Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If sidelink control information is transmitted on sub-channels corresponding to time and frequency resources for sidelink reference signal transmission, then resource allocation efficiency and positioning accuracy are improved, but the complexity of determining and managing these corresponding resources increases
Solution Approach 1:
The patent merges the transmission of sidelink control information with sidelink reference signal transmission by mapping control information to sub-channels that correspond to time and frequency resources of reference signals. This integration allows simultaneous transmission of both control information and reference signals, improving resource allocation efficiency while reducing overall system complexity through unified resource management.
Solution Approach 2:
The patent introduces sub-channels as intermediary elements that serve as correspondences between control information transmission and reference signal resources. These sub-channels act as mediators that enable terminal devices to determine reference signal resources based on control information transmission locations, simplifying the resource management process while maintaining high allocation efficiency.
2Measurement precision
If terminal devices determine sidelink reference signal resources based on sub-channel location, then positioning accuracy is improved, but the time required for resource determination and location calculation increases
Solution Approach 1:
The patent performs preliminary mapping of sub-channels to time and frequency resources for sidelink reference signal transmission. This pre-establishment of correspondence relationships allows terminal devices to quickly determine reference signal resources based on sub-channel location without performing complex real-time calculations, thereby reducing determination time while maintaining positioning accuracy.
Solution Approach 2:
The patent uses sub-channels as copies or representations of the time and frequency resources for sidelink reference signal transmission. By transmitting control information on sub-channels that correspond to reference signal resources, terminal devices can determine reference signal locations through simple sub-channel mapping rather than complex signal analysis, reducing processing time while maintaining measurement precision.
