Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensing is performed only in a single resource pool, then the complexity of resource selection is reduced, but the positioning accuracy and transmission reliability deteriorate due to limited resource options
Solution Approach 1:
The resource pool is divided into multiple segments (first resource pool for control information, second resource pool for reference signals). The device performs sensing in each segment separately, determining candidate resource sets independently. This segmentation allows comprehensive resource evaluation for accurate positioning while managing complexity through structured division of the sensing process across multiple resource pools.
2Reliability
If multiple resource pools are sensed and candidate resource sets are determined, then the transmission reliability and positioning accuracy improve, but the processing time and computational load increase
Solution Approach 1:
The device performs sensing and determines candidate resource sets in advance for multiple resource pools. By pre-evaluating resources in both the first resource pool (control information) and second resource pool (reference signals), the system prepares multiple candidate sets beforehand, reducing real-time processing delays while ensuring reliable resource selection for transmission.
3Productivity
If resource selection is optimized for high data rates, then the transmission performance improves, but the latency increases due to more extensive sensing and evaluation
Solution Approach 1:
The system dynamically selects from multiple candidate resource sets determined through sensing. The device can adaptively choose the most suitable resource pool and candidate set based on current channel conditions, traffic requirements, and latency constraints. This dynamic selection enables optimization between transmission rate and latency by flexibly utilizing resources from both the first and second resource pools.
