Vehicle Boundary Determination via Positioning Reference Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in accurately determining the boundary of vehicles in vehicle-to-vehicle (V2V) and vehicle-to-everything (V2X) communications, which increases the likelihood of collisions due to the small size of communication devices relative to the vehicles.
Innovation Solution
Transmitting a positioning reference signal (PRS) and an information element associated with the vehicle's boundary, including reference position, antenna location, size, attitude, or type, to enable accurate determination of vehicle boundaries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If communication devices are made small for portability, then ease of operation is improved, but the ability to accurately determine vehicle boundaries deteriorates
Solution Approach 1:
The patent introduces positioning reference signals (PRS) and information elements as intermediaries between the small communication device and the large vehicle boundary. These signals carry positioning information that enables the device to accurately determine vehicle boundaries despite its small size, effectively mediating the measurement capability gap between device scale and vehicle scale
Solution Approach 2:
The patent transitions from physical dimension (device size) to information dimension (positioning data). Instead of relying on the physical size of the communication device to determine boundaries, the system uses positioning reference signals and information elements that contain boundary information, changing the problem from a physical measurement issue to an information processing issue
2Measurement precision
If positioning reference signals and boundary information are transmitted, then vehicle boundary determination accuracy is improved, but communication data volume increases
Solution Approach 1:
The patent extracts only the essential boundary information needed for collision avoidance from the complete positioning data set. By transmitting selective information elements (such as relative position, distance, and boundary coordinates) rather than full vehicle telemetry data, the system achieves accurate boundary determination while minimizing communication overhead
Solution Approach 2:
The patent changes the parameter representation from detailed continuous vehicle state data to discrete boundary-defining parameters. By transmitting key parameters such as relative position offsets, distance metrics, and boundary coordinates rather than full vehicle models, the system reduces data volume while maintaining boundary determination accuracy

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter user equipment (UE) may transmit, to a receiver UE, a first communication that includes a positioning reference signal (PRS) associated with the transmitter UE. The UE may transmit, to the receiver UE, a second communication that includes an information element associated with a boundary of a vehicle associated with the transmitter UE. Numerous other aspects are described.
