V2X Resource Pool Configuration for Traffic-Aware Packet Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current V2X resource pool configurations in 5G New Radio (NR) are inefficient due to static allocation, leading to over-provisioning or under-provisioning of resources based on uniform traffic assumptions, resulting in resource waste and increased collision rates, and require vehicles to monitor unnecessary packets, causing receiver overload and energy inefficiency.
Innovation Solution
A dynamic resource pool configuration system where a V2X control device coordinates with a network device to determine resource pools based on traffic conditions and vehicle attributes, such as road type, direction, and time, allowing vehicles to selectively monitor and use relevant resource pools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If static resource pool allocation is used, then resource configuration is simple, but resource utilization efficiency deteriorates due to over-provisioning or under-provisioning
Solution Approach 1:
The patent implements dynamic resource pool configuration by determining resource pools based on traffic conditions, vehicle attributes (road type, direction, time), and device characteristics. The network device dynamically determines which resource pools to configure for each terminal device based on real-time conditions, replacing static allocation with adaptive, condition-based configuration that optimizes resource utilization while maintaining manageable complexity through automated decision-making.
2Ease of manufacture
If uniform traffic assumptions are used for resource allocation, then allocation process is simple, but resource waste increases and collision rates increase
Solution Approach 1:
The patent applies local quality by tailoring resource pool configurations to specific local conditions including traffic conditions, road types, directions, and time periods. Instead of uniform allocation, the system determines resource pools based on the specific local context of each terminal device, enabling optimized resource distribution that reduces waste and collisions while maintaining simplicity through automated local condition assessment.
3Reliability
If vehicles monitor all resource pools, then packet reception coverage is complete, but receiver overload occurs and energy consumption increases
Solution Approach 1:
The patent extracts and filters only the necessary resource pools for each terminal device based on traffic conditions, vehicle attributes, and device characteristics. The network device determines and configures only the relevant resource pools that each terminal needs to monitor, extracting the essential information while excluding unnecessary resource pools, thereby reducing energy consumption and receiver overload while maintaining reliable packet reception for relevant communications.

AI summary
Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of resource pool configuration and usage for V2X. The method comprises receiving, at a first device, information of a set of resource pools allocated for a predetermined area from a second device and a usage pattern for the set of resource pools from a third device, the usage pattern at least indicating an association between the set of resource pools and at least one property of the predetermined area. The method further comprises determining at least one attribute of the first device related to the at least one property and determining a target resource pool for communication from the set of resource pools based on the at least one attribute, the information and the usage pattern. In the solution, the V2X control device may coordinate the resource pool configuration with the network device and determine polices for the usage of the resource pool. In this way, the resource pool can be configured more efficient for V2X packet distribution and reception.
