UE Sidelink Message Transmission Control via Vehicle Boarding Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, there is a need to minimize unnecessary transmission of safety messages by user equipment (UE) to prevent increased communication traffic and power consumption, especially when a vehicle is boarded, which can lead to unnecessary message transmission.
Innovation Solution
A method and device for a UE to measure position information and receive messages with specific area information, estimating whether a vehicle is boarded based on the reception strength and stopping the transmission of safety messages accordingly, considering factors like beacon ID and movement detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UE continuously transmits safety messages to ensure safety monitoring, then the safety monitoring reliability is improved, but the communication traffic and power consumption increase
Solution Approach 1:
The patent implements dynamic transmission control by switching between VRU mode (continuous transmission) and vehicle mode (discontinuous transmission) based on real-time boarding detection. The UE dynamically adjusts its transmission behavior by monitoring beacon signals and position information, stopping transmission when boarded and resuming when unboarded, thereby optimizing power consumption while maintaining safety monitoring reliability.
Solution Approach 2:
The system uses feedback mechanisms by continuously monitoring beacon ID, reception strength, and position information to determine boarding state. This feedback loop enables the UE to automatically adjust transmission behavior based on whether it is inside or outside the vehicle, resolving the contradiction between continuous transmission for safety and power conservation.

3Reliability
If the UE transmits safety messages when boarded to maintain safety monitoring, then the safety monitoring coverage is improved, but unnecessary message transmission occurs
Solution Approach 1:
The patent extracts the transmission control logic based on boarding state detection. By separating the transmission behavior into two distinct modes (VRU mode for unboarded state and vehicle mode for boarded state), the system eliminates unnecessary transmissions during boarding while maintaining safety monitoring coverage when unboarded, using beacon monitoring and position information as the extraction criterion.

AI summary
The Disclosed are a method for a UE to transmit a first message in a wireless communication system supporting sidelink, and a device for same according to various embodiments. The method for transmitting a first message includes the steps of: measuring location information pertaining to the UE and transmitting the first message; receiving a second message; and determining whether to stop the transmission of the first message on the basis of the location information and the second message, wherein, when information about a specific area is included in the second message that is received with a reception strength equal to or greater than a first reference threshold, the UE estimates whether a vehicle is occupied on the basis of the acquired specific area and the location information, and stops the transmission of the first message on the basis of the estimation of vehicle occupancy.
