Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently managing and prioritizing vehicle-to-everything (V2X) messages based on reception and transmission priorities, particularly in next-generation radio access technologies like NR, which are essential for reliable and low-latency communications in scenarios such as vehicle platooning, advanced driving, and remote driving.
Innovation Solution
A method and device for operating multiple queues based on reception and transmission priorities, selecting and filtering messages using zone identifiers, and prioritizing their transmission in wireless communication systems, specifically for V2N services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all V2N messages are transmitted without filtering, then message delivery completeness is improved, but communication resource efficiency deteriorates due to unnecessary data handling
Solution Approach 1:
The patent extracts and removes unnecessary V2N messages from the transmission stream by filtering messages based on reception priority and transmission priority. The base station identifies and eliminates redundant messages before transmission, reducing communication resource consumption while maintaining delivery of essential messages.
Solution Approach 2:
The patent performs preliminary filtering and prioritization of V2N messages before transmission. The base station pre-processes messages by determining reception priority and transmission priority, and selectively filters messages in advance, so that only necessary messages are transmitted to user equipment.
2Measurement precision
If multiple queues are operated based on reception and transmission priorities, then message prioritization accuracy is improved, but device complexity increases
Solution Approach 1:
The patent segments the message processing system into multiple queues based on reception priority and transmission priority. Messages are divided into different priority levels and processed in separate queues, enabling accurate prioritization while organizing the complexity into manageable segments.
Solution Approach 2:
The patent applies different quality levels of processing to different messages based on their priority. High-priority messages receive more thorough processing and are placed in dedicated queues, while lower-priority messages receive standard processing. This local differentiation improves prioritization accuracy without uniformly increasing device complexity.
3Loss of energy
If zone identifiers are used for message filtering, then communication resource efficiency is improved, but measurement precision requirements increase
Solution Approach 1:
The patent extracts zone identifier information from V2N messages and uses it to filter messages at the base station. By extracting and utilizing the zone identifier, the system efficiently filters out messages not relevant to specific user equipment, reducing communication resource consumption.
