V2X Resource Selection Using Direction and Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current V2X communication systems face challenges in resource allocation and utilization due to varying traffic conditions and high terminal densities, leading to potential collisions and inefficiencies in resource usage, particularly in urban areas and emergency situations.
Innovation Solution
The implementation of direction-dependent and density-dependent radio resource allocation methods in wireless terminals and cellular radio access networks, where resources are selected based on geographical region, travel direction, and communication density to minimize interference and optimize resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resource pools are allocated without considering geographical region and travel direction, then resource allocation is simple, but collision probability increases in high-density areas
Solution Approach 1:
The patent applies local quality by allocating different resource pools to different geographical regions and travel directions. Each region-direction combination has its own dedicated resource pool, ensuring that local communication needs are met with appropriate resources while avoiding conflicts in high-density areas.
Solution Approach 2:
The patent segments the available radio resources into multiple resource pools, where each pool is associated with specific geographical regions and travel directions. This segmentation allows independent management and allocation of resources for different spatial contexts, reducing collisions while maintaining overall system efficiency.
2Object-affected harmful factors
If directional resource allocation is implemented, then collision avoidance improves, but system complexity increases
Solution Approach 1:
The patent assigns specific resource pools to specific travel directions within geographical regions. By making resource allocation direction-dependent, the system reduces interference between vehicles traveling in different directions while maintaining manageable complexity through pre-defined resource pool associations.
3Productivity
If multiple resource pools are used for different regions, then resource utilization efficiency improves, but information processing requirements increase
Solution Approach 1:
The patent pre-establishes the mapping between geographical regions, travel directions, and resource pools before actual communication occurs. This preliminary configuration allows vehicles to autonomously select appropriate resources based on their current region and direction without requiring complex real-time processing or extensive information exchange.
