Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If transmission power is increased to compensate for low transmission efficiency in wireless energy charge, then energy transmission efficiency is improved, but device complexity and power consumption increase
Solution Approach 1:
The terminal capability information is segmented into multiple fields including energy charge capability indication field, energy charge bandwidth part indication field, and energy charge numerology indication field. This segmentation allows the base station to selectively process only the relevant capability information needed for energy charge operations, reducing overall system complexity while maintaining efficient energy transmission.
Solution Approach 2:
The patent introduces specific parameter fields to indicate terminal capability for energy charge operations, including bandwidth part configuration and numerology settings. By changing and specifying these parameters, the system can optimize transmission efficiency without requiring complex terminal configurations, as the base station can adapt its transmission based on the indicated parameters.
2Measurement precision
If terminal capability information for energy charge is reported to the base station, then energy charge determination accuracy is improved, but information transmission overhead increases
Solution Approach 1:
The patent extracts only the essential capability information needed for energy charge operations from the terminal, such as energy charge capability indication, bandwidth part support, and numerology indication. By taking out only these specific required parameters and excluding unnecessary terminal capability details, the system achieves accurate capability reporting with minimized information overhead.
Solution Approach 2:
The capability indication fields are designed to serve multiple functions: they indicate terminal energy charge capability, bandwidth part configuration support, and numerology compatibility. This multi-functionality allows a single set of indication fields to provide comprehensive capability information, reducing the total information overhead while maintaining determination accuracy.
3Loss of energy
If wireless energy charge is performed with high transmission power, then energy transmission efficiency is improved, but interference with other communication devices increases
Solution Approach 1:
The patent enables dynamic adjustment of transmission parameters by providing the base station with terminal capability information regarding supported bandwidth parts and numerology. The base station can dynamically select appropriate transmission configurations that match terminal capabilities, allowing efficient energy transmission at required power levels while managing interference through adaptive parameter selection.
Solution Approach 2:
The terminal provides feedback to the base station about its energy charge capability, including supported bandwidth parts and numerology. This feedback mechanism allows the base station to adjust its transmission strategy accordingly, optimizing transmission efficiency while avoiding excessive interference by selecting appropriate frequency resources and transmission parameters based on the terminal's reported capabilities.
