V2X Object Messaging for Driving Path Change Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in accurately and efficiently transmitting and receiving messages in vehicle-to-everything (V2X) scenarios, particularly in scenarios involving mobility changes and potential driving obstructions, which affect the reliability and latency of vehicle communications.
Innovation Solution
A method for transmitting messages in a wireless communication system that includes detecting objects with mobility changes greater than a specific threshold and incorporating object information for both the primary and secondary objects, even if the secondary object's mobility change is below the threshold, along with driving obstruction information, to enhance message accuracy and efficiency.

Engineering Contradiction Analysis
1Productivity
If object information is transmitted only for objects with mobility change greater than threshold, then message size is reduced and transmission efficiency is improved, but message accuracy is degraded by omitting secondary objects that may cause driving obstructions
Solution Approach 1:
The patent applies local quality by differentiating the treatment of objects based on their relationship to the first object. Objects are categorized into those that require full information transmission (second objects with high probability of causing driving path changes) and those that can use threshold-based filtering (other objects). This selective application of information inclusion criteria ensures message accuracy for critical objects while maintaining transmission efficiency for non-critical objects.
Solution Approach 2:
The patent performs preliminary action by calculating the probability that a second object will cause the first object to change its driving path before determining whether to include the second object's information in the message. This pre-assessment allows the system to proactively include necessary object information even when mobility change thresholds are not met, ensuring that critical obstruction information is not omitted while avoiding unnecessary data transmission.
2Reliability
If object information for second object is included based on driving path change probability, then reliability of vehicle communication is improved, but message size increases
Solution Approach 1:
The patent changes the parameter used for object selection from solely mobility change magnitude to a probability-based criterion (likelihood of causing driving path changes). This parameter transformation allows the system to identify and include critical objects that may not exhibit large mobility changes but pose significant obstruction risks, thereby improving communication reliability without indiscriminately increasing message size for all objects.
Solution Approach 2:
The patent applies partial action by selectively including second object information only when the calculated probability of driving path change exceeds a specific threshold. This selective inclusion ensures that reliability is improved for critical scenarios while avoiding unnecessary message size increases for objects that do not pose significant obstruction risks, achieving a balanced approach between reliability and message compactness.

AI summary
Disclosed are a method in which a network transmits a message in a wireless communication system, and an apparatus therefor, according to various embodiments. Disclosed are a method and an apparatus therefor, the method comprising the steps of: detecting multiple objects including a first object and a second object; determining, among the multiple objects, at least one object having a change in object mobility equal to or greater than a specific threshold; and transmitting a message including object information for the at least one object including the first object, wherein, on the basis that a probability by which the first object changes a driving path due to the second object is equal to or greater than a specific threshold probability, the message further comprises object information about the second object even if a change in the mobility of the second object is less than the specific threshold.
