NR Sidelink Capability Allocation for Multi-Mode V2X Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LTE sidelink communication systems lack solutions for capability and resource allocation, particularly for advanced V2X services requiring unicast, multicast, or groupcast, which are supported by the NR system but not adequately addressed in related art.
Innovation Solution
A method and system for terminal devices and control devices to obtain and manage information about maximum processing capabilities and allocable resources, enabling flexible and dynamic allocation for sidelink transmission configurations, including different transmission types, resource pools, services, connection statuses, and transmission modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LTE sidelink communication is used, then basic security communication is supported, but advanced V2X services requiring unicast, multicast, or groupcast are not applicable
Solution Approach 1:
The patent changes the fundamental parameters of sidelink communication by introducing capability negotiation mechanisms and resource allocation frameworks that enable advanced service types (unicast, multicast, groupcast) while maintaining the basic security communication foundation. This allows the system to adapt to different service requirements without requiring complete system redesign.
2Adaptability or versatility
If NR SL system supports establishment of SL connections to multiple peer devices, then comprehensive service types are enabled, but capability and resource allocation solutions are not provided in related art
Solution Approach 1:
The patent segments the resource allocation problem into multiple manageable components by introducing separate mechanisms for capability negotiation, resource pool configuration, and allocation decision-making. This segmentation allows the system to handle multiple peer devices and transmission modes systematically without overwhelming complexity.
Solution Approach 2:
The patent implements dynamic capability negotiation and resource allocation mechanisms that can adapt to changing network conditions and service requirements. The system can dynamically adjust resource allocation based on real-time needs of different peer devices and transmission modes, enabling comprehensive service support without fixed complex infrastructure.
3Productivity
If capability and resource allocation information is obtained and managed, then flexible and dynamic allocation is enabled, but implementation complexity and costs increase
Solution Approach 1:
The patent enables terminal devices to autonomously obtain and manage capability and resource allocation information through self-configuration mechanisms. Devices can independently negotiate capabilities and allocate resources without requiring complex centralized control, thereby achieving efficient resource allocation while reducing overall implementation complexity.
