Original Abstract Submitted
Embodiments include methods for a user equipment (UE) configured to operate in a radio access network (RAN). Such methods include receiving, from a radio node in the RAN, a new feedback indicator (NFI) that indicates whether acknowledgement signaling previously scheduled for transmission by the UE was received by the radio node. The acknowledgement signaling is associated with one or more first downlink (DL) hybrid ARQ (HARQ) processes. Such methods include, when the NFI indicates the acknowledgement signaling was not received by the RAN node, selecting a first HARQ codebook to be used for encoding the acknowledgement signaling together with further acknowledgement signaling associated with one or more second DL HARQ processes. Such methods include, using the selected first HARQ codebook, encoding the acknowledgement signaling and the further acknowledgement signaling to obtain first encoded information and transmitting the first encoded information to the radio node via an uplink (UL) channel.
