Abstract

The present invention relates to Coordinated Multiple Point (CoMP) transmission. According to an embodiment, a method for a serving base station of CoMP transmission includes sending a message to a cooperating base station of the CoMP transmission to indicate desired Non-Zero-Power Channel Status Information Reference Signal (NZP CSI RS) resources and/or Zero-Power Channel Status Information Reference Signal (ZP CSI RS) resources. The method meets new needs and facilitates CoMP transmission.

Claims

1. A method for a serving base station of Coordinated Multiple Point (CoMP) transmission, the method comprising:

sending a message to a cooperating base station of the CoMP transmission to indicate desired non-zero-power channel status information reference signal resources and/or zero-power channel status information reference signal resources.

2. The method according to claim 1, wherein the message comprises resource configuration information and subframe configuration information about the desired non-zero-power channel status information reference signal resources.

3. The method according to claim 2, wherein the message further comprises cell identification information and/or antenna port configuration information about the serving base station.

4. The method according to claim 2, wherein the message further comprises effective time of the resource configuration information and the subframe configuration information about the non-zero-power channel status information reference signal resources.

5. The method according to claim 1, wherein the message comprises zero transmission power resource configuration information and zero transmission power subframe configuration information about the desired zero-power channel status information reference signal resources.

6. The method according to claim 5, wherein the message further comprises cell identification information about the serving base station.

7. The method according to claim 5, wherein the message further comprises the zero transmission power subframe configuration information about the zero-power channel status information reference signal resources and effective time of the zero transmission power resource configuration information.

8. A method for a cooperating base station of Coordinated Multiple Point transmission, the method comprising:

sending a message to the serving base station to indicate non-zero-power channel status information reference signal resources and/or zero-power channel status information reference signal resources of the cooperating base station.

9. The method according to claim 8, further comprising:

receiving a request message about resource allocation of the CoMP transmission from the serving base station of the CoMP transmission.

10. The method according to claim 8, further comprising:

receiving a message indicating desired non-zero-power channel status information reference signal resources and/or zero-power channel status information reference signal resources from the serving base station of the CoMP transmission.

11. The method according to claim 8, wherein the message comprises resource configuration information and subframe configuration information about the non-zero-power channel status information reference signal resources.

12. The method according to claim 11, wherein the message further comprises cell identification information and/or antenna port configuration information about the cooperating base station.

13. The method according to claim 11, wherein the message further comprises the subframe configuration information about the non-zero-power channel status information reference signal resources and effective time of the resource configuration information.

14. The method according to claim 8, wherein the message comprises resource configuration information and subframe configuration information about the zero-power channel status information reference signal resources.

15. The method according to claim 14, wherein the message further comprises cell identification information about the cooperating base station.

16. The method according to claim 14, wherein the message further comprises the subframe configuration information about the zero-power channel status information reference signal resources and effective time of the resource configuration information.

17. A method for a base station of Coordinated Multiple Point transmission, the method comprising:

broadcasting non-zero-power channel status information reference signal resources in a Cooperating Set of the CoMP transmission.

18. The method according to claim 17, wherein a serving base station of the CoMP transmission integrates all configuration information in the Cooperating Set, and updates a CoMP Measurement Set correspondingly.
