V2X Resource Pool Allocation for Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In V2X communication, the coexistence of different communication methods such as V2V and V2P in a shared resource pool leads to adverse effects due to parameter differences, resulting in inefficient frequency resource use and potential interference.
Innovation Solution
A mechanism is provided to allow signals from different V2X communication methods to coexist in a resource pool by implementing a base station and terminal apparatus configuration that dynamically allocates resource pools based on communication status and priority control, ensuring efficient use and minimizing interference.

Engineering Contradiction Analysis
1Productivity
If a resource pool is shared by V2V communication and V2P communication, then resource utilization efficiency is improved, but communication reliability deteriorates due to parameter differences causing interference
Solution Approach 1:
The resource pool is segmented into multiple resource pool sets, where each set is configured with specific parameters (data transmission period, resource allocation) suitable for particular communication methods. V2V communication and V2P communication can be assigned to different segmented resource pool sets, allowing them to share the overall resource pool while maintaining separate parameter configurations to avoid interference and ensure reliability for each communication type.
2Adaptability or versatility
If different communication methods with different parameters are allowed in a common resource pool, then communication versatility is improved, but signal interference increases
Solution Approach 1:
Different resource pool sets within the shared resource pool are configured with different local qualities (parameters) according to the specific needs of V2V or V2P communication. Each communication method can access resource pool sets with parameters optimized for its characteristics, allowing versatility in supporting multiple communication types while minimizing interference through parameter differentiation in each local resource pool set.
