Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement quality reporting is enhanced to include confidence levels and relative quality metrics, then positioning accuracy and reliability are improved, but signaling overhead increases
Solution Approach 1:
The measurement quality reporting is segmented into multiple components: absolute quality metrics (RSRP, RSRQ) and relative quality metrics (quality difference compared to reference). This segmentation allows the system to report only necessary quality information based on configuration, reducing overall signaling overhead while maintaining positioning accuracy.
Solution Approach 2:
The reporting mechanism is made dynamic through confidence level configuration. The UE adapts its reporting behavior based on configured confidence thresholds (e.g., 80%, 85%, 90%, 95%), transmitting detailed quality information only when confidence requirements are met. This dynamic adaptation reduces unnecessary signaling while ensuring positioning reliability.
2Reliability
If both absolute and relative measurement quality reporting are implemented, then positioning reliability is improved, but device complexity increases
Solution Approach 1:
The measurement quality reporting apparatus is designed with multi-functionality to handle both absolute and relative quality reporting within a unified framework. The same UE apparatus performs RSRP/RSRQ measurements, calculates relative quality differences, and adapts reporting based on confidence level configurations, reducing the need for separate dedicated mechanisms and thereby limiting complexity increase.
Solution Approach 2:
The UE apparatus autonomously determines which quality metrics to report based on pre-configured confidence levels and current measurement conditions. The device self-manages the selection between absolute and relative reporting modes without requiring complex external control, simplifying the overall system architecture while maintaining high positioning reliability.
3Measurement precision
If confidence level configuration is added to measurement reporting, then measurement quality assessment is improved, but use of energy increases
Solution Approach 1:
Measurement quality reporting is performed periodically based on configured confidence level thresholds rather than continuously. The UE evaluates measurements at periodic intervals and transmits reports only when confidence requirements are satisfied, reducing energy consumption compared to continuous reporting while maintaining accurate quality assessment.
Solution Approach 2:
The confidence level parameter is used to dynamically control reporting behavior. By adjusting the confidence threshold parameter (80%, 85%, 90%, 95%), the system optimizes the balance between measurement quality assessment accuracy and energy consumption, transmitting detailed reports only when necessary to meet positioning reliability requirements.
