1. A method implemented in a user equipment (UE) to transmit control information to a communication network, the method comprising:
receiving, via radio resource control (RRC) signaling, a configuration of uplink (UL) resources to be used for transmitting control information to the communication network;
receiving a downlink control information (DCI) message, the DCI message comprising an assignment of radio resources to be used for receiving a downlink (DL) transmission from a base station of the communication network,
wherein the DCI message further comprises an acknowledgement resource indication (ARI) value that indicates, together with an acknowledgement feedback mode of the communication network, which of the configured UL resources to be used for transmitting control information comprising hybrid automatic repeat request (HARQ) feedback associated with the DL transmission, and
wherein, for the ARI value received in the DCI message, the configured UL resources comprise a first UL resource set for use in a first acknowledgement feedback mode of the communication network and a second UL resource set for use in a second acknowledgement feedback mode of the communication network; and
transmitting the control information comprising the HARQ feedback associated with the DL transmission to the base station on at least a subset of the UL resources indicated by the ARI value together with a current acknowledgement feedback mode of the communication network,
wherein the second UL resource set comprises the UL resources of the first UL resource set and UL resources in addition to those of the first UL resource set.
