Device and method for performing handover in consideration of battery efficiency in wireless communication system

A method performed by a base station in a wireless communication system, the method comprising:

• transmitting configuration information related to a measurement report to a terminal;
• receiving the measurement report generated by the terminal based on the configuration information;
• and
• controlling the terminal to perform a handover from the base station to a neighbor base station,
• wherein the configuration information includes a threshold of signal strength for triggering the measurement report, that is determined based on a probability distribution determined based on information observed by terminals performing a handover in the base station, and
• wherein the probability distribution is determined based on a reward value, the reward value being determined based on observed information including at least one of information related to whether quality of service of the terminal is maintained or information related to a change in a battery consumption rate.

A terminal in a wireless communication system, the terminal comprising:

• a transceiver;
• and
• a processor coupled with the transceiver,
• wherein the processor is configured to:
• receive configuration information related to a measurement report from a base station,
• transmit the measurement report to the base station based on the configuration information, and
• perform a handover from the base station to a neighbor base station, and
• wherein the configuration information includes a threshold of signal strength for triggering the measurement report, that is determined based on a probability distribution determined based on information observed by terminals performing a handover in the base station, and
• wherein the probability distribution is determined based on a reward value, the reward value being determined based on observed information including at least one of information related to whether quality of service of the terminal is maintained or information related to a change in a battery consumption rate.
