Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current V2X communication technologies, such as IEEE 802.11p-based DSRC, face limitations in message arrival distance between vehicles, necessitating the development of more effective cellular-based V2X standards for enhanced vehicle platooning and communication services across different mobile communication operators.
Innovation Solution
A method for processing control signals in a wireless communication system, involving receiving and processing control signals from a network entity, determining parameter values for vehicle communication services, and transmitting responsive messages, with the ability to select vehicle platooning groups and share information across public land mobile networks (PLMNs), enabling efficient vehicle platooning and communication services.

Engineering Contradiction Analysis
1Length of stationary object
If IEEE 802.11p-based DSRC is used for V2X communication, then vehicle-to-vehicle communication can be established, but the message arrival distance between vehicles is limited
Solution Approach 1:
The patent introduces a network entity (base station) as an intermediary to relay V2X messages between vehicles. Instead of direct vehicle-to-vehicle communication only, messages can be transmitted through the network entity, extending the effective communication distance while maintaining reliability through infrastructure support.
Solution Approach 2:
The patent enables the V2X communication system to support multiple communication modes (direct vehicle-to-vehicle and network-relayed communication) within a single framework. This multi-functional approach allows the system to adapt to different distance requirements and network conditions, resolving the contradiction between distance extension and reliability maintenance.
2Length of stationary object
If cellular-based V2X standards are implemented to extend communication range, then message arrival distance increases, but system complexity increases
Solution Approach 1:
The patent divides the V2X communication system into distinct functional modules: vehicle units, network entities, and parameter management components. Each module handles specific tasks independently, reducing overall system complexity while enabling extended communication range through coordinated operation of these segmented components.
Solution Approach 2:
The patent implements preliminary configuration of communication parameters (such as message intervals, transmission power, and group IDs) before actual V2X communication begins. This pre-configuration approach simplifies real-time operation by eliminating the need for complex dynamic parameter adjustment during communication, thereby reducing system complexity while maintaining extended range capability.
3Productivity
If parameter-based processing is implemented for vehicle communication services, then communication efficiency improves, but information processing complexity increases
Solution Approach 1:
The patent utilizes parameter changes (such as message intervals, transmission power levels, and group identifiers) to control and optimize V2X communication. By managing a limited set of well-defined parameters rather than complex message content, the system achieves high communication efficiency while keeping information processing relatively simple through standardized parameter interpretation.
