Abstract: A User Equipment (UE) (12) configured for operation in a wireless communication network (10) ignores a received preemption indicator responsive to determining that the involved data transmission by the UE (12) will carry Uplink Control Information (UCI) from the UE (12), at least when the UCI is of a certain type or priority.

Abstract: Modification of uplink (UL) data transmission with repetition in response to preemption indication is disclosed herein. In one embodiment, a wireless device modifies UL data transmission with repetition responsive to receiving a preemption indication. The wireless device begins 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.

The wireless device then retransmits the first repetition of the UL data transmission reusing the RV value of X. In some embodiments, after receiving the first preemption indication, the wireless device may cancel the UL data transmission if a code rate of the UL data transmission exceeds a threshold rate.
