Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If positioning base stations generate positioning signals using complex coding calculations, then positioning accuracy is improved, but device complexity and deployment cost increase due to requiring high-performance chips
Solution Approach 1:
The patent extracts the complex signal generation function from the positioning base station and relocates it to a separate signal generation device. The base station only needs to perform simple signal transmission, while the external device handles the computationally intensive tasks of generating positioning reference signals and calculating positioning information, thereby reducing the base station's device complexity while maintaining positioning accuracy.
Solution Approach 2:
The patent introduces an intermediary signal generation device that acts as a mediator between the positioning base station and the terminal. This intermediary device generates the positioning reference signals and calculates positioning information, allowing the base station to focus solely on signal transmission without requiring high-performance chips for complex calculations.
2Reliability
If a large number of positioning base stations with high-performance chips are deployed, then positioning function is achieved, but deployment cost increases
Solution Approach 1:
The patent extracts the expensive high-performance computing requirements from the base station deployment and consolidates them into separate signal generation devices. This allows the use of simpler, lower-cost base stations while maintaining the positioning function through the external generation of positioning reference signals and calculation of positioning information.
Solution Approach 2:
The patent makes the signal generation device a universal component that can serve multiple base stations. Instead of each base station requiring its own high-performance chip for signal generation, a single external device can generate positioning reference signals for multiple base stations, reducing the overall deployment cost while maintaining positioning reliability.
3Measurement precision
If complex coding calculations are performed at the positioning base station, then positioning measurement is accurate, but the base station requires high-performance chips increasing system cost
Solution Approach 1:
The patent introduces an intermediary signal generation device that performs the computationally intensive coding calculations for generating positioning reference signals. This intermediary handles the heavy computational load externally, allowing the base station to perform only simple signal transmission tasks, thereby reducing the computing power resources required at the base station while maintaining positioning measurement accuracy.
