Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If SRS triggering is performed with fixed timing, then system simplicity is maintained, but resource utilization efficiency and communication throughput deteriorate
Solution Approach 1:
The patent applies dynamics by transitioning from fixed SRS triggering timing to dynamic triggering mechanisms. The terminal determines SRS transmission timing based on received downlink control information, allowing the system to adapt triggering moments to actual communication needs, thereby improving resource utilization efficiency while managing complexity through standardized control procedures.
Solution Approach 2:
The patent changes the timing parameter of SRS transmission from fixed to variable based on downlink control information. By allowing the triggering timing to be adjusted according to received control signals, the system optimizes resource utilization without requiring complex manual configuration, resolving the contradiction between productivity improvement and device complexity.
2Productivity
If SRS triggering is not flexibly controlled, then system operation simplicity is maintained, but communication quality and throughput deteriorate
Solution Approach 1:
The terminal autonomously determines SRS transmission timing based on received downlink control information without requiring complex external control. The system performs self-service by automatically adjusting triggering moments according to actual communication conditions, thereby improving communication throughput while maintaining operational simplicity through standardized self-adjustment mechanisms.
3Productivity
If fixed SRS triggering is used, then implementation simplicity is maintained, but resource allocation efficiency deteriorates
Solution Approach 1:
The patent implements dynamic triggering where the terminal adjusts SRS transmission timing based on received downlink control information. This dynamic approach allows efficient resource allocation by triggering SRS at optimal moments according to actual communication needs, while the standardized control mechanism prevents excessive configuration complexity.
