V2X Resource Recommendation via Third-Party Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing resource allocation for vehicle-to-everything (V2X) communication, particularly in next-generation wireless access technologies like new radio (NR), where traditional resource allocation methods may not be suitable for the evolving network architecture and increased communication demands.
Innovation Solution
A method for a terminal to receive recommendation information for available resources from a third terminal and perform V2X communication using either the recommended resource or a resource selected based on this information, allowing for more efficient use of resource pools and adaptive resource management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional resource allocation methods are used in V2X communication, then device complexity is reduced, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent introduces a third terminal as an intermediary that recommends resources between the first and second terminals. This mediator collects resource pool information, determines recommended resources based on channel conditions and interference levels, and provides recommendations to the communicating terminals, thereby improving resource utilization without significantly increasing terminal complexity
Solution Approach 2:
The third terminal performs preliminary resource assessment and recommendation before the actual V2X communication occurs. By pre-analyzing resource pool conditions and providing recommended resources in advance, the system avoids complex real-time resource allocation decisions during communication, improving efficiency while maintaining manageable complexity
2Reliability
If autonomous resource selection is implemented, then communication reliability is improved, but loss of time increases due to sensing and selection processes
Solution Approach 1:
The third terminal performs resource assessment and generates recommendations in advance of the actual communication need. This preliminary action allows the first terminal to skip extensive sensing and selection processes, reducing the time lost while still achieving reliable resource selection based on pre-analyzed channel conditions
Solution Approach 2:
The system implements feedback mechanisms where the third terminal continuously monitors resource pool conditions and provides updated recommendations. This feedback loop ensures that terminals receive current resource status information, improving communication reliability without requiring terminals to perform time-consuming autonomous sensing and selection

AI summary
In a wireless communication system, a third party different from both terminals or a base station, which are parties to vehicle-to-everything (V2X) communication, may be involved in resource allocation for the V2X communication. For example, a first terminal performing V2X communication with a second terminal receives recommendation information recommending a resource available for the V2X communication from a third terminal and performs the V2X communication with the second terminal by using a recommended resource determined based on the recommendation information or a resource selected by the first terminal based on the recommendation information.
