Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current sidelink channel resource schemes are used, then resource allocation can be performed, but resource allocation flexibility and efficiency are insufficient
Solution Approach 1:
The patent segments the sidelink resource pool into multiple resource units with different granularities. Each resource unit can be independently allocated and configured, allowing flexible combination to meet different service requirements. This segmentation enables the system to adapt to diverse traffic patterns while improving resource utilization efficiency through precise allocation.
Solution Approach 2:
The patent introduces dynamic resource aggregation levels that can be adjusted based on service requirements, channel conditions, and traffic load. The resource aggregation level determines how many physical resource blocks are grouped together, allowing the system to dynamically optimize between resource allocation flexibility and utilization efficiency according to real-time conditions.
2Adaptability or versatility
If finer and more flexible resource granularity is implemented, then resource allocation flexibility improves, but signaling overhead and processing complexity increase
Solution Approach 1:
The patent applies partial action by introducing resource aggregation levels that group multiple physical resource blocks into logical units. Instead of managing each individual resource block separately, the system manages aggregated units, reducing the complexity of resource configuration and signaling while maintaining flexible allocation capabilities for different service types.
3Loss of information
If current resource schemes are used, then signaling can be transmitted, but signaling overhead is increased
Solution Approach 1:
The patent merges multiple physical resource block indications into a single resource aggregation level parameter. By combining the resource allocation information for multiple resource blocks into one unified indicator, the system significantly reduces signaling overhead while preserving the ability to configure resources flexibly for different sidelink services.
