1. A method of performing logged measurement in a wireless communication system, the method comprising:

  • receiving, by a user equipment (UE), a measurement configuration from a Base Station (BS),wherein the measurement configuration is a Minimization of Driving Tests (MDT) configuration for MDT measurement;

    receiving, by the UE, a UE selection parameter from the BS,wherein the measurement configuration is transmitted along with the UE selection parameter via a Radio Resource Control (RRC) message, andwherein the UE selection parameter comprises an identifier of a UE group to which the measurement configuration will be applied;

    determining, by the UE, whether or not to apply the measurement configuration by combining the UE selection parameter and a predefined parameter,wherein the predefined parameter includes at least one of negotiations with the BS regarding a UE'"'"'s participation in the measurement, a support of a Minimization of Driving Tests (MDT), or previously received information;

    starting a validity timer if it is determined to apply the measurement configuration;

    logging, by the UE, measurement based on the measurement configuration if it is determined to apply the measurement configuration,wherein the UE operates in Radio Resource Control (RRC) idle mode, andwherein, when the validity timer expires, the logged measurement is maintained while the MDT configuration is discarded;

    entering, by the UE, into an RRC connected mode; and

    while in the RRC connected mode, sending, by the UE to the BS, a logging indicator that indicates an availability of the logged measurement,wherein the logging indicator is included in at least a RRC connection setup complete message or a RRC connection reconfiguration complete message, andwherein the logging indicator is represented in a bitmap format having two bits such that the logging indicator further indicates an occasion of the logged measurement.
