1. A method for reporting a logged measurement in a wireless communication system, the method comprising:
- receiving, by a user equipment, a measurement configuration;
selecting, by the user equipment, a serving cell identifier, a neighboring cell identifier, and a neighboring cell measurement result, to be logged in each log entry of a measurement report based on the measurement configuration;
reporting, by the user equipment, the measurement report to a base station; and
comparing the neighboring cell measurement result to a predetermined threshold,wherein, when a serving cell of the user equipment is changed, the serving cell identifier is included in a corresponding log entry,wherein, at a first time when the neighboring cell measurement result is less than the predetermined threshold, both of the neighboring cell identifier and the neighboring cell measurement result are included in the corresponding log entry,wherein, at a second time when the neighboring cell measurement result is greater than the predetermined threshold, only the neighboring cell identifier except for the neighboring cell measurement result is included in the corresponding log entry, andwherein the predetermined threshold is determined based on a radio access technology of the neighboring cell.

Abstract
The present invention relates to a method and apparatus for performing a logged measurement in a wireless communication system. A terminal receives a measurement configuration and a terminal selection parameter from a base station. The terminal determines whether or not to apply the measurement configuration based on the terminal selection parameter. If the measurement configuration is determined to be applied, the terminal logs a measurement based on the measurement configuration.

9. A wireless device configured for reporting a logged measurement in a wireless communication system, the wireless device comprising:
-
a radio frequency unit configured to transmit and receive a radio signal; and a processor operably connected to the radio frequency unit and configured to; receive a measurement configuration; select, by the user equipment, a serving cell identifier, a neighboring cell identifier, and a neighboring cell measurement result, to be logged in each log entry of a measurement report based on the measurement configuration; report the measurement report to a base station; and compare the neighboring cell measurement result to a predetermined threshold, wherein, when a serving cell of the user equipment is changed, the serving cell identifier is included in a corresponding log entry, wherein, at a first time when the neighboring cell measurement result is less than the predetermined threshold, both of the neighboring cell identifier and the neighboring cell measurement result are included in the corresponding log entry, wherein, at a second time when the neighboring cell measurement result is greater than the predetermined threshold, only the neighboring cell identifier except for the neighboring cell measurement result is included in the corresponding log entry, and wherein the predetermined threshold is determined based on a radio access technology of the neighboring cell. - View Dependent Claims (10, 11)
