Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reference signal transmission timing is determined based on predefined timeline relations or base station indications, then the terminal can determine when to send the reference signal, but the timing determination process becomes complex and uncertain
Solution Approach 1:
The base station pre-configures offset values (K1, K2, K3) and timing relationships before actual signal transmission. These predefined parameters enable the terminal to calculate the exact transmission timing without complex real-time determination, resolving the contradiction between reliable timing and process complexity
Solution Approach 2:
The patent introduces multiple configurable parameters (offset values K1, K2, K3, timing advance values) that can be adjusted to optimize timing relationships. By changing these parameters, the system achieves precise timing control while maintaining a relatively simple determination process at the terminal
2Adaptability or versatility
If the base station sends trigger signaling or activation signaling for the reference signal, then the reference signal can be sent on demand, but the terminal needs to determine the timing based on complex timeline relations
Solution Approach 1:
The base station pre-configures all necessary timing parameters (offset values, timing relationships) before triggering reference signal transmission. When trigger signaling is sent, the terminal can immediately calculate the transmission timing using these pre-configured parameters, avoiding time-consuming real-time determination while maintaining flexible on-demand transmission
Solution Approach 2:
The patent introduces offset values (K1, K2, K3) as intermediary parameters that mediate between the trigger signaling and the actual reference signal transmission timing. These intermediaries simplify the timing calculation process, allowing the terminal to quickly determine transmission time without complex timeline relation analysis
