Claim 12:
13. A method of operating a radio node in a radio access network (RAN), the method comprising:
upon failing to receive acknowledge signaling that was scheduled by the radio node for transmission by a user equipment (UE), transmitting to the UE a hybrid ARQ (HARQ) rescheduling indication that indicates rescheduling by the radio node of the acknowledgement signaling;
receiving, from the UE, the rescheduled acknowledgement signaling together with further acknowledgement signaling, wherein:
the rescheduled acknowledgement signaling includes HARQ feedback for one or more transmissions by the radio node associated with one or more first downlink (DL) HARQ processes, and
the further acknowledgement signaling includes HARQ feedback for one or more transmission by the radio node associated with one or more second DL HARQ processes;

based on the HARQ rescheduling indication, determining a HARQ codebook to be used for decoding the rescheduled acknowledgement signaling and the further acknowledgement signaling; and
based on the determined HARQ codebook, decoding the rescheduled acknowledgement signaling and the further acknowledgement signaling to obtain the HARQ feedback included therein.
