Method and apparatus for conditional handover operation in communication system

An operation method of a terminal in a communication system, the operation method comprising:

• performing a monitoring operation of a conditional handover (CHO) preparation event;
• transmitting a measurement report message to a base station when the CHO preparation event is detected;
• receiving, from the base station, an RRC reconfiguration message including CHO status report configuration information requesting transmission of information for determining a target cell to which the terminal is likely to be handed over among one or more candidate target cells;
• and
• transmitting a CHO status report message according to the CHO status report configuration information.

A terminal comprising:

• a processor;
• a memory electronically communicating with the processor;
• and
• instructions stored in the memory,
• wherein when executed by the processor, the instructions cause the terminal to:
• perform a monitoring operation of a conditional handover (CHO) preparation event;
• transmit a measurement report message to a base station when the CHO preparation event is detected;
• receive, from the base station, an RRC reconfiguration message including CHO status report configuration information requesting transmission of information for determining a target cell to which the terminal is likely to be handed over among one or more candidate target cells;
• and
• transmit a CHO status report message according to the CHO status report configuration information.
