Abstract

The present application relates to a method in which a terminal transceives a signal in a wireless communication system. More particularly, the method comprises: a step of transmitting a measurement report on one or more neighboring base stations to a serving base station; a step of receiving a handover command message on a target base station from among said one or more neighboring base stations; and a step of performing handover to said target base station according to said handover command message. The handover command message includes an interference message received from said serving base station after performing said handover.

Claims

1. As a method of a user equipment for transceiving a signal in a wireless communication system, the method for transceiving a signal comprises:

transceiving a measurement report on one or more neighboring base stations to a serving base station;

receiving a handover command message respective to a target base station among the one or more neighboring base stations; and

performing handover to the target base station based upon the handover command message,

wherein the handover command message includes interference information that is to be received from the serving base station after performing the handover process.

2. The method of claim 1, wherein the interference information corresponds to information on a cell-specific reference signal of the serving base station.

3. The method of claim 2, wherein the information on a cell-specific reference signal corresponds to a maximum number of antenna ports for the cell-specific reference signal defined in the serving base station.

4. The method of claim 2, wherein the information on a cell-specific reference signal corresponds to a number of antenna ports used in downlink communication performed between the serving base station and the user equipment before the handover process.

5. The method of claim 1, further comprising:

applying an interference mitigating method based upon the interference information after performing the handover process.

6. The method of claim 1, further comprising:

transmitting the interference information to the target base station after performing the handover process.

7. The method of claim 1, wherein the interference information is delivered to the target base station from the serving base station.

8. The method of claim 1, wherein each of the serving base station and the target base station has a different cell identifier.

9. As a user equipment in a wireless communication system, the user equipment comprises:

a transmitting module configured to transceive a measurement report on one or more neighboring base stations to a serving base station;

a receiving module configured to receive a handover command message respective to a target base station among the one or more neighboring base stations; and

a processor configured to control the transmitting module and the receiving module, so that handover can be performed to the target base station based upon the handover command message,

wherein the handover command message includes interference information that is to be received from the serving base station after performing the handover process.

10. The user equipment of claim 9, wherein the interference information corresponds to information on a cell-specific reference signal of the serving base station.

11. The user equipment of claim 10, wherein the information on a cell-specific reference signal corresponds to a maximum number of antenna ports for the cell-specific reference signal defined in the serving base station.

12. The user equipment of claim 10, wherein the information on a cell-specific reference signal corresponds to a number of antenna ports used in downlink communication performed between the serving base station and the user equipment before the handover process.

13. The user equipment of claim 9, wherein the processor applies an interference mitigating method based upon the interference information after performing the handover process.

14. The user equipment of claim 9, wherein the transmitting module transmits the interference information to the target base station after performing the handover process.

15. The user equipment of claim 9, wherein the interference information is delivered to the target base station from the serving base station.

16. The user equipment of claim 9, wherein each of the serving base station and the target base station has a different cell identifier.
