UE Capability-Based V2X Policy Provisioning Across E-UTRA and NR
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) may not support both Evolved UMTS Terrestrial Radio Access (E-UTRA) and New Radio (NR) based V2X communication over PC5 and Uu/NG-Uu interfaces, leading to unnecessary provisioning of unsupported policy/parameters and potential communication overload.
Innovation Solution
UE indicates its capability for supporting V2X communication over E-UTRA PC5 or NR PC5 and/or Uu (E-UTRA) or NG-Uu (NR), allowing the V2X Control Function to decide and provision appropriate policy/parameters based on UE capability and subscription information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the V2X Control Function provisions policy/parameters for all possible V2X communication types (E-UTRA PC5, NR PC5, E-UTRA Uu, NR Uu), then the UE receives comprehensive policy coverage, but the UE experiences communication overload and resource waste when it cannot support all types
Solution Approach 1:
The UE performs capability indication beforehand to inform the V2X Control Function about its supported communication types. This preliminary action allows the network to prepare and provision only the appropriate policy/parameters matching the UE's actual capabilities, avoiding the overload of receiving comprehensive policies for unsupported types.
Solution Approach 2:
The V2X Control Function provides different quality levels of policy provisioning based on UE capability. Instead of uniform comprehensive provisioning, the system tailors the policy set to match each UE's specific supported communication types, ensuring optimal resource utilization without over-provisioning.
2Productivity
If the V2X Control Function provisions policy/parameters without considering UE capability, then the provisioning process is simple and fast, but unsupported policy/parameters are wasted resources and may cause communication errors
Solution Approach 1:
The capability indication is performed before the provisioning process, allowing the V2X Control Function to filter and prepare only the necessary policy/parameters in advance. This preliminary filtering maintains fast provisioning speed while eliminating the waste of transmitting and processing unsupported policies.
Solution Approach 2:
The V2X Control Function dynamically adjusts the provisioning parameters based on the UE's capability indication. By changing the set of provisioned policy/parameters to match UE capabilities, the system avoids wasting resources on unsupported types while maintaining efficient provisioning throughput.
3Adaptability or versatility
If the UE supports multiple V2X communication types (E-UTRA and NR based PC5 and Uu), then the UE has high versatility, but the network must manage more complex capability indications and policy provisioning
Solution Approach 1:
The capability indication is segmented into distinct communication types (E-UTRA PC5, NR PC5, E-UTRA Uu, NR Uu), allowing the UE to clearly indicate which specific types it supports. This segmentation simplifies the management complexity by breaking down the multi-type capability into manageable, clearly defined indicators that the V2X Control Function can easily process.
