method according to claim 5, wherein the N transmission occasions include at least two transmission occasions separated based on invalid symbols for the uplink transmission, and
wherein the invalid symbols are determined based on at least the TDD uplink-downlink configuration.

### Claim 7 (depends on 4)

The method according to claim 4, wherein the N transmission occasions include at least two transmission occasions separated by a slot boundary.

### Claim 8

at least one transceiver;
at least one processor; and
at least one computer memory operably coupled to the at least one processor and storing instructions which when executed, cause the at least one processor to perform operations comprising:
receiving a resource allocation related to a physical uplink shared channel (PUSCH);
determining N transmission occasions related to the PUSCH based on the resource allocation, N being an integer greater than 1;
determining redundancy versions (RVs) for the N transmission occasions based on an RV sequence; and
performing a repetition transmission of the PUSCH in at least one of the N transmission occasions based on an RV for a corresponding transmission occasion,

wherein performing the repetition transmission of the PUSCH in the at least one of the N transmission occasions comprises:
detecting a downlink control information (DCI) format; and
omitting the repetition transmission of the PUSCH in a part of the N transmission occasions based on the DCI format.

### Claim 9

A base station (BS) configured to perform an uplink reception in a wireless communication system, the BS comprising:
at least one processor; and
at least one computer memory operably coupled to the at least one processor and storing instructions which when executed, cause the at least one processor to perform operations comprising:
transmitting a resource allocation related to a physical uplink shared channel (PUSCH);
determining N reception occasions related to the PUSCH based on the resource allocation, N being an integer greater than 1;
determining redundancy versions (RVs) for the N reception occasions based on an RV sequence; and
performing a repetition reception of the PUSCH in at least one of the N reception occasions based on an RV for a corresponding reception occasion, and
