UE Maximum Sensitivity Degradation Reporting for Interference Source Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems, particularly 5G NR, face challenges in distinguishing between sensitivity degradation caused by self-interference and other interference, leading to inaccurate network configuration decisions.
Innovation Solution
A configuration for enhanced user equipment (UE) maximum sensitivity degradation (MSD) indication that allows the UE to differentiate between MSD due to self-interference and other interference, providing a clear indication of the dominant source or amount of degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the UE reports total MSD without distinguishing interference sources, then the reporting complexity is reduced, but the network configuration accuracy deteriorates
Solution Approach 1:
The patent segments the total MSD measurement into distinct components based on interference sources. The UE separately measures and reports MSD caused by self-interference versus other interference, dividing the overall measurement task into manageable parts that can be independently analyzed and acted upon by the network
Solution Approach 2:
The patent introduces an interference source indication as an intermediary element that bridges the gap between the UE's measurements and the network's configuration decisions. This indication acts as a mediator that provides contextual information about the nature of interference, enabling more accurate network configuration without requiring complex reporting protocols
2Measurement precision
If the UE distinguishes between self-interference and other interference, then the network configuration accuracy is improved, but the measurement and reporting complexity increases
Solution Approach 1:
The measurement process is segmented into separate assessments for self-interference and other interference. The UE performs distinct measurements for each interference type and reports them separately, allowing the network to receive precise information without requiring the UE to implement complex integrated analysis
Solution Approach 2:
The interference source indication serves as an intermediary that simplifies the reporting burden on the UE while providing rich information to the network. Instead of requiring the UE to perform complex analysis and reporting, the intermediary indication conveys essential interference characteristics in a standardized format
3Productivity
If the network uses total MSD for scheduling decisions, then the scheduling process is simplified, but unnecessary configuration releases occur
Solution Approach 1:
The network uses segmented MSD information from the UE to make differentiated scheduling decisions. By separating self-interference MSD from other interference MSD, the network can apply appropriate handling strategies for each type, maintaining stable configurations when interference is manageable while releasing configurations only when necessary
Solution Approach 2:
The patent implements a feedback mechanism where the UE continuously reports interference source indications and MSD measurements to the network. This feedback loop enables the network to make informed scheduling decisions based on real-time interference conditions, adjusting configurations dynamically while avoiding unnecessary releases

AI summary
Method and apparatus for an enhanced user equipment (UE) maximum sensitivity degradation (MSD) indication are provided. The apparatus receives a request for a measurement of an MSD. The apparatus measures the MSD caused by self-interference or a different interference than the self-interference. The apparatus further reports a report including the measurement of the MSD. The measurement of the MSD includes relative information associated with a first amount of the MSD caused by the self-interference.
