V2V Communication Resource Allocation for Seamless Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current resource allocation mechanisms for vehicle-to-vehicle (V2V) communication, especially in platooning scenarios, are not sufficiently accurate and quick, leading to potential communication disruptions and safety risks when vehicles transition between base station coverage areas.
Innovation Solution
A method that involves requesting and reserving specific transmission resources from a second base station entity before leaving the first coverage area, ensuring continuity of V2V communication by allocating identical transmission resources in both coverage areas, thereby minimizing handover delays and ensuring seamless communication within a platoon.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If resource allocation mechanisms are used for V2V communication in platooning scenarios, then transmission resources can be managed, but the allocation is not sufficiently accurate and quick, leading to communication disruptions during handovers
Solution Approach 1:
The patent applies preliminary action by having the UE request and receive allocation acknowledgement for transmission resources in the target cell before actually leaving the source cell coverage area. The allocation request is sent in advance, and the handover is only executed after receiving confirmation that resources are reserved in the target cell, thereby eliminating handover delays and ensuring continuous V2V communication without interruption.
2Productivity
If transmission resources are allocated by base station entities, then resource usage can be controlled, but communication disruptions occur when vehicles transition between coverage areas
Solution Approach 1:
The patent implements feedback by requiring the target base station entity to send an allocation acknowledgement message back to the UE confirming that transmission resources have been successfully reserved. This feedback mechanism ensures that the UE only performs handover when resources are guaranteed in the target cell, preventing communication disruptions and ensuring continuous V2V communication while maintaining efficient resource control.
3Ease of operation
If resource allocation is controlled within each base station coverage area, then local resource management is possible, but handover between coverage areas causes communication interruptions
Solution Approach 1:
The patent applies preliminary action by performing resource allocation in the target cell before handover execution. The UE requests resources from the target base station while still in the source cell coverage, receives allocation acknowledgement confirming resource reservation, and only then executes handover. This approach maintains simple local resource management while eliminating handover execution time delays.
