CLI Reporting Trigger Conditions for Low-Interference Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional CLI reporting techniques only enable victim UEs to indicate resources with high CLI measurements, failing to provide information on preferred resources with low CLI, which hinders network scheduling efficiency.
Innovation Solution
Victim UEs are enabled to report least-interfering CLI resources by performing measurements and transmitting reports when CLI falls below a threshold or meets specific trigger conditions, allowing the network to schedule communications on resources with sufficient performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If victim UEs report only high CLI resources, then reporting overhead is reduced, but network scheduling efficiency deteriorates due to lack of information on preferred resources
Solution Approach 1:
Instead of reporting only high CLI resources (problematic resources), the patent inverts the approach by enabling victim UEs to report least-interfering CLI resources (preferred resources). This inversion provides the network with positive information about good resources for scheduling, thereby improving network scheduling efficiency while reducing the information loss about preferred resources.
2Loss of information
If victim UEs report all CLI resources, then complete information is provided, but signaling overhead increases
Solution Approach 1:
The patent extracts only the most relevant information for network scheduling by enabling victim UEs to report specifically the least-interfering CLI resources rather than all CLI resources. This extraction provides sufficient information for the network to make scheduling decisions while significantly reducing the signaling overhead compared to reporting all resources.
Solution Approach 2:
The patent applies local quality by differentiating between types of CLI resources and reporting only those with specific characteristics (least-interfering resources). This selective reporting based on local quality attributes provides targeted information that improves scheduling efficiency without the overhead of comprehensive reporting.
3Reliability
If CLI reporting is performed continuously, then real-time CLI information is available, but energy consumption increases
Solution Approach 1:
The patent implements periodic action by triggering CLI reporting only under specific conditions (when CLI threshold is exceeded or event-triggered conditions are met) rather than continuously. This conditional periodic reporting maintains real-time CLI information availability for reliable scheduling decisions while significantly reducing energy consumption compared to continuous reporting.
Solution Approach 2:
The patent enables the system to self-regulate reporting based on configured thresholds and events. The victim UE autonomously determines when reporting is necessary based on local measurements and trigger conditions, eliminating the need for continuous network-controlled reporting and reducing overall energy consumption while maintaining information reliability.
Data Source
AI summary
Methods, systems, and devices for wireless communications are described. A first user equipment (UE) (e.g., “victim” UE) may receive control signaling indicating a cross-link interference (CLI) reporting configuration associated with a set of CLI resources, where the CLI resources are associated with varying levels of CLI at the first UE. The first UE may perform CLI measurements on signals received from a second UE (e.g., “aggressor” UE) within the set of CLI interference resources based on the CLI reporting configuration. The first UE may then transmit, based on the CLI measurements, a CLI report identifying a CLI resource from the set of CLI resources, wherein the CLI resource is associated with a CLI measurement that fails to satisfy a CLI threshold, or wherein the CLI resource is associated with a lower level of CLI as compared to other CLI resources within the set of CLI resources.
