Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing NR sidelink communication channels and reference signals are used, then the system maintains simplicity and compatibility, but ranging accuracy and performance are limited
Solution Approach 1:
The patent segments the sidelink communication resources by introducing dedicated ranging reference signal resources separate from existing communication channels. This segmentation allows ranging operations to use specialized resources optimized for distance and angle measurements, thereby improving ranging accuracy without compromising the simplicity of existing communication protocols.
2Measurement precision
If dedicated resources are allocated for ranging reference signals, then ranging operation accuracy is enhanced, but resource utilization efficiency decreases
Solution Approach 1:
The patent designs ranging reference signal resources that can serve multiple purposes: they function as dedicated ranging resources for accurate distance and angle measurements, while also being integrated into the existing sidelink resource pool structure. This multi-functionality allows the system to maintain high resource utilization efficiency by enabling both communication and ranging operations within a unified resource framework.
3Adaptability or versatility
If existing sidelink resource pools are used without modification, then resource management remains simple, but ranging operations cannot be performed
Solution Approach 1:
The patent applies preliminary action by pre-configuring specific resources within the sidelink resource pool for ranging reference signal transmission. These pre-allocated resources are prepared in advance with appropriate time-frequency structures, allowing ranging operations to be performed without complex real-time resource allocation decisions, thus enhancing adaptability while controlling complexity.
