INTER-UE CROSS-LINK INTERFERENCE (CLI) MITIGATION FOR BASE STATION IN FULL DUPLEX MODE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17531359 titled 'INTER-UE CROSS-LINK INTERFERENCE (CLI) MITIGATION FOR BASE STATION IN FULL DUPLEX MODE

Simplified Explanation

The present disclosure is about configuring a report that accurately characterizes cross-link interference (CLI) experienced by a victim user equipment (UE) from an aggressor UE. The victim UE measures interference metrics on different measurement resources based on a configuration provided by the base station. The victim UE then transmits a CLI report to the base station, including a subset of the interference metrics and associated quasi-co-location (QCL) information.

  • The patent application focuses on addressing cross-link interference (CLI) experienced by a victim user equipment (UE) from an aggressor UE.
  • It proposes a configuration for CLI reporting that accurately characterizes the interference experienced by the victim UE for different beams.
  • The base station transmits the configuration to the victim UE, which includes quasi-co-location (QCL) information associated with each measurement resource.
  • The victim UE measures interference metrics on the specified measurement resources based on the provided configuration and QCL information.
  • The victim UE then transmits a CLI report to the base station, including a subset of the interference metrics and the corresponding QCL information.

Potential Applications

  • This technology can be applied in wireless communication systems to improve the management of cross-link interference between user equipment.
  • It can be used in cellular networks to enhance the performance and reliability of communication between base stations and user equipment.
  • The technology can be implemented in 5G and future wireless networks to optimize the utilization of available resources and improve overall network efficiency.

Problems Solved

  • The technology solves the problem of accurately characterizing cross-link interference (CLI) experienced by a victim user equipment (UE) from an aggressor UE.
  • It addresses the challenge of configuring a CLI report that provides reliable information about the interference metrics for different beams.
  • The technology solves the problem of managing and mitigating cross-link interference in wireless communication systems, which can degrade the quality of service and impact network performance.

Benefits

  • The configuration of a CLI report with accurate characterization of cross-link interference allows for better management and mitigation of interference in wireless communication systems.
  • By providing quasi-co-location (QCL) information associated with each measurement resource, the technology enables the victim UE to measure interference metrics more effectively.
  • The CLI report with a subset of interference metrics and corresponding QCL information allows the base station to analyze and address cross-link interference more efficiently, leading to improved network performance and user experience.


Original Abstract Submitted

A victim user equipment (UE) may experience cross-link interference (CLI) from transmissions from an aggressor UE. The present disclosure provides for configuration of a CLI report that accurately characterizes the CLI experienced by the victim UE for different beams. A base station may transmit to the victim UE, a configuration for CLI reporting associated with a plurality of measurement resources, the configuration identifying a quasi-co-location (QCL) information associated with each measurement resource. The victim UE may measure interference metrics on the plurality of measurement resources based on the configuration for CLI reporting and the QCL information associated with each measurement resource. The victim UE may transmit a CLI report to the base station, the CLI report including a subset of the interference metrics associated with reported measurement resources and identifying the QCL information associated with the reported measurement resources.
