Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy implementations of wireless communication systems statically split time resources between LTE C-V2X and ITS-G5/DSRC, leading to inefficiencies due to dynamic variations in market penetration and technology adoption rates, without existing communication means to adapt resource allocation dynamically.
Innovation Solution
An electronic device with radio front end and processor circuitry monitors channel occupancy levels to dynamically adjust the resource share between LTE C-V2X and ITS-G5/DSRC by reallocating time slots based on observed channel usage, allowing for adaptive resource allocation based on market penetration and current demand.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If time resources are statically split between LTE C-V2X and ITS-G5/DSRC, then resource allocation is simple and stable, but resource usage efficiency deteriorates due to dynamic variations in market penetration and technology adoption rates
Solution Approach 1:
The patent implements dynamic resource allocation by continuously monitoring channel occupancy levels and adjusting the time resource split between LTE C-V2X and ITS-G5/DSRC accordingly. The system transitions from a static predetermined split to a dynamic adjustment mechanism where resource allocation changes based on real-time channel conditions and technology adoption rates, thereby improving resource usage efficiency while adapting to market variations.
Solution Approach 2:
The patent employs feedback mechanisms where the system monitors channel occupancy levels for both LTE C-V2X and ITS-G5/DSRC technologies and uses this information to adjust resource allocation. The feedback loop continuously evaluates the performance and occupancy of each technology and dynamically modifies the time resource split to optimize overall system efficiency, resolving the contradiction between simplicity and efficiency.
2Productivity
If time resources are dynamically adjusted based on channel occupancy, then resource usage efficiency is improved, but system complexity increases due to monitoring and adjustment mechanisms
Solution Approach 1:
The system implements feedback control by monitoring channel occupancy levels of both LTE C-V2X and ITS-G5/DSRC technologies and using this information to dynamically adjust resource allocation. The feedback mechanism compares actual occupancy against target occupancy levels and automatically adjusts the time resource split accordingly, improving overall system efficiency while maintaining manageable complexity through automated control.
Solution Approach 2:
The resource allocation system operates autonomously by self-monitoring channel occupancy levels and self-adjusting the time resource split between technologies without requiring external intervention. This self-service capability allows the system to adapt to changing conditions automatically, improving efficiency while minimizing the operational complexity for network operators.
3Adaptability or versatility
If a fixed resource split is used, then implementation is simple, but adaptability to market penetration variations deteriorates
Solution Approach 1:
The patent transforms the static resource allocation into a dynamic system that automatically adapts to market penetration variations. By continuously monitoring channel occupancy levels and adjusting the time resource split between LTE C-V2X and ITS-G5/DSRC, the system becomes versatile and adaptable to different technology adoption rates, eliminating the rigidity of fixed allocations while managing complexity through systematic monitoring and adjustment protocols.
Solution Approach 2:
The system changes the resource allocation parameters dynamically based on observed channel occupancy and technology adoption patterns. Instead of maintaining a fixed resource split, the patent adjusts the time resource allocation parameters in response to varying market conditions, thereby achieving adaptability to technology adoption while using structured parameter modification to control implementation complexity.

AI summary
Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for balancing time resource allocation between cellular vehicle-to-everything (C-V2X) and intelligent transport systems (ITSG5)/dedicated short range communication (DSRC). For example, some embodiments are directed to an electronic device including radio front end circuitry and processor circuitry coupled to the radio front end circuitry. The processor circuitry can be configured to monitor, using the radio front end circuitry, a channel for a time period and determine, based on the monitoring the channel, an average channel occupancy level (COL) of the channel over the time period. The processor circuitry can further be configured to compare the average COL to one or more thresholds and change a resource share of long-term evolution (LTE) cellular vehicle-to-everything (C-V2X) intervals based on the comparison.
