In accordance with some exemplary embodiments, a UE may have multiple active CG configurations. These CG configurations may be in the same or different carriers/LBT sub-bands. A gNB can use DFI (e.g., DFI M shown in FIG. 1) or DCI to indicate the transmission parameter change for all or some of activated CG configurations. Similarly, the UE can use UCI to indicate the transmission parameter change for at least a part of the activated CG configurations. According to an embodiment, in the DFI/DCI/UCI, a bitmap may be defined to indicate which CG configuration(s) to apply the transmission parameter change as signaled by the DFI/DCI/UCI. In another embodiment, a CG configuration index may be carried by the DFI/DCI/UCI to indicate the corresponding CG configuration for which the transmission parameter change is to be applied. As yet another option, a HARQ process identifier (ID) may be signaled in the DFI/DCI/UCI to indicate which HARQ process needs to change transmission parameters. The indicated HARQ process may be associated with an activated CG configuration.
