17. A method performed by a wireless transmit/receive unit (WTRU) and comprising:
receiving one or more configured grants, each of the one or more configured grants comprising an indication of periodic transmission resources, each periodic transmission resource comprising time and frequency resources for hybrid automatic repeat request (HARQ) process transmission;
sending a transmission in accordance with a first configured grant of the one or more configured grants, wherein the transmission is associated with one or more HARQ processes and control information, the control information comprising a HARQ process identifier (ID) and a redundancy version (RV) for each of the one or more HARQ processes, wherein a number of resources for the control information is based on an offset value;
receiving a downlink control information (DCI) using an ID of the WTRU, the DCI comprising a downlink feedback indicator and a bitmap, wherein each bit of the bitmap indicates feedback for a corresponding HARQ process of the one or more HARQ processes; and
retransmitting data associated with a first HARQ process of the one or more HARQ processes, upon determining a negative acknowledgement for the first HARQ process based on the downlink feedback indicator and the bitmap for a prior transmission of the data associated with the first HARQ process.
