Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently implementing V2X communication, particularly in reducing costs and ensuring seamless communication between vehicles and infrastructure, due to the high installation and maintenance costs of dedicated base stations and networks.
Innovation Solution
A method for resource allocation in V2X communication that allows user equipment (UE) to select and use specific resource units from a resource pool for direct signal transmission and reception, enabling efficient V2X communication without the need for extensive infrastructure, and supports coexistence with legacy and new radio access technologies like LTE and 5G New RAT.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated base stations and networks are installed for V2X communication, then communication reliability is improved, but installation and maintenance costs increase
Solution Approach 1:
The patent enables user equipment to autonomously select and use resources from a resource pool for V2X communication without requiring dedicated base station infrastructure. This self-service approach allows vehicles and infrastructure to communicate directly using pre-configured resource pools, eliminating the need for expensive dedicated network installation and maintenance while maintaining communication reliability through autonomous resource management
Solution Approach 2:
The patent creates a universal resource pool that can be shared by multiple user equipments for V2X communication. This multi-functional resource pool serves various communication needs (vehicle-to-vehicle, vehicle-to-infrastructure) without requiring separate dedicated infrastructure for each function, thereby reducing overall installation and maintenance costs while maintaining reliable communication across different V2X scenarios
2Ease of manufacture
If resource pools are shared among multiple UEs, then infrastructure costs are reduced, but resource allocation complexity increases
Solution Approach 1:
The patent pre-configures resource pools with specific resource units before V2X communication begins. User equipment can directly select from these pre-organized resource units without requiring complex real-time allocation decisions. This preliminary organization of resources simplifies the allocation process during actual communication while still enabling cost-effective shared infrastructure usage
Solution Approach 2:
The patent divides the shared resource pool into distinct resource units that can be independently selected and used by different user equipments. This segmentation allows for organized, manageable resource allocation where each UE can select specific units without creating overall system complexity, balancing cost reduction with manageable allocation processes
3Adaptability or versatility
If legacy LTE and new 5G RAT systems coexist, then system compatibility is improved, but signal transmission interference may increase
Solution Approach 1:
The patent applies different resource pool configurations and transmission parameters locally to different radio access technology systems (LTE and 5G New RAT) within the same V2X communication framework. By allowing each RAT type to use optimized local resource allocations and transmission characteristics, the system maintains compatibility between legacy and new technologies while minimizing interference through localized parameter optimization rather than uniform global settings

AI summary
The present invention relates to a method and a device for transmitting a signal of mobility, for transmission or reception of a first radio access technology (RAT)-based signal in a wireless communication system. Specifically, the method comprises the steps of: generating a first RAT-based signal including a message relating to generation of an event; duplicating the message into a second RAT-based signal when the event is associated with a safety service; and transmitting the second RAT-based signal through a resource area associated with the first RAT when the event is associated with the safety service.
