V2V Message Transmission Using Priority Resource Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of Vehicle-to-Vehicle (V2V) communication, existing message transmission solutions fail to ensure timely and reliable delivery of critical data, such as speed, position, and direction, especially during sudden events like accidents or congestion, due to high time requirements and complex application scenarios.
Innovation Solution
A method that determines the use of first priority resource blocks for transmitting core message packets, with a shorter time interval between these blocks compared to other priority blocks, ensuring frequent and reliable transmission of critical data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If message packets are transmitted using standard resource blocks with uniform time intervals, then resource allocation is simple and uniform, but transmission timeliness and reliability cannot be ensured for critical V2V events
Solution Approach 1:
The patent applies local quality by differentiating resource block allocation based on message priority. High-priority V2V messages are allocated specific resource blocks with shorter time intervals, while low-priority messages use standard resource blocks. This creates localized quality improvements in critical transmission paths without complicating the entire resource allocation system.
Solution Approach 2:
The patent segments message packets into high-priority and low-priority portions, allocating them to different resource blocks with different time intervals. This segmentation allows critical safety-related data to be transmitted more frequently and reliably, while non-critical data uses standard allocation, resolving the contradiction between reliability and complexity.
2Loss of time
If the time interval between resource blocks is reduced to ensure timely transmission of critical data, then transmission timeliness improves, but resource consumption increases
Solution Approach 1:
The patent applies local quality by reducing time intervals only for high-priority resource blocks that carry critical V2V messages, while maintaining standard time intervals for low-priority messages. This localized optimization reduces transmission delay where needed without proportionally increasing overall resource consumption across all message types.
Solution Approach 2:
The patent segments resource allocation into high-priority and low-priority resource blocks with different time intervals. Critical safety data uses frequent transmission with shorter intervals, while non-critical data uses standard intervals, thereby reducing overall resource consumption compared to uniformly high-frequency transmission.
3Reliability
If all message packets are transmitted with high priority to ensure reliability, then transmission reliability improves, but system efficiency and resource utilization deteriorate
Solution Approach 1:
The patent applies local quality by providing high-reliability transmission resources only to high-priority V2V messages that require it, such as safety-critical data. Low-priority messages use standard resource allocation, maintaining overall system efficiency while ensuring reliability where needed.
Solution Approach 2:
The patent segments messages into priority levels and allocates resources accordingly. High-priority messages receive dedicated resource blocks with higher reliability guarantees, while low-priority messages share standard resources, thereby maintaining system efficiency while ensuring reliability for critical communications.
Data Source
AI summary
A message transmitting method, a message receiving method and apparatuses are provided. A method comprises: according to the size of a message packet to be transmitted, determining a resource used for transmitting the message packet, wherein the resource at least comprises a first priority resource block, and the time interval between respective first priority resource blocks is smaller than that between other priority resource blocks, and transmitting at least a first priority part of the message packet by using the at least one first priority resource block. A relatively frequent resource can be used to transmit a core part of a (vehicle to vehicle) V2V message packet, thus ensuring transmission timeliness and reliability of the V2V message.
