1. A serving cell, comprising:
a processor configured to generate a radio resource control (RRC) reconfiguration message including information indicating handover execution conditions and handover cancelation conditions for conditional handover (CHO) of service for a user equipment (UE) from the serving cell to a target cell, wherein:
a first of the handover execution conditions is based on whether a distance between the UE and a reference location is less than a threshold value,
a second of the handover execution conditions is based on whether a time elapsed from when the UE received the RRC reconfiguration message is greater than a threshold value, and
a first of the handover cancelation conditions is based on whether a distance between the UE and the reference location is greater than a threshold value; and
a transceiver operably coupled to the processor, the transceiver configured to:
transmit, to the UE, the RRC reconfiguration message, and
receive a handover completion acknowledgement based on completion of the CHO from the serving cell to the target cell.
