1. A method of operating a User Equipment, UE, in a New Radio, NR, Radio Access Network, the method comprising:

  • transmitting Hybrid Automatic Repeat Request, HARQ, feedback pertaining to downlink data transmitted on a Physical Downlink Shared Channel, PDSCH, the downlink data comprising at least one downlink data element, the HARQ feedback having an uplink signaling format comprising at least one acknowledgement substructure, each of the substructures carrying acknowledgement information pertaining to a downlink data element, each of the acknowledgment substructures being mapped to a different of the downlink data elements based on at least one acknowledgement position indication provided in downlink control signaling received by the UE;

    the acknowledgment position indication comprising a timing indication, the timing indication comprising a timing bit pattern of more than one bit explicitly indicating a slot for transmitting the HARQ feedback, the slot comprising at least 14 symbol time intervals;

    the acknowledgement position indication further comprising a resource selection indication comprising a resource bit pattern, the resource bit pattern comprising more than one bit explicitly indicating a Physical Uplink Control Channel, PUCCH, resource for transmitting the HARQ feedback, the resource bit pattern being separate from the timing bit pattern; and

    the PUCCH resource being a time-frequency resource and being selected by the resource selection indication from a pool of resources configured to the UE to be available for transmitting the HARQ feedback in the slot indicated by the timing indication.
