Pedestrian UE Authorization in V2X Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in authorizing pedestrian user equipment (UE) in vehicle-to-everything (V2X) communications, particularly in ensuring proper authentication and radio resource allocation for pedestrian UEs, which is crucial for safe and efficient V2X services.
Innovation Solution
The method involves an eNodeB (eNB) receiving authorization information for pedestrian UE, vehicle UE, and roadside unit (RSU) UE, using specific information elements (IEs) to determine authorization status and manage radio resources effectively, including partial sensing in sidelink transmission to conserve power for pedestrian UEs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authorization information is received and processed for pedestrian UE in V2X communication, then authentication reliability is improved, but system complexity increases
Solution Approach 1:
The authorization information is segmented into distinct information elements (IEs), where each IE represents a specific authorization status for different UE types (pedestrian UE, vehicle UE, RSU UE). This segmentation allows the eNB to process and authorize different UE types independently, improving authentication reliability while managing system complexity through modular information handling.
2Adaptability or versatility
If radio resources are allocated for pedestrian UE in V2X communication, then service availability is improved, but resource management complexity increases
Solution Approach 1:
The patent applies local quality by providing differentiated radio resource allocation and authorization based on UE type. Pedestrian UEs receive specific authorization and resource allocation tailored to their V2X communication needs, while vehicle UEs and RSU UEs receive different configurations. This targeted approach improves service availability for each UE type without requiring complex global resource management for all UEs uniformly.

AI summary
For vehicle-to-everything (V2X) communication, an eNodeB (eNB) receives authorization information for a pedestrian UE which indicates whether a user equipment (UE) is authorized as the pedestrian UE. Upon receiving the authorization information for the pedestrian UE, the eNB may authorize the UE as the pedestrian UE or not according to the received authorization information, and decide a resource allocation mode for the authorized pedestrian UE.
