1. A method, performed by a wireless device, for modifying uplink, UL, data transmission with repetition in response to receiving a preemption indication, the method comprising:
beginning a UL data transmission comprising a plurality of repetitions of a data transmission, wherein at least two (2) repetitions are associated with different Redundancy Version, RV, values;
receiving a first preemption indication during a first repetition of the plurality of repetitions, wherein the first repetition is associated with a RV value of X, and X is a positive integer;
based on the first preemption indication, preempting the transmission of the first repetition to free up at least one resource;
after preempting the transmission of the first repetition and when the at least one resource is available again, retransmitting the first repetition of the UL data transmission that was preempted as a second repetition of the UL data transmission, wherein transmission of the second repetition reuses the RV value of X;
receiving a second preemption indication during transmission of the second repetition of the plurality of repetitions;
determining that the first repetition of the UL data transmission and the second repetition of the UL data transmission do not exceed a predefined percentage of a repetition associated with the RV; and
responsive to the determining, retransmitting the UL data transmission reusing the RV value of X.
