Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices communicate using a single radio access type, then device compatibility is improved, but communication versatility across different radio access types deteriorates
Solution Approach 1:
The system enables devices to perform multiple communication functions by supporting both direct V2X communication and network-based communication through the same device. The method allows a single device to operate across different radio access types (LTE and NR) by determining appropriate transmission parameters based on application priorities and preemption configurations, thereby achieving multi-functionality without requiring separate dedicated devices for each communication type.
Solution Approach 2:
The system dynamically selects transmission radio access types and carrier frequencies based on real-time conditions, including application priorities and preemption configurations. This dynamic adaptation allows the communication system to switch between different radio access types (LTE/NR) and frequency configurations depending on service requirements, resolving the contradiction between maintaining compatibility and achieving versatility.
2Adaptability or versatility
If multiple V2X applications operate simultaneously, then communication functionality is improved, but interference between applications worsens
Solution Approach 1:
The system applies different transmission parameters and preemption configurations to different V2X applications based on their specific requirements. Each application receives tailored resource allocation and priority treatment, allowing multiple applications to operate simultaneously with minimized interference. The AS layer determines appropriate radio access types and carrier frequencies for each application individually, ensuring localized optimization rather than uniform treatment.
Solution Approach 2:
The system pre-configures preemption settings and priority levels for different V2X applications before communication occurs. This preliminary configuration enables the system to preemptively manage resource allocation and prevent interference between applications. By establishing priority rules and preemption configurations in advance, the system can rapidly respond to multiple application demands without causing harmful interference.
3Adaptability or versatility
If the system supports multiple radio access types, then communication versatility is improved, but system complexity worsens
Solution Approach 1:
The application layer and AS layer act as intermediaries that manage the complexity of multiple radio access types. The application layer determines transmission requirements based on V2X application priorities, while the AS layer translates these requirements into specific radio access type selections and carrier frequency configurations. This intermediary structure abstracts the complexity from the core communication functions, allowing the system to support multiple radio access types without overwhelming system complexity.
