Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 17:
18. A radio node configured to operate in a radio access network (RAN), the radio node comprising:
radio circuitry configured to communicate with a user equipment (UE); and
processing circuitry operably coupled to the radio circuitry, whereby the processing circuitry and the radio circuitry are configured to:
upon failing to receive acknowledge signaling that was scheduled by the radio node for transmission by the UE, transmit to the UE a hybrid ARQ (HARQ) rescheduling indication that indicates rescheduling by the radio node of the acknowledgement signaling; and
receive, 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, determine a HARQ codebook to be used for decoding the rescheduled acknowledgement signaling and the further acknowledgement signaling; and
based on the determined HARQ codebook, decode the rescheduled acknowledgement signaling and the further acknowledgement signaling to obtain the HARQ feedback included therein.
