1. A method of operating a user equipment (UE) in a radio access network (RAN), the method comprising:
receiving, from a radio node in the RAN, a hybrid ARQ (HARQ) rescheduling indication that indicates rescheduling by the radio node of acknowledgement signaling previously scheduled for transmission by the UE, wherein the acknowledgement signaling is associated with one or more first downlink (DL) HARQ processes;
based on the HARQ rescheduling indication, determining a HARQ codebook to be used for encoding the rescheduled acknowledgement signaling together with further acknowledgement signaling associated with one or more second DL HARQ processes;
encoding the rescheduled acknowledgement signaling together with the further acknowledgement signaling based on the determined HARQ codebook; and
transmitting the encoded rescheduled acknowledgement signaling and further acknowledgement signaling to the radio node.
