Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If AI models are continuously executed in wireless communication systems, then system automation and functionality are improved, but model effectiveness deteriorates due to user equipment movement and environmental changes
Solution Approach 1:
The patent implements dynamic model adjustment by continuously monitoring model effectiveness metrics and automatically triggering adjustment operations when effectiveness degrades below thresholds. This transforms the static AI model execution into a dynamic system that adapts to changing wireless environments through real-time effectiveness evaluation and automated model retraining or switching.
Solution Approach 2:
The patent establishes a feedback mechanism where model effectiveness is continuously evaluated based on prediction accuracy, loss functions, and performance metrics. This feedback loop triggers automated model adjustment operations when effectiveness deteriorates, creating a closed-control system that maintains model reliability through continuous monitoring and self-correction.
2Reliability
If AI model adjustment operations are frequently performed, then model effectiveness is maintained, but system productivity deteriorates due to additional training and switching overhead
Solution Approach 1:
The patent adjusts model parameters dynamically by changing the frequency and type of model adjustment operations based on effectiveness degradation rates. When effectiveness slowly degrades, less intensive adjustments are performed; when rapid degradation is detected, more frequent adjustments are triggered. This parameter-based control optimizes the balance between maintaining effectiveness and minimizing adjustment overhead.
Solution Approach 2:
The patent implements partial model adjustment by selectively adjusting only certain model components or parameters rather than complete retraining, and by performing adjustments at optimized frequencies based on effectiveness thresholds. This partial action approach maintains model effectiveness while reducing the computational overhead compared to full frequent retraining.
3Adaptability or versatility
If model adjustment operations are performed, then adaptability to environmental changes is improved, but device complexity increases due to multiple adjustment mechanisms
Solution Approach 1:
The patent implements a universal model adjustment framework that handles multiple adjustment operations (full retraining, fine-tuning, parameter optimization, model switching) through a single centralized control mechanism. This multi-functional approach enables the system to adapt to various environmental conditions and model degradation scenarios while avoiding the complexity of separate independent adjustment systems for each operation type.

AI summary
This application discloses a method and apparatuses for adjusting a model, a method and apparatus for transmitting information, and related devices. The method for adjusting a model includes: executing, by a first device, a model adjustment operation on a first Artificial Intelligence (AI) model. The model adjustment operation includes one of the following: finetuning the first AI model; switching the first AI model into a second AI model; falling back to a target functional module for operation, where the target functional module is a module that does not use an AI model; finetuning the first AI model, and switching the first AI model into a second AI model; finetuning the first AI model, and falling back to the target functional module for operation; or stopping execution of a first function, where the first function is a function that is completed by the first AI model.
