The exam- ple method may receive, from an gNB, a radio resource control (RRC) configuration indicating a UE-specific resource set that 605 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 620 size of a payload for a UCI to be transmitted on the PUCCH. The Determine one or more acknowledgement/non-acknowledgement (ACK/NACK) resources from the UE-specific resource set for an tion. aspects may thus enable dynamic ACK/NACK resource alloca- upcoming physical uplink control channel (PUCCH) based, at least in part, on the ACK/NACK resource configuration 630 Transmit, from the UE, an ACK/NACK for a physical downlink shared channel (PDSCH) on at least one of the one or more ACK/NACK resources determined based at least in part on the ACK/NACK resource configuration FIG. 6 [Continued on next page] Receive, from an gNB, a radio resource control (RRC) configuration indicating a UE-specific resource set that is a subset of a gNB resource pool 117 ,6/10 Receive, from an gNB, a physical downlink control channel (PDCCH) including a corresponding ACK/NACK resource configuration WO 2018/169879 Al D ill MC, MK, MT, NL, NO, PL, PT, RO, RS, SE, SI, SK, SM, TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
