1. A method performed by a wireless device, comprising:

  • receiving a first downlink control channel message that schedules a first downlink shared channel transmission;

    receiving a second downlink control channel message that schedules a second downlink shared channel transmission;

    determining an uplink control channel resource to use for transmitting uplink control information to a network node on an uplink control channel, wherein;

    the uplink control information comprises Hybrid Automatic Repeat Request, HARQ, feedback for both the first downlink shared channel transmission and the second downlink shared channel transmission; and

    whereindetermining the uplink control channel resource to use for transmitting the uplink control information comprises determining the uplink control channel resource based on (a) signaling received from the network node and (b) resource determination performed by the wireless device based on a latest received one of the first downlink control channel message and the second downlink control channel message; and

    transmitting the uplink control information using the determined uplink control channel resource;

    wherein the signaling received from the network node comprises information that provides a semi-static configuration of two or more uplink control channel resource sets each comprising two or more uplink control channel resources; and

    wherein determining the uplink control channel resource based on (a) and (b) comprises selecting one of the two or more uplink control channel resource sets, and selecting, as the uplink control channel resource to use for transmitting the uplink control information to the network node, one of the two or more uplink control channel resources from the selected uplink control channel resource set based on dynamic signaling from the network node.
