Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for reporting user equipment (UE) capability in cellular networks are inadequate for dynamically varying capabilities, particularly in AI-enabled scenarios, where computing power, storage, and communication capabilities also need to be reported.
Innovation Solution
A method for reporting UE capability that involves dynamically varying capabilities, such as processor load, remaining storage, communication bandwidth, and battery level, to the network device when specific reporting conditions are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If UE capability is reported frequently to ensure real-time accuracy, then the accuracy of capability information is improved, but the signaling overhead and network resource consumption increase
Solution Approach 1:
The patent implements dynamic capability reporting where the UE transitions from static periodic reporting to event-triggered reporting. The UE monitors capability metrics (CPU load, memory usage, battery level) and only reports when changes exceed predefined thresholds, making the reporting system adaptive to actual capability variations rather than following fixed time intervals.
Solution Approach 2:
The patent changes the reporting parameter from time-based (periodic) to threshold-based (event-triggered). Instead of reporting at fixed intervals, the system uses capability threshold values as triggers, where reporting occurs only when capability metrics cross specified thresholds, thereby optimizing the balance between information freshness and signaling reduction.
2Reliability
If UE capability reporting is performed continuously to maintain up-to-date information, then the reliability of coordination is improved, but the energy consumption of the UE increases
Solution Approach 1:
The patent implements selective periodic reporting where the UE periodically monitors its capability metrics but only initiates reporting actions when capability changes exceed predefined thresholds. This transforms continuous reporting into event-driven periodic reporting, reducing energy consumption while maintaining coordination reliability through threshold-based triggers.
Solution Approach 2:
The UE autonomously determines when reporting is necessary by self-monitoring its capability metrics against predefined thresholds. The system enables the UE to self-manage reporting decisions based on its own state, eliminating the need for continuous network scheduling and reducing energy consumption through intelligent self-triggered reporting.
3Adaptability or versatility
If detailed UE capability information is reported to enhance network decision-making, then the adaptability of network resource allocation is improved, but the complexity of capability reporting increases
Solution Approach 1:
The patent segments capability reporting into multiple threshold levels (first threshold for normal operation, second threshold for abnormal conditions). Different capability metrics (CPU load, memory usage, battery level) are monitored independently with their own thresholds, allowing the network to receive granular, segmented information about specific capability dimensions rather than overwhelming detailed reports.
Solution Approach 2:
The patent applies different reporting thresholds and criteria to different capability metrics based on their local characteristics. Each capability dimension (computing power, storage, communication, battery) has customized threshold values and reporting rules tailored to its specific variation patterns and importance, enabling targeted reporting without uniform complexity across all parameters.
