Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wireless communication methods are used for device-to-device communication, then infrastructure support is required and network load increases, but communication efficiency and reliability deteriorate when base station coverage is unavailable
Solution Approach 1:
The patent introduces an intermediary device (relay device) that mediates communication between the first device and second devices. This relay device receives first indication information from the first device, determines target devices based on this information, and facilitates direct communication without requiring continuous base station infrastructure support, thereby improving reliability while reducing infrastructure dependency
Solution Approach 2:
The system enables devices to autonomously perform communication functions without relying on base station infrastructure. The first device autonomously generates first indication information containing propagation limitation data, and the relay device autonomously determines target devices and manages communication resources, allowing the network to self-organize and self-manage in infrastructure-less environments
2Area of stationary object
If device information is collected from all candidate devices, then communication coverage is maximized, but information propagation efficiency deteriorates due to excessive data processing
Solution Approach 1:
The patent applies local quality by making the first indication information generated by the first device contain specific propagation limitation information tailored to its local communication requirements. This targeted information allows the relay device to efficiently identify and select only those target devices that meet the specific propagation criteria, rather than processing information from all potential devices, thus maintaining coverage while improving efficiency
Solution Approach 2:
The system performs preliminary action by having the first device pre-generate and broadcast first indication information containing propagation limitation data before actual communication occurs. This advance preparation enables the relay device to pre-identify suitable target devices, reducing real-time processing requirements and improving overall information propagation efficiency
3Speed
If transmission resources are allocated without considering propagation limitations, then resource allocation speed increases, but communication stability deteriorates
Solution Approach 1:
The patent changes the parameter of resource allocation by incorporating propagation limitation information into the allocation decision process. The relay device uses the first indication information (containing propagation characteristics) to determine both target devices and appropriate transmission resources, ensuring that resource parameters match the propagation conditions, thereby maintaining both allocation speed and communication stability
