Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional beamforming synchronization methods are used, then timing synchronization can be performed, but beam tracking is slow and synchronization failure rate is high
Solution Approach 1:
The patent segments the synchronization signal transmission into multiple directional beams, where each beam transmits synchronization signals in different spatial directions. This allows the receiving device to simultaneously track multiple beams, significantly reducing beam tracking time while improving synchronization reliability through diverse beam selection
Solution Approach 2:
The patent implements periodic beam sweeping where synchronization signals are transmitted in different directions at different time intervals. This periodic action enables the receiving device to track beam changes over time and select optimal beams, resolving the contradiction between fast tracking and reliable synchronization
2Productivity
If multiple antenna beams are used for synchronization, then beam tracking speed improves, but system complexity increases
Solution Approach 1:
The patent makes the synchronization signal transmission structure universal by designing it to support multiple antenna beams with different directions and configurations. This multi-functional design enables fast beam tracking while maintaining manageable system complexity through standardized procedures
Solution Approach 2:
The patent performs preliminary beam configuration and synchronization signal transmission in advance, allowing the receiving device to pre-track multiple beams and select optimal ones before actual data transmission. This preliminary action speeds up beam tracking while keeping system complexity controlled through pre-planned configurations
