Dynamic Radio Resource Arbitrator for V2X Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for allocating radio resources in V2X communication, particularly in shared frequency bands among multiple PLMNs, suffer from inefficiency due to fixed allocation strategies that lead to congestion in some networks while others have excess resources, especially in dynamic traffic scenarios.
Innovation Solution
A method that estimates radio resource requirements based on measurement of usage in preceding zones and time windows, using a resource arbitrator to dynamically allocate resources across PLMNs, considering traffic flow, vehicle movement, and other data sources to predict future resource needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If fixed allocation strategies are used for radio resources in shared frequency bands, then resource allocation is simple to implement, but congestion occurs in some networks while others have excess resources
Solution Approach 1:
The patent implements dynamic resource allocation by continuously monitoring radio resource usage in the first geographic region and adjusting allocations based on measured utilization patterns. The system transitions from static fixed allocation to dynamic allocation that adapts to changing traffic conditions, ensuring resources are allocated according to actual demand rather than predetermined fixed assignments.
Solution Approach 2:
The patent employs feedback mechanisms by measuring radio resource utilization in the first geographic region and using this information to determine allocations for the second geographic region. The system continuously monitors usage patterns and adjusts resource distribution based on this feedback, creating a closed-loop control system that optimizes utilization efficiency.
2Productivity
If dynamic resource allocation is implemented across multiple PLMNs, then resource utilization efficiency improves, but system complexity increases
Solution Approach 1:
The patent introduces a resource allocation mechanism that acts as an intermediary between multiple PLMNs sharing the frequency band. This intermediary system monitors usage across different networks and coordinates resource distribution, simplifying the complexity by centralizing the decision-making process rather than requiring each PLMN to independently manage allocations.
Solution Approach 2:
The patent creates a universal resource allocation system that serves multiple PLMNs simultaneously through a shared frequency band. The same monitoring and allocation mechanisms are applied across different networks, providing a multi-functional solution that handles resource distribution for various operators using a unified approach rather than separate systems.
3Measurement precision
If resource allocation is based on historical data from preceding zones, then prediction accuracy improves, but response time to changing conditions increases
Solution Approach 1:
The patent performs preliminary resource allocation by measuring usage in the first geographic region before traffic actually arrives in the second geographic region. By proactively allocating resources based on upstream measurements and movement information, the system prepares resource distributions in advance, reducing response time when traffic conditions change while maintaining prediction accuracy through historical data.
Solution Approach 2:
The patent implements dynamic adjustments to resource allocation by continuously monitoring usage patterns and adapting allocations to changing traffic conditions. The system balances the use of historical data with real-time measurements, allowing it to maintain prediction accuracy while responding promptly to changing traffic demands through continuous optimization.

AI summary
Computer-readable media, methods and apparatus for allocating radio resources for a geographic region are disclosed. In some aspects, the apparatus may be an arrangement including a determiner that determines first radio resource utilization information for a first duration of a first geographic region. The arrangement may also include an estimator that estimates second radio resource utilization information for a second duration of a second geographic region, based on the first radio resource utilization information and based on movement information about a plurality of communication terminals that affected the first radio resource utilization information in the first geographic region. The arrangement may further include an allocator that allocates radio resources for the second geographic region based on the estimation of the second radio resource utilization information. The first duration may precede the second duration, and the first geographic region may neighbor the second geographic region.
