Technology for a Next Generation NodeB (gNB) operable to encode a physical uplink control channel (PUCCH) resource indicator field length for transmission to a user equipment (UE) for enhanced Ultra Reliable Low Latency Communications (URLLC) (eURLLC) is disclosed. The gNB can determine the PUCCH resource indicator field length that indicates a length of a PUCCH resource indicator field, wherein the PUCCH resource indicator field length is related to transmission of a number of PUCCH symbols for eURLLC. The gNB can encode the PUCCH resource indicator field length for transmission in down-link control information (DCI) to the UE.
