Selective ITS Technology Activation for Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The simultaneous deployment of multiple intelligent transport system (ITS) technologies in the same frequency band leads to interference, collisions, and high communication errors, posing safety concerns and inefficient resource utilization.
Innovation Solution
A user equipment (UE) capable of identifying its proximity to areas supporting different ITS technologies selectively enables or disables these technologies based on distance thresholds, avoiding interference by disabling conflicting ITS technologies when within specific areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple ITS technologies are simultaneously deployed in the same frequency band, then device capability and service coverage are improved, but interference and communication errors increase
Solution Approach 1:
The patent applies local quality by enabling the UE to dynamically adjust ITS technology activation based on geographic location. The system determines the UE's position relative to geo-fenced areas and selectively activates or deactivates specific ITS technologies (e.g., C-V2X, ITS-G5) depending on which technology is appropriate for the current location, thereby maintaining high adaptability while avoiding interference in specific regions.
Solution Approach 2:
The patent implements dynamics by making the ITS technology configuration changeable in real-time based on UE movement and location. The system continuously monitors UE position and dynamically switches between different ITS technology modes, allowing the device to adapt its capabilities according to the current geographic context rather than using a fixed configuration.
2Adaptability or versatility
If multiple ITS technologies are simultaneously deployed in the same frequency band, then service coverage is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent applies local quality by tailoring the active ITS technologies to match the specific requirements of each geographic area. By activating only the necessary technologies in each location rather than all available technologies simultaneously, the system maintains comprehensive service coverage while optimizing resource utilization and reducing energy consumption in each local context.
3Reliability
If the UE disables conflicting ITS technologies based on location, then interference is reduced, but device complexity increases
Solution Approach 1:
The patent applies self-service by enabling the UE to autonomously determine its location, identify appropriate ITS technologies for the current area, and activate or deactivate technologies without manual intervention. The system automatically manages the complexity of multi-technology coordination by implementing location-based decision logic that handles technology selection and switching independently.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify that the UE is within a distance threshold of an area that supports a first intelligent transport system (ITS) technology, wherein the UE has a capability to support a second ITS technology different from the first ITS technology. The UE may disable the second ITS technology based at least in part on identifying that the UE is within the distance threshold of the area. Numerous other aspects are described.
