Zusammenfassung:The present disclosure relates to a method and apparatus for minimization of driving test (MDT) logging when an in-device coexistence (IDC) issue occurs in a wireless communication system. In accordance with one embodiment of the present disclosure, a method of operating a terminal in a wireless communication system may comprise the following steps of: receiving a logged measurement configuration message in a radio resource control (RRC) connection mode; receiving an RRC connection release message from a base station; logging measurement in an RRC_IDLE mode or an RRC_INACTIVE mode; based on the received logged measurement configuration message, logging the measurement such that an in-device coexistence (IDC) flag can be included when an IDC issue is detected during a last logging interval; and transmitting the logged measurement to the base station. 본 개시는 무선 통신 시스템에서 IDC(In-device coexistence) 문제 발생 시 MDT(Minimization of Driving Test) 로깅을 수행하는 방법 및 장치에 관한 것으로, 본 개시의 일 실시예에 따른 무선 통신 시스템에서 단말의 동작 방법 방법은, RRC(Radio Resource Control) 연결 모드(connected mode)에서 로그 측정 구성(LoggedMeasurementConfiguration) 메시지를 수신하는 단계; 기지국으로부터 RRC 연결 해제(RRC Release) 메시지를 수신하는 단계; RRC 유휴(RRC_IDLE) 모드 또는 RRC 비활성화(RRC_INACTIVE) 모드에서 측정을 로깅하는 단계; 상기 수신된 로그 측정 구성 메시지에 기초하여, 마지막 로깅 인터벌동안 IDC(In-Device Coexistence) 문제가 감지된 경우 IDC 플래그를 포함하도록 측정을 로깅하는 단계; 및 상기 로그된 측정을 기지국에게 전송하는 단계를 포함할 수 있다.
