receiving a CLI-RS refinement response message from the aggressor device, wherein the CLI-RS refinement response message comprises an indication that the CLI-RS refinement request message was accepted by the aggressor device; and

transmitting an updated CLI measurement configuration to the victim device based at least in part on the CLI-RS refinement response message.

2. The method of claim 1 , further comprising:

transmitting an original CLI measurement configuration to the victim device; and

receiving the original CLI measurement report from the victim device.

3. The method of claim 1 , further comprising:

receiving an updated CLI measurement report from the victim device; and

identifying an aggressor beam of the aggressor device based at least in part on the updated CLI measurement report.

4. The method of claim 1 , wherein the CLI-RS refinement response message comprises a CLI-RS transmission configuration for the aggressor device.

5. The method of claim 1 , wherein the aggressor device is a user equipment (UE) or a Next Generation NodeB (gNB).

6. The method of claim 1 , wherein the victim device is a user equipment (UE) or a Next Generation NodeB (gNB).

7. The method of claim 1 , wherein the CLI-RS refinement request message comprises a transmission information type for the aggressor device.

8. A base station, comprising:

radio front end circuitry; and

processing circuitry coupled to the radio front end circuitry and configured to:

identify an aggressor device based at least in part on an original crosslink interference (CLI) measurement report from a victim device;

transmit, via the radio front end circuitry, a CLI Reference Signal (CLI-RS) refinement request message to the aggressor device, wherein the CLI-RS refinement request message comprises an identifier for the aggressor device;

receive, via the radio front end circuitry, a CLI-RS refinement response message from the aggressor device, wherein the CLI-RS refinement response message comprises an indication that the CLI-RS refinement request message was accepted by the aggressor device; and

transmit, via the radio front end circuitry, an updated CLI measurement configuration to the victim device based at least in part on the CLI-RS refinement response message.

9. The base station of claim 8 , wherein the processing circuitry is further configured to:

transmit, via the radio front end circuitry, an original CLI measurement configuration to the victim device; and

receive, via the radio front end circuitry, the original CLI measurement report from the victim device.

10. The base station of claim 8 , wherein the processing circuitry is further configured to:

receive, via the radio front end circuitry, an updated CLI measurement report from the victim device; and

identify an aggressor beam associated with the aggressor device based at least in part on the updated CLI measurement report.

11. The base station of claim 8 , wherein the CLI-RS refinement response message comprises a CLI-RS transmission configuration for the aggressor device.

12. The base station of claim 8 , wherein the aggressor device is a user equipment (UE) or a Next Generation NodeB (gNB).

13. The base station of claim 8 , wherein the victim device is a user equipment (UE) or a Next Generation NodeB (gNB).

14. The base station of claim 8 , wherein the CLI-RS refinement request message comprises a transmission information type for the aggressor device.

15. A non-transitory computer-readable medium having instructions stored thereon that, when executed by at least one computing device, cause the at least one computing device to perform operations comprising:

identifying an aggressor device based at least in part on an original crosslink interference (CLI) measurement report from a victim device;

transmitting a CLI Reference Signal (CLI-RS) refinement request message to the aggressor device, wherein the CLI-RS refinement request message comprises an identifier for the aggressor device;

receiving a CLI-RS refinement response message from the aggressor device, wherein the CLI-RS refinement response message comprises an indication that the CLI-RS refinement request message was accepted by the aggressor device; and

transmitting an updated CLI measurement configuration to the victim device based at least in part on the CLI-RS refinement response message.

16. The non-transitory computer-readable medium of claim 15 , wherein the operations further comprise:

transmitting an original CLI measurement configuration to the victim device; and

receiving the original CLI measurement report from the victim device.

17. The non-transitory computer-readable medium of claim 15 , wherein the operations further comprise:

receiving an updated CLI measurement report from the victim device; and

identifying an aggressor beam of the aggressor device based at least in part on the updated CLI measurement report.

18. The non-transitory computer-readable medium of claim 15 , wherein the CLI-RS refinement response message comprises a CLI-RS transmission configuration for the aggressor device.

19. The non-transitory computer-readable medium of claim 15 , wherein the aggressor device is a user equipment (UE) or a Next Generation NodeB (gNB), and the victim device is a user equipment (UE) or a Next Generation NodeB (gNB).

20. The non-transitory computer-readable medium of claim 15 , wherein the CLI-RS refinement request message comprises a transmission information type for the aggressor device.
