Configurations for configured grant (CG) in new radio unlicensed (NR-U) systems is disclosed. CG configurations may, based on a periodicity, be provided either using a bitmap, shorter periodicity, or resource indicator value (RIV) signaling of start/end symbols, longer periodicity. Such CG configurations configure M sets of time division resource allocations. CG configuration may include common start/end symbols from for all contiguous allocations in one configuration. Common LBT starting points may be defined for all configured slots as indicated through a bitmap. The CG configuration allows for mini- and full slot configurations, in which the mini-slots are configured within the already configured CG slots. Repetition configurations include a type 1 for coverage and a type 2 for faster retransmission and reduced downlink feedback information (DFI) overhead. With multiple UEs, a UE identifier is added to the uplink control information (UCI). UEs may further ramp up power in the absence of DFI.
