Abstract: Certain aspects of the present disclosure provide techniques for a user equipment (UE) to receive, via a first active cell serving the UE, a first control message activating a set of transmission configuration indicator states associated with a set of candidate cells that are inactive at the UE. The UE may receive, via the first active cell after receiving the first control message, a second control message indicating for the UE to switch to a second cell of the set of candidate cells. In response to receiving the second control message indicating for the UE to switch to the second cell, the UE may switch to communicating with the second cell using a first transmission configuration indicator state of the activated set of transmission configuration indicator states.
