(54) Title: UPLINK ACK RESOURCE ALLOCATION IN NEW RADIO 1-1 O N GC 1-1 00 O 1-1 N C (57) : A method and apparatus for enabling an UE to selecting acknowledgement/non-acknowledgement (ACK/NACK) re- sources from a subset of a gNB resource pool. The example method may receive, from an gNB, a radio resource control (RRC) config- uration indicating a UE-specific resource set that is a subset of a gNB resource pool. The UE may determine one or more ACK/NACK resources from the UE-specific resource set for an upcoming physical uplink control channel (PUCCH). In some aspects, the UE may determine the one or more ACK/NACK resources based on receiving, from the gNB, a physical downlink control channel (PDCCH) including a corresponding ACK/NACK resource configuration. In other aspects, the RRC may contain multiple resource subsets and the UE may determine the one or more ACK/NACK resources based on determining a size of a payload for a UCI to be transmitted on the PUCCH. The aspects may thus enable dynamic ACK/NACK resource allocation.
