Embodiment Construction

[0023]The following describes embodiments of the present invention in detail with reference to the accompanying drawings.

[0024]An embodiment of the present invention provides a method for measuring an aggregated carrier cell. As shown in FIG. 1, the method includes the following steps:

[0025]101: A UE obtains measurement configuration information of an aggregated carrier cell, where the measurement configuration information includes signal estimation value information and a corresponding measurement period thereof.

[0026]102: The UE selects a measurement period of a non-active component carrier according to a signal estimation value of the non-active component carrier in the aggregated carrier cell and the measurement configuration information.

[0027]103: The UE measures the non-active component carrier according to the measurement period of the non-active component carrier.

[0028]By using the method for measuring an aggregated carrier cell provided in this embodiment, the UE measures d...

Abstract

A method for measuring an aggregated carrier cell includes the following content. A user equipment receives measurement configuration information of an aggregated carrier cell from a serving base station, where the measurement configuration information includes signal estimation value information and a corresponding measurement period thereof; the user equipment obtains a measurement period of a non-active component carrier according to a signal estimation value of the non-active component carrier in the aggregated carrier cell and the measurement configuration information; and the user equipment measures the non-active component carrier according to the measurement period. With the method of the present invention, the user equipment can measure different component carriers in an aggregated carrier cell in different periods.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 13 / 565,052, filed on Aug. 2, 2012, which is a continuation of International Application No. PCT / CN2011 / 070682, filed on Jan. 27, 2011, which claims priority to Chinese Patent Application No. 201010107381.5, filed on Feb. 3, 2010, both of which are hereby incorporated by reference in their entireties.FIELD OF THE INVENTION[0002]The present invention relates to the field of mobile communications, and in particular, to a technical solution of measuring an aggregated carrier cell.BACKGROUND OF THE INVENTION[0003]In a wireless cellular communication system, a user equipment (User Equipment, UE) in the active (Active) state determines a serving cell according to signal power of a cell, while a UE in the idle (Idle) state determines a camping cell according to the signal power of the cell. Therefore, the UE needs to measure signals of the serving cell or the camping cell and ...
