Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If base stations are equipped with wireless charging capability using Massive MIMO technology, then charging power and service capability are improved, but terminal ability to determine and select charging base stations deteriorates due to lack of capability indication mechanisms
Solution Approach 1:
The capability information is segmented into specific parameters including charging power, duration, and frequency that can be independently determined and evaluated by the terminal, allowing selective base station selection based on individual charging requirements
Solution Approach 2:
Capability information acts as an intermediary between the base station's wireless charging capability and the terminal's cell selection decision, enabling the terminal to make informed choices without direct complex interactions with the base station
2Measurement precision
If base stations broadcast detailed capability information, then terminal charging selection accuracy is improved, but information overhead and system complexity worsen
Solution Approach 1:
Only the essential charging capability parameters (power, duration, frequency) are extracted and transmitted to the terminal, filtering out unnecessary information to maintain accuracy while minimizing overhead
Solution Approach 2:
The capability information is represented through specific measurable parameters that can be efficiently encoded and transmitted, transforming complex base station capabilities into concise quantifiable data
