V2X Terminal Resource Reporting Across PLMNs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially in V2X communication scenarios where a serving cell and a neighbor cell belong to different public land mobile networks (PLMNs), the uplink transmission often has higher priority than V2X communication, leading to performance deterioration of V2X communication due to unknown resource allocation between cells.
Innovation Solution
A method where a terminal acquires and reports resource allocation information related to V2X communication from the neighbor cell to the serving cell, allowing the serving cell to schedule resources effectively and protect V2X communication performance by determining synchronization and resource utilization between cells.

Engineering Contradiction Analysis
1Device complexity
If resource allocation information is not shared between serving cell and neighbor cell, then network complexity is reduced, but V2X communication performance deteriorates due to unknown resource allocation
Solution Approach 1:
The patent introduces an intermediary information exchange mechanism where the terminal acts as a mediator to report neighbor cell V2X resource allocation information to the serving cell. This indirect information sharing through the terminal achieves V2X performance protection without requiring direct complex inter-cell communication infrastructure.
Solution Approach 2:
The patent implements a feedback loop where the terminal detects V2X communication in neighbor cells, reports the resource allocation information back to the serving cell, and the serving cell uses this feedback to adjust scheduling decisions. This feedback mechanism enables performance protection while maintaining relatively simple network architecture.
