A method and apparatus of reporting a logged measurement in a wireless communication system are provided. A user equipment receives a Minimization of Drive Tests (MDT) configuration and logs measurements based on the MDT configuration to collect a logged measurement. The user equipment receives an information request from a base station, to request the logged measurement, and transmits an information response to the base station that includes a part of the logged measurement and an availability indicator indicating that all entries in the logged measurement are not included in the information response. The availability indicator indicates a total size of the logged measurement to be received by the base station or an expected number of segments of the logged measurement to be received by the base station. The availability indicator further indicates a last segment of the logged measurement to be received by the base station.
