Conditional handover (cho) deconfiguration and failure handling in wireless communications

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a source base station, a conditional handover configuration that indicates one or more conditional handover configurations associated with one or more target base stations, wherein each of the one or more conditional handover configurations include a triggering measurement threshold for initiating a conditional handover to an associated target base station and a deconfiguration measurement threshold for deconfiguring the conditional handover configuration of the associated target base station;
• determine, based at least in part on the conditional handover configuration, that a first deconfiguration measurement threshold for deconfiguring a first conditional handover configuration of a first target base station is satisfied;
• and
• release the first conditional handover configuration of the first target base station.

An apparatus for wireless communication at a source base station, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• establish, 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 the respective target base station, wherein each conditional handover configuration includes a triggering measurement threshold for initiating the conditional handover of the UE to an associated target base station, a conditional handover timer value for completing the conditional handover of the UE to the associated target base station, and a deconfiguration measurement threshold for deconfiguring the conditional handover configuration of the associated target base station;
• and
• transmit, 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, the conditional handover timer value for completing the conditional handover of the UE to the associated target base station, and the deconfiguration measurement threshold for deconfiguring the conditional handover configuration of the associated target base station.
