V2X Resource Pool Selection by Geographic Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently transmitting vehicle-to-everything (V2X) signals, particularly in reducing Inter-Cell Interference (ICI) by effectively selecting resource pools based on vehicle position information.
Innovation Solution
The method involves dividing resource regions according to the traveling direction or mobility of User Equipment (UE), allowing for the selection of appropriate resource pools for data transmission, thereby reducing ICI.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If resource pools are selected without considering vehicle position information, then resource allocation is simple, but Inter-Cell Interference (ICI) increases
Solution Approach 1:
The patent applies local quality by dividing the resource pool into multiple sub-resource pools based on geographic location. Each UE selects resources from a sub-resource pool corresponding to its current location, ensuring that UEs in different geographic areas use different resources. This location-based differentiation reduces ICI while maintaining manageable complexity through structured resource organization.
Solution Approach 2:
The patent segments the overall resource pool into multiple sub-resource pools according to geographic location. This segmentation allows independent resource allocation in different spatial regions, reducing interference between cells. The segmented structure enables UEs to select resources locally without affecting other regions, thereby reducing ICI while keeping the selection process organized and manageable.
2Object-affected harmful factors
If resource pools are divided according to position information, then ICI is reduced, but resource allocation complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-dividing the resource pool into sub-resource pools based on geographic location before actual resource allocation. This pre-organization of resources by location eliminates the need for complex real-time calculations during resource selection. UEs can directly select from pre-defined sub-resource pools corresponding to their location, reducing ICI while keeping the allocation process simple and efficient.
Solution Approach 2:
The patent implements local quality by assigning different resource subsets to different geographic locations. Each location has its own optimized resource pool, allowing UEs to select resources tailored to their specific geographic context. This localized resource allocation reduces ICI by ensuring spatial separation of resource usage while maintaining simplicity through pre-defined location-specific resource sets.
3Reliability
If traditional resource allocation is used without mobility consideration, then resource management is simple, but transmission reliability decreases
Solution Approach 1:
The patent applies dynamics by enabling UEs to dynamically select from multiple sub-resource pools based on their current geographic location and mobility state. Instead of fixed resource allocation, the system allows flexible adaptation to changing UE positions. This dynamic selection improves transmission reliability by ensuring UEs continuously use appropriate resources for their current location while maintaining manageable complexity through pre-defined resource pools.
Solution Approach 2:
The patent uses preliminary action by pre-configuring multiple sub-resource pools corresponding to different geographic locations and mobility states. This advance preparation allows UEs to quickly and reliably select appropriate resources based on their current state without complex real-time calculations. The pre-organized resource structure improves transmission reliability while keeping resource management simple and efficient.

AI summary
One embodiment of the present invention relates to a method by which a terminal transmits and receives a vehicle to everything (V2X) related signal in a wireless communication system, comprising the steps of: selecting a resource pool by comparing at least one piece of measurement information with a resource pool parameter; and transmitting data by using the resource pool, wherein the at least one piece of measurement information is related to a geographical location of the terminal.
