Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If AI/ML models are activated to improve performance in wireless communication networks, then the performance and accuracy of communication tasks are improved, but the computational resources, energy consumption, and system complexity increase
Solution Approach 1:
The system dynamically changes parameters such as model activation status, model switching decisions, and resource allocation based on network conditions, user requirements, and performance metrics. This allows the system to adapt AI/ML model usage to different operational scenarios, activating models only when beneficial and deactivating them when resources are constrained or performance requirements are met by simpler methods
Solution Approach 2:
The system implements dynamic model selection and switching mechanisms that continuously evaluate the trade-off between performance benefits and resource costs. The apparatus monitors network state, communication task requirements, and model performance metrics in real-time, dynamically deciding which AI/ML models to activate, deactivate, or switch between, thereby optimizing the balance between reliability improvement and system complexity management
2Adaptability or versatility
If multiple AI/ML models are maintained for different tasks and conditions, then the adaptability and versatility of the system are improved, but the resource requirements and activation overhead increase
Solution Approach 1:
The system segments AI/ML models into task-specific and condition-specific categories, maintaining separate models for different communication tasks (e.g., beam management, channel estimation, interference mitigation) and different network conditions (e.g., urban, rural, indoor environments). This segmentation allows the system to activate only the specific model needed for the current task and condition, rather than maintaining all models in memory and ready to execute, thereby reducing energy consumption while preserving adaptability
Solution Approach 2:
The system performs preliminary evaluation of model suitability based on predicted network conditions and task requirements before actual model activation. The apparatus uses historical data, current network state, and task characteristics to pre-assess which models are likely to be beneficial, preparing and activating only those models in advance, thus avoiding the energy cost of activating unnecessary models while ensuring adaptability when conditions change
3Productivity
If AI/ML models are frequently switched to optimize performance, then the performance optimization and resource utilization are improved, but the signaling overhead and latency increase
Solution Approach 1:
The system implements periodic model evaluation and switching at predetermined intervals or trigger events (e.g., changes in network conditions, completion of current task, resource threshold crossings) rather than continuous monitoring and switching. This periodic approach reduces the signaling overhead and processing latency associated with frequent model switching decisions, while still maintaining effective resource utilization by switching models at appropriate intervals when performance benefits are most likely to be achieved
