Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed process quantity is configured by an access network device for a terminal device, then the configuration is simple, but the accuracy and efficiency of process quantity determination is insufficient
Solution Approach 1:
The patent transforms the fixed, static process quantity configuration into a dynamic determination mechanism. The terminal device calculates the process quantity based on real-time parameters including uplink scheduling timing, downlink scheduling timing, feedback message timing, subcarrier spacing, and transmission capability. This dynamic calculation adapts to varying network conditions and service requirements, resolving the contradiction between configuration simplicity and determination accuracy.
Solution Approach 2:
The patent introduces multiple variable parameters (scheduling timing relationships, subcarrier spacing values, transmission capability indicators) that influence process quantity determination. By changing these parameters based on different carrier configurations and service types, the system achieves accurate process quantity adaptation without complex manual configuration, balancing ease of deployment with precise determination.
2Measurement precision
If multiple factors are considered for process quantity determination, then the accuracy improves, but the complexity of determination increases
Solution Approach 1:
The terminal device autonomously determines its own process quantity by self-calculating based on received carrier information and its own transmission capabilities. The device uses built-in processing to evaluate timing relationships, subcarrier spacing, and capability parameters without requiring external assistance or complex coordination with the access network device, thereby improving accuracy while maintaining manageable complexity.
Solution Approach 2:
The access network device pre-provides essential carrier information (scheduling timing relationships, subcarrier spacing configurations) to the terminal device before data transmission begins. This preliminary provision of parameters enables the terminal device to perform accurate process quantity determination without needing to complexly negotiate or discover these parameters in real-time, reducing the computational burden during actual operation.
