Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sensing-based schemes or pre-configured allocations are used for radio resource management in out-of-coverage scenarios, then resource allocation can be achieved without base station assistance, but interference and resource wastage increase due to inability to adapt to actual vehicle presence and composition
Solution Approach 1:
The patent implements dynamic radio resource management by enabling vehicles to adjust their resource allocation and scheduling based on real-time detection of other vehicles' presence and composition. The system transitions from static pre-configured allocations to dynamic adaptations where transmission parameters, resource blocks, and scheduling decisions are modified according to the detected traffic situation, allowing optimal resource utilization without base station assistance.
Solution Approach 2:
The patent enables vehicles to autonomously manage their own radio resources by detecting the presence and composition of surrounding vehicles through wireless messages. Each vehicle independently analyzes the traffic situation and adjusts its resource allocation without requiring external base station control,实现ing self-service radio resource management that adapts to actual conditions while avoiding resource wastage.
2Productivity
If larger subset of radio resources is used to increase usage of available resources, then resource utilization improves, but collision likelihood increases in high-density vehicle situations
Solution Approach 1:
The patent dynamically adjusts the subset of radio resources used for transmission based on the detected composition and density of surrounding vehicles. In low-density situations, vehicles utilize larger resource subsets to maximize resource utilization. In high-density situations, the system automatically reduces the resource subset size to minimize collisions, achieving dynamic optimization of both productivity and reliability.
Solution Approach 2:
The patent changes key transmission parameters including the size of radio resource subsets, transmission power, and scheduling intervals based on the detected vehicle presence and composition. By adjusting these parameters dynamically according to traffic density, the system optimizes resource utilization while maintaining reliable communication by reducing collision probability in congested scenarios.
3Reliability
If smaller subset of radio resources is used to reduce collision likelihood, then communication reliability improves, but resource usage efficiency decreases
Solution Approach 1:
The patent implements dynamic resource allocation where the size of the radio resource subset is adjusted in real-time based on detected vehicle density and composition. In sparse traffic conditions, the system expands the resource subset to maximize efficiency. In dense traffic conditions, it contracts the subset to ensure reliability, achieving optimal balance between productivity and reliability through continuous adaptation.
Solution Approach 2:
The patent modifies transmission parameters including resource subset size, modulation schemes, and retransmission intervals based on the detected traffic situation. By changing these parameters dynamically, the system ensures high communication reliability in congested areas while maintaining efficient resource usage in less crowded conditions, avoiding the need to consistently use conservative small resource subsets.
4Extent of automation
If vehicles coordinate resource scheduling without base station assistance, then autonomy and response time improve, but system complexity increases due to need for inter-vehicle coordination protocols
Solution Approach 1:
The patent enables vehicles to autonomously perform resource scheduling and coordination functions that traditionally required base station control. Each vehicle independently detects surrounding traffic, analyzes the situation, and makes scheduling decisions based on pre-configured rules and real-time conditions, achieving high automation without external assistance while managing complexity through standardized protocols.
Solution Approach 2:
The patent uses standardized wireless messages and pre-configured coordination protocols as intermediaries to facilitate inter-vehicle communication and resource scheduling. These standardized protocols act as mediators that enable autonomous vehicles to coordinate their resource usage without requiring complex ad-hoc negotiation mechanisms, reducing system complexity while maintaining high automation levels.
