Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional wireless communication systems use fixed bandwidth for positioning reference signals, then system simplicity is maintained, but positioning accuracy and spectral efficiency deteriorate due to inability to adapt to environmental conditions
Solution Approach 1:
The patent implements dynamic bandwidth adjustment for positioning reference signals based on environmental conditions. The system transitions from fixed bandwidth to variable bandwidth that adapts to factors like user mobility, signal strength, and interference levels, thereby improving positioning accuracy without requiring overly complex manual configuration mechanisms
Solution Approach 2:
The patent changes the bandwidth parameter of positioning reference signals dynamically. By adjusting the bandwidth parameter in response to environmental conditions such as signal quality and user location, the system optimizes positioning performance while maintaining automated operation through network entity control
2Productivity
If conventional systems use fixed PRS bandwidth, then implementation simplicity is maintained, but spectral efficiency deteriorates due to inability to adapt to varying communication conditions
Solution Approach 1:
The system dynamically adjusts PRS bandwidth based on real-time environmental conditions including signal strength, interference levels, and user mobility patterns. This dynamic adaptation allows the system to optimize spectral efficiency by allocating bandwidth resources more effectively across varying communication conditions
Solution Approach 2:
The patent incorporates feedback mechanisms where the network entity monitors environmental conditions and adjusts PRS bandwidth accordingly. Feedback from signal quality measurements and user location data enables continuous optimization of spectral efficiency while maintaining adaptability to changing environmental conditions
3Measurement precision
If the system performs frequent bandwidth adjustments for PRS, then positioning accuracy improves, but signaling overhead and processing time increase
Solution Approach 1:
The system performs preliminary calibration by establishing initial bandwidth settings and calibration regions before actual positioning operations. This preliminary action allows the system to pre-configure optimal parameters, reducing the need for frequent adjustments during operation and minimizing calibration time while maintaining high positioning accuracy
Solution Approach 2:
The patent implements periodic bandwidth adjustments rather than continuous adjustments. By performing adjustments at predetermined intervals or when specific trigger conditions are met, the system maintains positioning accuracy while reducing signaling overhead and processing time associated with constant reconfiguration
