Methods and apparatuses for controlling preemption of uplink transmissions in a communication network

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. For example, the UE (12) ignores the preemption indicator if the UCI is of the certain type or priority, and otherwise follows the preemption indicator by skipping the uplink data transmission. Correspondingly, a radio network node (22) configured for operation in the wireless communication network (10) determines whether an uplink data transmission by a UE (12) on certain radio resources will include UCI, and the radio network node (22) transmits or does not transmit a preemption indicator preempting use by the UE (12) of the certain radio resources for the uplink data transmission, in dependence on the determination.
