Method and device for effectively performing standby mode operation in next generation mobile communication system

A method for receiving a measurement report of a base station, the method comprising:

• transmitting measurement configuration information to a terminal;
• and
• receiving a measurement report message generated based on the measurement configuration information,
• wherein in a case that a beam measurement result is determined to be included in the measurement report message, the measurement report message includes a cell-level measurement result and the beam measurement result of a serving cell.

A terminal for performing a measurement report, the terminal comprising:

• a transceiver;
• and
• a controller configured to perform control so as to receive measurement configuration information from a base station, perform measurement and determine whether or not report conditions are satisfied based on the measurement configuration information, generate a measurement report message in a case that the report conditions are satisfied, and transmit the measurement report message to the base station,
• wherein the controller is further configured to determine whether a beam measurement result is included in the measurement report message, and
• wherein in a case that the beam measurement result is determined in the measurement report message, the measurement report message includes a cell-level measurement result and a beam measurement result of a serving cell.

A base station for receiving a measurement report, the base station comprising:
