Out-of-Coverage UE Resource Configuration via Intermediary Carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In PC5-based V2X communication, user equipment (UE) out of coverage on an operating carrier/frequency cannot update resource configurations, leading to inflexibility in resource allocation, particularly in scenarios without a deployed base station.
Innovation Solution
A method and apparatus that allow a UE out of coverage on an operating carrier/frequency to obtain resource configuration information from a configuration carrier/frequency where it is in coverage, enabling flexible resource configuration and updates by determining a configuration carrier/frequency and obtaining resource configuration information via broadcast messages or dedicated signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UE out of coverage on operating carrier/frequency uses preconfigured resources for communication, then communication can be established without base station, but resource configuration cannot be updated leading to inflexibility
Solution Approach 1:
The patent introduces a configuration carrier/frequency as an intermediary that carries resource configuration information for the operating carrier/frequency. When UE is out of coverage on the operating carrier, it can still obtain updated resource configuration information by monitoring the configuration carrier where it remains in coverage, thus resolving the contradiction between maintaining communication and enabling flexible resource updates.
2Adaptability or versatility
If UE determines it is out of coverage on operating carrier/frequency, then it can communicate on preconfigured resource, but the preconfigured resource cannot be modified according to service characteristics
Solution Approach 1:
The patent segments the resource configuration management into two parts: preconfigured resources for basic communication and configurable resources on the configuration carrier for service-specific optimization. This allows UE to use simple preconfigured resources when needed while enabling access to updated, service-specific configurations when available, resolving the contradiction between simplicity and adaptability.
3Ease of manufacture
If no base station is deployed on operating carrier/frequency for PC5-based V2X, then deployment is feasible in high frequency band, but resource configuration cannot be updated dynamically
Solution Approach 1:
The patent uses a configuration carrier/frequency as a mediator that allows base station to provide resource configuration information indirectly to UE on the operating carrier/frequency where no base station is deployed. This enables dynamic resource configuration updates without requiring physical base station deployment on the high frequency band operating carrier.
