V2X Communication Parameter Selection for Service-Specific Resource Allocation

The patent implements dynamic resource allocation where transmission parameters (time, frequency, power) are adjusted based on service requirements, channel conditions, and traffic load. This allows resources to be dynamically reassigned between different services and terminal devices, improving both reliability for critical services and overall resource utilization efficiency.

The patent changes transmission parameters (such as modulation scheme, coding rate, transmit power, resource block allocation) based on service type and channel conditions. By adjusting these parameters, the system can guarantee reliability for high-priority services while optimizing resource usage across the network, resolving the contradiction between dedicated resource allocation and resource efficiency.

The patent applies different transmission parameter configurations to different services based on their specific requirements. High reliability services receive parameters optimized for error correction and retransmission, while low-latency services receive parameters that minimize transmission time. This localized optimization resolves the contradiction by tailoring parameters to each service's needs rather than using a one-size-fits-all approach.

The patent segments services into different categories (e.g., safety-critical, comfort, control) and applies different transmission parameter sets to each category. This segmentation allows the system to simultaneously optimize for reliability in critical services while maintaining low latency in time-sensitive services, resolving the contradiction between reliability and delay.

The patent pre-configures multiple sets of transmission parameters corresponding to different service types before actual communication occurs. When a service is initiated, the appropriate parameter set is selected based on service identification, avoiding the need for complex real-time calculations. This preliminary configuration approach maintains high service adaptability while reducing system complexity during operation.

The patent creates a universal parameter configuration framework that can accommodate multiple service types through a standardized structure. Rather than implementing separate complex systems for each service, a single multi-functional parameter management system handles all service types, reducing overall system complexity while maintaining adaptability to different service requirements.
