Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a ranging service and sidelink positioning service are introduced as new scenarios, then the service functionality and application versatility are improved, but the network device complexity and service exposure difficulty increase
Solution Approach 1:
The patent segments the ranging service exposure into distinct message types (request messages, response messages, measurement reports) and separate processing flows (terminal-based measurement, network-based measurement, combined measurement). This segmentation allows the network device to handle different service types through standardized interfaces, reducing the perceived complexity while maintaining versatility.
Solution Approach 2:
The network device is designed with universal service exposure capabilities that can handle multiple service types (ranging, sidelink positioning, future services) through a unified message framework. The same basic message structures and processing logic are reused across different service scenarios, allowing the system to maintain adaptability without proportionally increasing complexity.
2Measurement precision
If ranging-based service measurement is performed between terminals, then the measurement precision and service accuracy are improved, but the device complexity and operation difficulty increase
Solution Approach 1:
The network device acts as an intermediary that coordinates terminal measurements, collects measurement reports, and processes results. Terminals perform standardized measurements using provided reference signals, then report results to the network device which handles the complex calculation and integration logic. This mediator approach maintains high measurement precision while simplifying terminal operation.
Solution Approach 2:
The network device performs preliminary actions by configuring reference signals, pre-calculating measurement parameters, and establishing measurement procedures before actual ranging occurs. This preparation work reduces the operational burden on terminals during the actual measurement process, maintaining precision while improving ease of operation.
