V2X Blind Retransmission Control via Distance Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing V2X communication technologies do not effectively limit blind retransmissions, leading to excessive signaling overhead and impacting communication reliability.
Innovation Solution
A data transmission method that triggers blind retransmissions based on communication distance thresholds and limits retransmissions by updating and checking against preset retransmission time thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blind retransmission mechanism is triggered to ensure communication quality, then communication reliability is improved, but signaling overhead increases excessively
Solution Approach 1:
The patent changes the parameter of retransmission timing by introducing a blind retransmission mechanism triggered by specific conditions (e.g., distance thresholds, channel quality indicators). This allows the system to adapt retransmission behavior dynamically, improving reliability only when necessary and thereby controlling signaling overhead.
Solution Approach 2:
The patent implements a dynamic retransmission strategy where the transmitting terminal decides whether to perform blind retransmission based on real-time channel conditions and preconfigured thresholds. This dynamic approach prevents excessive retransmissions in good channel conditions while ensuring reliability when channel quality degrades, thus balancing reliability improvement with overhead control.
2Reliability
If unlimited blind retransmission is performed to ensure communication quality, then communication reliability improves, but resource waste increases
Solution Approach 1:
The patent applies preliminary action by preconfiguring retransmission parameters (maximum retransmission count, distance thresholds, channel quality thresholds) before actual communication occurs. This allows the system to have predefined boundaries for blind retransmission, ensuring that reliability is improved within controlled resource limits without requiring complex real-time decisions.
Solution Approach 2:
The patent incorporates feedback mechanisms where the transmitting terminal monitors channel conditions and communication outcomes to decide whether to initiate blind retransmission. This feedback-driven approach ensures that retransmissions are performed only when genuinely needed, improving reliability while avoiding unnecessary resource consumption from excessive retransmissions.

AI summary
A data transmission method and device and a storage medium. The method comprises: in the process of triggering a blind retransmission mechanism, regularly acquiring the number of retransmission times (101); and when the number of retransmission times is less than a preset threshold number of retransmission times, retransmitting data to a receiving terminal, and updating the number of retransmission times (102).
