Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current V2X communication methods are used, then the system is simple and easy to operate, but the reliability and communication range requirements cannot be ensured
Solution Approach 1:
The patent segments the communication system into multiple logical channels with different attributes (priority, reliability requirement, communication range requirement). Each logical channel is independently configured and managed, allowing the system to meet diverse reliability requirements through channel differentiation without requiring complete system redesign.
Solution Approach 2:
The patent implements dynamic resource allocation where the network device configures logical channel attributes based on real-time communication requirements. The system can dynamically adjust priority levels, reliability parameters, and communication range settings for different logical channels, enabling adaptive response to varying V2X communication demands while maintaining operational simplicity through centralized management.
2Length of stationary object
If current V2X communication methods are used, then the system configuration is simple, but the communication range requirement cannot be ensured
Solution Approach 1:
The patent divides the communication system into multiple logical channels, each with independently configured communication range requirements. This segmentation allows different parts of the system to operate at different range levels based on specific needs, enabling extended communication range for critical applications without requiring all system components to be reconfigured for maximum range.
Solution Approach 2:
The patent applies local quality by configuring specific logical channels with enhanced communication range parameters based on their particular requirements. Instead of uniformly increasing range across the entire system, the network device selectively configures range attributes for specific logical channels that require extended coverage, optimizing resource usage while meeting localized range demands.
3Reliability
If multiple logical channels with different attributes are configured, then the reliability and communication range can be ensured, but the system complexity increases
Solution Approach 1:
The patent creates a universal logical channel configuration framework that can handle multiple reliability and communication range requirements through a standardized attribute system. The network device uses a unified configuration approach that applies to all logical channels, defining attributes such as priority, reliability requirement, and communication range requirement in a consistent manner. This multi-functional configuration system can accommodate diverse V2X communication needs while maintaining manageable complexity through standardization.

AI summary
This application provides a communication method and apparatus, to help ensure a transmission reliability and/or communication range requirement. When configuring a transmission resource of a sidelink for a terminal, a network device also configures attribute information of the transmission resource. The attribute information may indicate reliability and/or a communication range corresponding to the transmission resource. The terminal device may select a matched logical channel for the transmission resource based on the attribute information of the transmission resource and attribute information of each logical channel of the terminal device. The attribute information of the logical channel is used to indicate reliability and/or a communication range of the logical channel.
