Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems for vehicular communication face challenges in efficiently managing radio resources, particularly in predicting and allocating resources for localized communication scenarios, which can lead to insufficient radio resources during peak usage.
Innovation Solution
The method involves obtaining environmental perception data from road users and infrastructure to predict the required radio resources for communication, allowing for the dynamic adjustment of duplex resource schemes, such as dynamic Time Division Duplex (TDD), Frequency-division Duplex (FDD), Code Duplex, and Spatial Duplex, to allocate sufficient resources for uplink, downlink, and side-link communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static resource allocation is used in wireless communication systems, then system complexity is reduced, but radio resources are insufficient during peak usage periods
Solution Approach 1:
The patent implements dynamic resource allocation where the duplex resource scheme is adapted in real-time based on predicted communication requirements. The system dynamically adjusts the allocation of uplink, downlink, and side-link resources according to environmental perception data and predicted traffic patterns, transforming the static resource allocation into a dynamic system that responds to changing conditions.
Solution Approach 2:
The system performs preliminary prediction of communication requirements by analyzing environmental perception data before actual communication occurs. This advance prediction allows the system to pre-allocate radio resources according to forecasted needs, ensuring resources are available during peak usage without requiring complex real-time arbitration.
2Adaptability or versatility
If dynamic resource allocation is implemented, then radio resource availability is improved, but system complexity increases
Solution Approach 1:
The patent introduces an intermediary prediction mechanism that sits between environmental perception data and resource allocation decisions. This intermediary layer processes environmental data to predict communication requirements, thereby simplifying the overall system architecture by separating the complex prediction function from the resource allocation function.
Solution Approach 2:
The system uses environmental perception data generated by road users themselves to predict their own communication requirements. Each road user's environmental perception data serves the purpose of predicting resources needed for that user's communication, eliminating the need for external complex monitoring and allocation systems.
3Measurement precision
If environmental perception data is processed, then prediction accuracy is improved, but processing time increases
Solution Approach 1:
The patent extracts only the essential features from environmental perception data that are relevant for predicting communication requirements. Instead of processing complete environmental datasets, the system identifies and processes only the critical elements needed for prediction, thereby maintaining high accuracy while reducing processing time.
