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.

Abstract
Provided are a method and apparatus for performing logged measurement in a wireless communication system. A terminal receives measurement setup and a terminal selection parameter from a base station. The terminal determines whether to apply the measurement setup on the basis of the terminal selection parameter. If it is determined that the measurement setup is to be applied, the terminal performs measurement logging on the basis of the measurement setup.

3. An apparatus for performing logged measurement in a wireless communication system, the apparatus comprising:
-
a Radio Frequency (RF) unit that transmits and receives radio signals; and a processor connected to the RF unit, wherein the processor is configured to; receive a measurement configuration from a Base Station (BS), wherein the measurement configuration is a Minimization of Driving Tests (MDT) configuration for MDT measurement; receive 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, and wherein the UE selection parameter comprises an identifier of a UE group to which the measurement configuration will be applied; determine 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; start a validity timer if it is determined to apply the measurement configuration; log 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, and wherein, when the validity timer expires, the logged measurement is maintained while the MDT configuration is discarded; enter into an RRC connected mode; and while in the RRC connected mode, send a logging indicator to the BS to indicate 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, and wherein 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. - View Dependent Claims (4)
