1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, logged minimization of drive test (MDT) configuration information including a logging duration and an event for triggering a logging of measurement information;
starting a timer with a timer value set to the logging duration;
while the timer is running, in case that the event for triggering the logging is configured to an out-of-service area (OOS) and the UE is in any cell selection state, initiating the logging of the measurement information, based on the logged MDT configuration information, wherein the measurement information is logged only one time in the logging duration which is greater than 0, and wherein the UE is in a radio resource control (RRC) inactive mode; and
transmitting, to the base station, information related to the measurement information.
