V2X Device Missed Reservation Metric Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Vehicle-to-Everything (V2X) wireless communication networks, missed reservations for resource allocation lead to inefficiencies and potential collisions, as devices may miss reserved resources due to packet delays or overlapping transmissions, resulting in underutilized resources and increased interference.
Innovation Solution
A wireless communication device calculates a missed reservation metric based on missed reservations and limits additional reservations when this metric exceeds a predefined limit, preventing further missed reservations by prohibiting resource allocation until the metric falls below the threshold, thus optimizing resource usage and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a V2X device reserves multiple resources for transmissions, then the quantity of resource allocations increases, but the number of missed reservations increases leading to resource underutilization and interference
Solution Approach 1:
The patent implements a feedback mechanism where the V2X device monitors its own transmission status and compares expected transmissions against actual transmissions. When a missed reservation is detected (expected transmission not performed), the device provides feedback by updating a missed reservation counter and potentially adjusting future reservation behavior based on the accumulated miss rate, thereby resolving the contradiction between reserving more resources and maintaining reliability
Solution Approach 2:
The patent introduces dynamic adjustment of reservation behavior based on the missed reservation metric. The device adapts its reservation strategy in real-time by comparing the current missed reservation counter against a threshold, dynamically switching between continuing reservations and pausing further reservations to prevent resource underutilization and interference
2Productivity
If the V2X device continues to make reservations despite missed reservations, then resource allocation activity increases, but interference and resource underutilization worsen
Solution Approach 1:
The patent applies preliminary action by establishing a missed reservation counter and threshold before problematic behavior occurs. The device proactively monitors reservation success and preemptively pauses further reservations when the metric indicates potential issues, preventing interference and resource underutilization before they escalate
Solution Approach 2:
The patent implements skipping by temporarily pausing the reservation process when the missed reservation metric exceeds the threshold. The device rushes through the monitoring and detection phase, then skips further reservations until the metric improves, allowing the system to recover from a state of high missed reservations

AI summary
Aspects relate to limiting the number of missed reservations by a wireless communication device, such as a vehicle-to-everything (V2X) device. The wireless communication device may calculate a missed reservation metric associated with one or more missed reservations missed by the wireless communication device. The wireless communication device may then limit additional reservations when the missed reservation metric exceeds a missed reservation limit.
