Method, apparatus, and system for measuring aggregated carrier cell

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.

What is claimed is: 
     
         1 . A method for measuring an aggregated carrier cell, comprising:
 receiving, by a user equipment, measurement configuration information of an aggregated carrier cell from a serving base station, wherein the measurement configuration information comprises signal estimation value information and a corresponding measurement period thereof;   obtaining, by the user equipment, a measurement period of the non-active component carrier according to a signal estimation value of a non-active component carrier in the aggregated carrier cell and the measurement configuration information; and   measuring, by the user equipment, the non-active component carrier according to the measurement period of the non-active component carrier.   
     
     
         2 . The method according to  claim 1 , wherein the signal estimation value information and the corresponding measurement period thereof in the measurement configuration information comprise a signal estimation value range and a corresponding measurement period thereof. 
     
     
         3 . A user equipment, comprising:
 a first obtaining unit, configured to receive measurement configuration information of an aggregated carrier cell from a serving base station, wherein the measurement configuration information comprises signal estimation value information and a corresponding measurement period thereof;   a second obtaining unit, configured to obtain 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   a measuring unit, configured to measure the non-active component carrier according to the measurement period of the non-active component carrier.   
     
     
         4 . The user equipment according to  claim 3 , wherein the signal estimation value information and the corresponding measurement period thereof in the measurement configuration information obtained by the first obtaining unit comprise a signal estimation value range and a corresponding measurement period thereof. 
     
     
         5 . A base station, comprising:
 a processer, configured to configure measurement configuration information of an aggregated carrier cell, wherein the measurement configuration information comprises signal estimation value information and a corresponding measurement period thereof; and   a transmitter, configured to send the measurement configuration information of the aggregated carrier cell to a user equipment;   wherein the measurement configuration information of the aggregated carrier cell is used by the user equipment to obtain a measurement period of a non-active component carrier and measure the non-active component carrier according to the measurement period of the non-active component carrier.   
     
     
         6 . The base station according to  claim 5 , wherein the signal estimation value information and the corresponding measurement period thereof in the measurement configuration information comprise a signal estimation value range and a corresponding measurement period thereof. 
     
     
         7 . A system for measuring an aggregated carrier cell, comprising a base station and the user equipment according to  claim 3 . 
     
     
         8 . The system according to  claim 7 , wherein the signal estimation value information and the corresponding measurement period thereof in the measurement configuration information obtained by the first obtaining unit comprise a signal estimation value range and a corresponding measurement period thereof. 
     
     
         9 . The system according to  claim 7 , wherein the base station, comprises:
 a processer, configured to configure measurement configuration information of an aggregated carrier cell, wherein the measurement configuration information comprises signal estimation value information and a corresponding measurement period thereof; and   a transmitter, configured to send the measurement configuration information of the aggregated carrier cell to a user equipment.
