Method for reporting the results of specific reference-cell-based quality measurement in a mobile communication system using carrier aggregation, and apparatus for the method

摘要

The present invention relates to a method in which a terminal reports the results of quality measurement based on a specific reference cell from among a plurality of serving cells for the terminal in a mobile communication system using carrier aggregation. The present invention also relates to a terminal apparatus for the method. For this purpose, the terminal receives measurement configuration information from a network, performs a quality measurement in accordance with the received measurement configuration information, determines whether or not a report criterion based on a specific reference cell from among the plurality of cells for the terminal is met in accordance with the measurement result, and, if the report criterion based on the specific reference cell is met, sends a report message, including the measurement results and an indicator that indicates the specific reference cell, to the network.

1. A method of reporting a cell measurement by a user equipment (UE) in a mobile communication system, the method comprising:
transmitting a first measurement report for a first type serving cell according to a reporting criterion configured in the UE; configuring a second type serving cell in addition to the first type serving cell which is currently configured in the UE; reporting a second measurement report for at least one of a plurality of serving cells including a first type serving cell and a second type serving cell according to the reporting criterion, wherein the reporting criterion comprises a predetermined event which is applied to the first type serving cell only regardless of whether the second type serving cell has been configured in the UE, wherein the reporting the second measurement report comprises reporting a result of cell measurement to a base station, if the reporting criterion of the predetermined event has been configured and if the result of the cell measurement satisfies the reporting criterion of the predetermined event in which a neighbor cell measurement becomes offset better than a serving cell measurement which excludes the second type serving cell.
