V2X Location Reporting Adaptation via Reference Entity Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current V2X communication systems face challenges in efficiently managing location information reporting in E-UTRA networks, particularly in reducing data traffic and interference, especially in scenarios with a large number of vehicles, where explicit geo-location reporting can be cumbersome and resource-intensive.
Innovation Solution
The method involves adapting the mode of location information reporting by suspending explicit geo-location information and using implied location information, such as an identifier associated with a reference radio access network entity, when a reference radio access network entity is detected in the vicinity, thereby reducing data transmission during allocated timeslots and allowing the network to determine the user equipment's location based on the known location of the reference entity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If explicit geo-location information is reported continuously, then location accuracy is improved, but network traffic and interference increase
Solution Approach 1:
The patent extracts only the essential location identification information (reference radio access network entity identifier) from the complete geo-location data when a reference entity is detected. This selective extraction reduces the amount of data transmitted while maintaining sufficient location identification capability for V2X operations.
Solution Approach 2:
The patent applies partial action by reporting only implied location information (reference entity identifier) instead of complete geo-location data when a reference radio access network entity is present. This partial reporting is sufficient for V2X operations and significantly reduces network traffic.

3Quantity of substance
If implied location information is used instead of explicit geo-location, then network traffic is reduced, but location determination complexity increases
Solution Approach 1:
The patent performs preliminary action by pre-configuring the user equipment with information about reference radio access network entities, including their identifiers and locations, before the actual location reporting process. This preparation simplifies the subsequent location determination, as the network element only needs to map the reported reference entity identifier to the pre-known location information.
4Productivity
If location reporting mode is adapted dynamically, then resource efficiency is improved, but control complexity increases
Solution Approach 1:
The patent implements feedback by having the user equipment detect the presence of reference radio access network entities and automatically adjust the location reporting mode based on this detection. The system provides feedback to the network through the reported reference entity identifier, enabling dynamic adaptation of resource usage without requiring complex centralized control.
