Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synchronization signals are transmitted with fixed periods and positions, then system compatibility and detection reliability are maintained, but resource efficiency decreases and power consumption increases
Solution Approach 1:
The patent applies dynamics by making the synchronization signal transmission configurable and adaptable. The network can dynamically adjust whether to transmit synchronization signals in different slots based on actual service requirements, transitioning from a static fixed-period transmission to a dynamic on-demand transmission pattern.
Solution Approach 2:
The patent changes the transmission parameters of synchronization signals by introducing configurable transmission periods and positions. Different synchronization signal types (first type and second type) can have different transmission patterns, allowing the system to optimize power consumption by adjusting these parameters based on service needs.
2Adaptability or versatility
If synchronization signals are transmitted with fixed periods and positions, then system compatibility is maintained, but resource efficiency and flexibility decrease
Solution Approach 1:
The patent enables dynamic configuration of synchronization signal transmission patterns. The network can adaptively select different transmission slots and periods based on service requirements, achieving time-domain flexibility while improving resource utilization by avoiding unnecessary transmissions.
Solution Approach 2:
The patent segments synchronization signal transmission into different types (first type and second type) with different transmission patterns. This segmentation allows the system to apply different resource allocation strategies to different signal types, improving overall resource efficiency while maintaining necessary functionality.
3Reliability
If synchronization signals are transmitted in all slots, then detection reliability is ensured, but power consumption increases
Solution Approach 1:
The patent implements periodic action by allowing synchronization signals to be transmitted in specific slots according to configurable patterns rather than continuously in all slots. The network can set different transmission periods for different synchronization signal types, achieving energy savings while maintaining detection reliability through periodic transmissions.
Solution Approach 2:
The patent extracts unnecessary synchronization signal transmissions from the transmission schedule. By identifying and removing redundant transmissions while retaining essential ones, the system reduces power consumption without compromising detection reliability, effectively taking out the harmful excessive transmission components.
