An apparatus of a user equipment (UE) comprises one or more baseband processors to process payload size comprising a number of feedback bits for a hybrid automatic repeat request-acknowledgement (HARQ-ACK) configuration received from a New Radio (NR) NodeB (gNB) for physical uplink shared channel (PUSCH) transmission without grant, and to determine a size of reserved resource elements (REs) and mapping pattern in accordance with the configured HARQ-ACK payload size, and to transmit uplink shared channel on PUSCH without grant which is rate-matched around the reserved REs. The UE alternatively comprises one or more baseband processors to process a downlink control information (DCI) grant received from a to schedule a PUSCH transmission, wherein the one or more baseband processors are configured for dynamic DCI grant overwriting to process a dynamic indication to interrupt the scheduled PUSCH transmission.
