1. A method for wireless communication at a source base station, comprising:
establishing, by the source base station, one or more conditional handover configurations with one or more target base stations for a conditional handover of a user equipment (UE) from the source base station to a respective target base station of the one or more target base stations, wherein each conditional handover configuration includes a triggering measurement threshold for initiating the conditional handover of the UE to an associated target base station and a conditional handover timer value for completing the conditional handover of the UE to the associated target base station;
transmitting, to the UE, the one or more conditional handover configurations that each indicate the associated target base station and the triggering measurement threshold for initiating the conditional handover to the associated target base station and the conditional handover timer value for completing the conditional handover of the UE to the associated target base station;
determining to deconfigure at least a first conditional handover configuration at the UE, wherein the determining is performed at the source base station or based at least in part on a signal from the associated target base station;
transmitting, responsive to the determining to deconfigure, deconfiguration information to the UE that indicates the UE is to delete one or more of a radio resource control configuration or a first measurement and reporting configuration for the first conditional handover configuration; and
releasing the first conditional handover configuration of a first target base station.
