Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If positioning reference signal information is obtained and resource selection is performed based on RSRP thresholds, then positioning accuracy and channel measurement reliability are improved, but device complexity and processing overhead increase
Solution Approach 1:
The system performs preliminary channel measurements and RSRP threshold evaluations before final resource selection for positioning. By pre-processing channel quality information and determining candidate resources in advance, the system reduces real-time processing complexity while maintaining positioning accuracy through thorough preliminary analysis of positioning reference signal characteristics
Solution Approach 2:
The device autonomously determines its own candidate resources for positioning by evaluating channel measurements against RSRP thresholds without requiring extensive network coordination. This self-service approach allows the device to independently select suitable resources based on local channel conditions, reducing signaling overhead and processing burden on network entities
2Reliability
If candidate resources are determined based on RSRP threshold and transmission is performed, then transmission reliability is improved, but latency increases due to additional measurement and selection procedures
Solution Approach 1:
The system combines channel measurement, RSRP threshold evaluation, and resource selection into a unified resource pool management framework. By merging these functions and performing them concurrently rather than sequentially, the system reduces overall processing time while ensuring that transmission reliability requirements are met through integrated quality assessment
Solution Approach 2:
The system performs partial channel measurements on a selected subset of candidate resources rather than exhaustive measurements on all available resources. By applying RSRP thresholds to filter and evaluate only promising candidates, the system achieves sufficient transmission reliability without the time cost of complete resource space analysis
