Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If terminals autonomously select resources using sensing and reservation mechanism, then resource selection efficiency is improved and transmission delay is reduced, but device complexity increases
Solution Approach 1:
The terminal performs sensing operations in advance to detect resource pool status and identifies suitable resources before actual data transmission. This preliminary action allows the terminal to proactively select and reserve resources, improving resource selection efficiency and reducing transmission delay while managing device complexity through structured sensing procedures
Solution Approach 2:
The terminal autonomously performs resource selection, sensing, and reservation without requiring base station intervention for each resource allocation decision. This self-service mechanism improves productivity by enabling fast autonomous resource selection while the standardized sensing and reservation procedures help manage device complexity through systematic operations
2Loss of time
If terminals use sensing and reservation resource selection method, then transmission delay is reduced, but the complexity of resource management increases
Solution Approach 1:
The terminal performs sensing operations in advance to detect resource pool status and identifies suitable resources before actual data transmission. This preliminary action allows the terminal to proactively select and reserve resources, improving resource selection efficiency and reducing transmission delay while managing device complexity through structured sensing procedures
Solution Approach 2:
The terminal uses sensing to continuously monitor resource pool conditions and adjusts resource selection based on detected interference and occupancy levels. This feedback mechanism enables adaptive resource management that reduces transmission delay while the systematic sensing and reservation procedures help manage complexity through structured decision-making
