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 is insufficient and signaling overhead increases
Solution Approach 1:
The patent segments the sidelink channel resources into resource units with finer granularity in both time and frequency domains. This segmentation allows for more flexible and precise resource allocation, enabling the system to allocate resources in smaller, more manageable units that can be tailored to specific communication needs, thereby improving adaptability while reducing unnecessary signaling overhead.
Solution Approach 2:
The patent implements dynamic resource allocation mechanisms that adapt to changing channel conditions and traffic requirements. The resource configuration can be adjusted in real-time based on network conditions, user demands, and interference levels, providing the flexibility needed to optimize performance while minimizing signaling overhead through intelligent, context-aware allocation decisions.
2Productivity
If current sidelink channel resource schemes are used, then resource allocation can be performed, but processing complexity increases
Solution Approach 1:
By dividing resources into standardized units with clear definitions in time and frequency domains, the patent simplifies the processing required for resource allocation. The segmented structure enables more efficient resource utilization through precise control while reducing the computational complexity associated with managing larger, less granular resource blocks.
Solution Approach 2:
The patent changes the fundamental parameters of resource configuration by introducing finer granularity in time and frequency domains. This parameter transformation enables more efficient resource utilization through better matching of resources to actual communication needs, while the standardized new parameter structure actually reduces processing complexity compared to managing coarser, less flexible resource allocations.
3Productivity
If finer resource granularity is implemented, then resource utilization efficiency improves, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing resources into fine-grained units with well-defined time and frequency characteristics. This segmentation improves resource utilization efficiency by enabling precise allocation matched to actual traffic requirements. The structured segmentation approach, with clear unit definitions and patterns, actually reduces configuration complexity by providing a systematic framework rather than requiring complex ad-hoc configurations.
Solution Approach 2:
The patent creates a universal resource unit structure that can serve multiple functions and scenarios. The standardized fine-grained resource units can be applied across different sidelink communication scenarios and configurations, improving resource utilization efficiency while reducing overall system complexity through reuse of the same fundamental building blocks across multiple applications.
