In an aspect, the UE receives a downlink communication from a base station, the downlink communication including an update to at least one semi-persistent scheduling (SPS) or configured grant (CG) parameter. The downlink communication also indicates whether to use a first action time or a second action time for the update to take effect. The UE determines the action time for the at least one SPS or CG parameter update to take effect based on the downlink communication. The UE then applies the update to the at least one SPS or CG parameter for communications of the UE beginning at and following the action time. ## Claims ### Claim 1 A method of wireless communication for a user equipment (UE), comprising: receiving, by the UE, a downlink communication from a base station, the downlink communication including an update to at least one semi-persistent scheduling (SPS) or configured grant (CG) parameter, wherein the downlink communication indicates whether to use a first action time or a second action time for the update to take effect;
