Abstract
Disclosed herein are system, method, and computer program product embodiments for identifying an aggressor device or an aggressor beam of an aggressor device. The embodiments further mitigate the impact of the identified aggressor device or the identified aggressor beam of the aggressor device.
Claims20
A method of mitigating an aggressor device, comprising:
- identifying the 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.
2 more elements
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.
5 more elements
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.
