Abstract

A method and apparatus of reporting a measurement result in a wireless communication system is provided. A user equipment receives, from a base station, measurement configuration information comprising a reporting condition for triggering reporting of a measurement result on M component carriers among N component carriers, where M≦N. The user equipment determines whether the reporting condition is satisfied by measuring the N component carriers. If the reporting condition is satisfied, the user equipment reports a measurement result on the M component carriers to the base station.

Claims

1. A method of reporting a measurement result in a wireless communication system, the method comprising:

receiving, from a base station, measurement configuration information comprising a reporting condition for triggering reporting of a measurement result on M component carriers among N component carriers,

wherein M≦

N;

determining whether the reporting condition is satisfied by measuring the N component carriers; and

reporting a measurement result on the M component carriers to the base station if the reporting condition is satisfied,

wherein the M component carriers comprise component carriers having best quality among the N component carriers, and

wherein the reporting condition is to trigger the reporting of the measurement result when an order of quality of newly selected M component carriers is different from an order of quality of previously reported M component carriers.

2. The method of claim 1, wherein whether the reporting condition is satisfied is determined periodically.

3. The method of claim 1, wherein the reporting condition is to trigger the reporting of the measurement result when the M component carriers are determined.

4. The method of claim 1, further comprising receiving a management message for activating or inactivating at least one of the N component carriers from the base station.

5. The method of claim 1, wherein the measurement result comprises an identifier for identifying the M component carriers.

6. The method of claim 5, wherein the measurement result further comprises a quality value of the M component carriers.

7. A user equipment for reporting a measurement result in a wireless communication system, the user equipment comprising:

a radio frequency (RF) unit configured to transmit and receive a radio signal; and

a processor operatively coupled to the RF unit and configured to implement a radio interface protocol, wherein the processor is further configured to;

receive, from a base station, measurement configuration information comprising a reporting condition for triggering reporting of a measurement result on M component carriers among N component carriers,

wherein M≦

N;

determine whether the reporting condition is satisfied by measuring the N component carriers; and

report a measurement result on the M component carriers to the base station if the reporting condition is satisfied,

wherein the M component carriers comprise component carriers having best quality among the N component carriers, and

wherein the reporting condition is to trigger the reporting of the measurement result when an order of quality of newly selected M component carriers is different from an order of quality of previously reported M component carriers.

8. The user equipment of claim 7, wherein the processor is configured to periodically determine whether the reporting condition is satisfied.
