Abstract

An interference measurement reporting method, device, and system related to the field of communications technologies are disclosed. The method includes after receiving first information sent by a second device, sending, by a first device, at least one reported value to a third device. The first information is used to indicate an interference measurement resource to the first device. And the reported value is obtained based on an interference measurement result that is located on a portion the resource. Because the reported value is obtained based on the interference measurement performed on a specific resource of which the first device is notified previously, when the technical solution is applied to cross interference measurement, for example, inter-UE interference measurement, the first device can report accurate information about inter-UE interference status to a base station.

First claim

What is claimed is:

1. A reporting method, wherein the method comprises:
receiving, by a first device, first information sent by a second device, wherein the first information is used to indicate an interference measurement resource to the first device; and
sending, by the first device, at least one reported value and a CSI-RS resource indicator (CRI) identifier corresponding to the at least one reported value to a third device, wherein the at least one reported value is obtained based on an interference measurement result measured by the first device on a comb resource of the interference measurement resource and the CRI identifier identifies the comb resource.

2. The method according to claim 1 , wherein the method further comprises:
receiving, by the first device, second information sent by the second device, wherein the second information is used to indicate a reporting rule; and
wherein the sending, by the first device, of the at least one reported value and the identifier to a third device comprises:
sending, by the first device, the at least one reported value and the identifier to the third device based on the second information.

3. The method according to claim 1 , wherein the sending, by the first device, of the at least one reported value and the identifier to a third device comprises:
sending, by the first device, the at least one reported value and the identifier to the third device according to a predefined reporting rule.

4. The method according to claim 3 , wherein the predefined reporting rule is used to indicate at least one of a quantity of reported values, the identifier corresponding to the reported value, and a threshold; and wherein the threshold is used to select the reported value.

5. A report receiving method, wherein the method comprises:
sending, by a network side device, first information to a first device, wherein the first information is used to indicate an interference measurement resource to the first device; and
receiving, by the network side device, at least one reported value and a CSI-RS resource indicator (CRI) identifier corresponding to the at least one reported value sent by the first device, wherein the reported value is obtained based on an interference measurement result measured by the first device on a comb resource in the interference measurement resource and the identifier identifies the comb resource.

6. The method according to claim 5 , wherein the method further comprises:
sending, by the network side device, second information to the first device, wherein the second information is used to indicate a reporting rule.

7. The method according to claim 6 , wherein the reporting rule is used to indicate at least one of a quantity of reported values, the identifier corresponding to the reported value, and a threshold, and wherein the threshold is used to select the reported value.

8. The method according to claim 5 , wherein the resource comprises at least one of a time domain resource, a frequency domain resource, and a code domain resource.

9. A first device, comprising:
a memory storing instructions; and
a processor coupled to the memory configured to execute the instructions to:
receive first information sent by a second device; and
send at least one reported value and a CSI-RS resource indicator (CRI) identifier to a network side device, wherein the identifier corresponds to the at least one reported value;
wherein the first information is used to indicate an interference measurement resource to the first device, the reported value is obtained by the processor based on an interference measurement result obtained from performing inference measurement on a comb resource in the interference measurement resource, and the CRI identifier is used to identify the comb resource.

10. The first device according to claim 9 , wherein the processor coupled to the memory is further configured to execute the instructions to:
receive second information sent by the second device, wherein the second information is used to indicate a reporting rule; and
send at least one reported value and the identifier to the network side device based on the second information.

11. The first device according to claim 10 , wherein the processor is configured to execute the instructions to:
send the at least one reported value and the identifier to the network side device according to a predefined reporting rule.

12. The first device according to claim 11 , wherein the reporting rule or the predefined reporting rule is used to indicate at least one of a quantity of reported values, the identifier corresponding to the reported value, and a threshold, and wherein the threshold is used to select the reported value.

13. A device, comprising:
a memory storing instructions; and
a processor coupled to the memory configured to execute the instructions to:
send first information to a first device; and
receive at least one reported value and a CSI-RS resource indicator (CRI) identifier sent by the first device, wherein the identifier corresponds to the at least one reported value;
wherein the first information is used to indicate an interference measurement resource to the first device; and the reported value indicates an interference measurement result that is obtained by the first device by performing an interference measurement on a comb resource in the interference measurement resource; and wherein the CRI identifier identifies the comb resource.

14. The device according to claim 13 , wherein the processor coupled to the memory is further configured to execute the instructions to:
send second information to the first device, wherein the second information is used to indicate a reporting rule.

15. The device according to claim 13 , wherein the reporting rule is used to indicate at least one of a quantity of reported values, a resource identifier corresponding to the reported value, and a threshold, and wherein the threshold is used to select the reported value.

16. The device according to claim 13 , wherein the resource comprises at least one of a time domain resource, a frequency domain resource, and a code domain resource.
