Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If DRX mode and positioning measurement are designed independently, then positioning measurement can be performed, but power consumption increases significantly
Solution Approach 1:
The patent combines DRX mode operation with positioning measurement by configuring positioning reference signals to occur during DRX active times. The network device coordinates the timing of positioning reference signals with the terminal device's DRX cycle, allowing positioning measurements to be performed during wake periods without requiring additional wake-ups, thereby merging two previously independent functions into a coordinated operation that reduces power consumption while maintaining positioning capability
2Measurement precision
If terminal device wakes up frequently for positioning measurement, then positioning accuracy is maintained, but number of sleep transitions increases
Solution Approach 1:
The patent applies preliminary action by configuring positioning reference signal timing in advance based on DRX parameters. The network device determines the timing of positioning reference signals before the terminal device needs to perform measurements, aligning them with upcoming DRX active periods. This allows the terminal device to enter sleep mode confidently knowing that positioning measurements will occur during pre-scheduled wake periods, reducing unnecessary sleep transitions while maintaining positioning accuracy
