Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no reporting method for Layer 1-Cross-link interference (L1-CLI) measurement in existing technologies, limiting effective interference suppression and resource management.
Innovation Solution
A method and device for reporting L1-CLI measurement values by sending a first measurement value and difference information, where the difference information quantizes the difference between maximum or minimum L1-CLI values, using varying step sizes to enhance accuracy and enable precise interference management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional measurement reporting methods are used, then the system is simple to implement, but L1-CLI measurement reporting cannot be performed at all
Solution Approach 1:
The measurement value reporting is segmented into two parts: a first measurement value (e.g., maximum or minimum L1-CLI measurement) and difference information representing the quantized difference between the first measurement value and other measurement values. This segmentation enables L1-CLI measurement reporting functionality while managing complexity by dividing the reporting into manageable components.
Solution Approach 2:
The patent changes the parameter representation by using difference information with quantized values instead of reporting all raw measurement values directly. The difference information encodes the relative differences between measurement values using optimized bit representations, enabling measurement reporting capability while controlling the complexity of the reporting mechanism.
2Loss of information
If all N measurement values are reported directly, then complete measurement information is provided, but signaling overhead increases significantly
Solution Approach 1:
The patent extracts only the essential information needed for interference management: the first measurement value (maximum or minimum) and the difference information representing relative differences. By taking out only the critical measurement data rather than reporting all N values, the patent maintains measurement information completeness for interference suppression decisions while significantly reducing signaling overhead.
Solution Approach 2:
Instead of reporting absolute values for all measurements, the patent inverts the approach by reporting one reference measurement value and encoding other values as differences relative to this reference. This inversion reduces the amount of information that needs to be transmitted while preserving the ability to reconstruct complete measurement information when needed.

AI summary
The present disclosure discloses an information processing method, device, and a readable storage medium, relating to the technical field of communications, so as to realize the reporting of measurement values on L1-CLI measurement resources. The method includes: sending a first measurement value and difference information to a network device, where the difference information is used to indicate a quantized value corresponding to a difference between a second measurement value and the first measurement value, the first measurement value is a maximum value or a minimum value among N measurement values of layer 1 cross-link interference L1-CLI, N is an integer greater than 1, and the second measurement value is a measurement value other than the first measurement value among the N measurement values.
