Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single selection procedure is used for D2D communication, then the device complexity is reduced, but the resource utilization efficiency deteriorates due to waste of wireless frequency spectrum resources
Solution Approach 1:
The patent implements dynamic selection procedure determination by having the UE select from multiple available selection procedures based on current communication conditions, node characteristics, and environmental factors. This dynamic adaptation allows the system to optimize resource utilization for each specific scenario rather than using a fixed single procedure, thereby resolving the contradiction between simplicity and efficiency.
Solution Approach 2:
The patent changes the parameter of selection procedure type based on different communication scenarios, node capabilities, and environmental conditions. By allowing the selection procedure parameter to vary dynamically, the system can adapt to different situations and improve resource utilization without requiring permanently complex multi-procedure infrastructure.
2Productivity
If multiple selection procedures are implemented for D2D communication, then the resource utilization efficiency is improved, but the device complexity increases
Solution Approach 1:
The system dynamically determines which selection procedure to use based on current conditions, rather than implementing all procedures simultaneously in a static manner. This dynamic approach allows multiple procedures to be available in the protocol stack but only activates the appropriate ones needed for current scenarios, improving resource utilization while managing device complexity through conditional execution.
Solution Approach 2:
The patent segments the selection procedure implementation into multiple independent procedures that can be individually selected and executed. Rather than one monolithic complex procedure, the system divides functionality into separate selectable procedures, allowing efficient resource utilization through appropriate procedure selection while keeping each individual procedure's complexity manageable.
3Productivity
If D2D communication shares pre-existing wireless frequency spectrum resources, then the spectrum utilization is improved, but the transmission reliability deteriorates due to potential interference with existing wireless communication systems
Solution Approach 1:
The patent implements feedback mechanisms where UEs monitor communication conditions, detect potential interference, and adjust their D2D communication parameters accordingly. This feedback loop allows the system to share spectrum resources effectively while maintaining transmission reliability by detecting and responding to interference conditions in real-time.
Solution Approach 2:
The system dynamically adjusts D2D communication parameters such as transmission power, resource selection, and modulation schemes based on detected interference levels and communication conditions. This dynamic adaptation enables reliable D2D communication on shared spectrum by continuously optimizing parameters to avoid interference with existing wireless systems while maintaining spectrum utilization efficiency.
