Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicular communication systems face challenges in efficiently managing radio resources at intersections, where multiple road users need to coordinate their maneuvers, leading to limitations in downlink, uplink, and side-link communication, which can result in insufficient radio resources for reliable communication.
Innovation Solution
A method that predicts the radio resources required for communication among road users at an intersection based on planned maneuvers and environmental perception data, adapting the duplex resource scheme, such as dynamic Time Division Duplex (TDD), to allocate sufficient resources for downlink, uplink, and side-link communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radio resources are allocated statically for downlink, uplink and side-link communication, then the allocation is simple and predictable, but insufficient radio resources are available for reliable communication at intersections with multiple road users
Solution Approach 1:
The patent applies dynamic resource allocation by predicting future communication needs at intersections and adapting the duplex resource scheme in real-time. The system dynamically adjusts radio resource allocation between downlink, uplink and side-link communication based on predicted maneuvers of road users, ensuring sufficient resources are available when needed while maintaining coordination complexity at manageable levels through automated prediction algorithms.
2Reliability
If the duplex resource scheme is adapted to allocate more radio resources for communication, then sufficient resources are available for reliable communication, but the coordination and control complexity increases
Solution Approach 1:
The patent implements preliminary action by predicting future communication requirements at intersections before they occur. The system analyzes planned maneuvers of road users in advance and pre-adjusts the duplex resource scheme to allocate sufficient radio resources beforehand. This predictive approach ensures reliable communication while simplifying real-time coordination, as the resource allocation decisions are made in advance based on predicted behavior rather than reactive control.
3Productivity
If radio resources are allocated dynamically based on real-time communication needs, then sufficient resources are available, but the prediction and control complexity increases
Solution Approach 1:
The patent applies parameter changes by adjusting the duplex resource scheme parameters (time division duplex configuration) based on predicted communication needs. The system changes allocation parameters such as the proportion of resources dedicated to downlink, uplink and side-link communication according to the predicted maneuvers and traffic conditions. This enables efficient resource utilization while keeping the control mechanism relatively simple through standardized parameter adjustment rules.
