Multi-PC5 Carrier V2X Communication for Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing V2X communication technologies using LTE are limited by the ability to only adopt a single PC5 carrier, which restricts the speed and reliability of V2X services.
Innovation Solution
A method that allows communication between terminals through multiple carriers, where terminals determine and select pre-configured carriers based on priority, congestion level, capability, or service requirements, and send information over these carriers using time division multiplexing, ensuring resource allocation and service data are transmitted effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single PC5 carrier is used for V2X communication, then device complexity is reduced, but communication speed and reliability are limited
Solution Approach 1:
The patent segments the communication task across multiple PC5 carriers instead of using a single carrier. The terminal determines at least two carriers from pre-configured carriers and sends information over these multiple carriers simultaneously or sequentially, thereby improving communication reliability through diversity while managing complexity through structured carrier selection and resource allocation mechanisms
Solution Approach 2:
The patent changes the parameter of carrier quantity from one to multiple (at least two). By configuring multiple PC5 carriers and enabling the terminal to select and use multiple carriers for communication, the system transforms the single-carrier limitation into a multi-carrier capability, thereby improving both speed and reliability without excessively increasing device complexity through standardized selection criteria
2Productivity
If multiple carriers are used for V2X communication, then communication speed and reliability improve, but resource consumption increases
Solution Approach 1:
The patent applies partial action by having the terminal determine and use at least two carriers from pre-configured carriers rather than all available carriers. The terminal selectively activates only the necessary number of carriers based on communication needs, thereby improving speed and reliability while avoiding the excessive energy consumption that would result from using all available carriers continuously
Solution Approach 2:
The patent implements preliminary action by pre-configuring multiple carriers before communication begins. The network side pre-configures at least two carriers for the terminal, and the terminal pre-determines which carriers to use based on these pre-configured options. This preliminary configuration reduces real-time decision complexity and energy consumption during actual communication operations
3Reliability
If multiple carriers are used for V2X communication, then communication reliability improves, but system complexity increases
Solution Approach 1:
The patent implements self-service by enabling the terminal to autonomously determine at least two carriers from pre-configured carriers based on predefined criteria. The terminal independently performs carrier selection and resource allocation without requiring continuous network intervention, thereby improving service transmission reliability while reducing the operational complexity of managing multiple carriers through automated decision-making mechanisms

AI summary
A method for communication between terminals, a terminal and a system are provided. The method includes steps of: determining, by a terminal, at least two carriers selected from pre-configured carriers; and sending, by the terminal, information to another terminal over the at least two carriers.
