Innovation Solution
The method and apparatus provide UE information reporting and resource configuration methods for 5G sidelink, including identification information acquisition and reporting, sidelink bearer configuration, priority sorting of logical channels, HARQ process ID management, and PSFCH resource allocation, to optimize communication in V2X scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 5G sidelink communication is implemented for internet of vehicles, then communication performance (data rate, latency, reliability) is improved, but resource allocation and identification management become complex due to lack of standardized schemes
Solution Approach 1:
The patent segments UE information reporting into different types (initial reporting, periodic reporting, aperiodic reporting) and resource configuration into separate procedures (bearer configuration, logical channel priority configuration, HARQ process configuration). This segmentation allows the network to manage complex 5G sidelink resources through modular, standardized reporting mechanisms, improving reliability while maintaining manageable complexity.
Solution Approach 2:
The patent implements preliminary action by requiring UEs to report identification information and capability information before actual data transmission. The network configures bearers, logical channels, and HARQ processes in advance based on UE reports. This preliminary configuration establishes a standardized framework that ensures reliable communication while simplifying real-time resource allocation.
2Measurement precision
If detailed UE information reporting is implemented, then resource allocation accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent applies partial action by implementing selective UE information reporting. UEs report only necessary identification information (Layer 2 ID, Layer 3 ID) and capability information relevant to their specific communication needs. The network requests specific information types based on service requirements, avoiding unnecessary signaling overhead while maintaining sufficient accuracy for resource allocation.
Solution Approach 2:
The patent changes reporting parameters dynamically based on communication scenarios. Different reporting configurations are applied for different service types (e.g., URLLC vs. eMBB), adjusting the level of detail in UE information reports. This parameter adaptation optimizes the balance between allocation accuracy and signaling overhead for different V2X applications.

AI summary
Provided are a user equipment (UE) information reporting method and apparatus, an internet of vehicles resource configuration method and apparatus, and a storage medium. The reporting method includes the following steps: a first UE acquires identification information of a second UE; and the first UE sends identification information of the second UE before an adjustment and identification information of the second UE after the adjustment to a network element device on a network side to report UE information.
