Sidelink Parameter Configuration for V2X UE-UE Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of Vehicle to Everything (V2X) in 5G New Radio (NR) systems, there is a lack of effective solutions for User Equipment (UE) to UE control, including triggering capability interaction, determining control granularity, and handling abnormal situations.
Innovation Solution
A parameter configuration method is introduced where terminal devices exchange parameter combinations via higher layer signaling or RRC signaling to indicate sidelink data sending and receiving parameters, enabling UE-UE control and mutual configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If traditional network-controlled methods are used for V2X communication, then centralized control and management are achieved, but terminal device autonomy and direct UE-UE control capability are insufficient
Solution Approach 1:
The patent enables terminal devices to autonomously determine and exchange parameter combinations without network intervention. Each UE independently selects parameters from pre-configured sets and directly communicates them to other UEs, allowing the system to serve itself rather than relying on centralized network control for parameter configuration.
Solution Approach 2:
The patent divides the control function into separate components: the network provides pre-configured parameter sets, while individual UEs autonomously select and exchange specific parameter combinations. This segmentation allows UE-UE control autonomy while keeping the overall system manageable through modular parameter sets.
2Reliability
If comprehensive parameter configuration is implemented for UE-UE control, then communication reliability is improved, but signaling overhead and configuration complexity increase
Solution Approach 1:
The patent implements partial parameter configuration where UEs exchange only the necessary parameter combinations for their specific communication needs rather than all possible parameters. This partial action approach ensures sufficient communication reliability while minimizing signaling overhead by transmitting only relevant parameter sets.
Solution Approach 2:
The patent uses pre-configured parameter sets that can be selectively activated and exchanged. By changing between predefined parameter combinations rather than configuring individual parameters dynamically, the system achieves reliable communication adaptability while reducing the complexity and overhead of parameter management.
3Adaptability or versatility
If dynamic parameter exchange is enabled between terminal devices, then communication adaptability is improved, but system complexity and coordination difficulty increase
Solution Approach 1:
The patent performs preliminary configuration by pre-defining multiple parameter combinations before actual communication occurs. The network provides these pre-configured sets to UEs in advance, so that during dynamic communication, UEs only need to exchange references to these pre-established parameter sets rather than negotiating individual parameters, thereby reducing real-time complexity while maintaining adaptability.
Solution Approach 2:
The patent creates universal parameter sets that can be applied across different UE pairs and communication scenarios. These multi-functional parameter combinations can serve multiple purposes and different communication conditions, reducing the total number of parameter sets needed while maintaining system adaptability to various communication requirements.
