Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple SSB resource configurations are maintained for different scenarios, then system adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic SSB resource configuration where the network can switch between different SSB resource settings based on operational scenarios. The system maintains multiple SSB resource configurations but dynamically activates only the relevant ones, allowing the system to adapt to different scenarios (energy-saving mode vs. traditional mode) without permanently maintaining all configurations, thus reducing overall device complexity while preserving adaptability.
Solution Approach 2:
The patent creates a universal SSB resource configuration mechanism that can serve multiple scenarios. By designing a unified configuration framework that works for both energy-saving mode and traditional non-energy-saving mode, the system achieves multi-functionality without requiring separate dedicated configurations for each scenario, thereby reducing device complexity while maintaining versatility.
2Use of energy by moving object
If SSB transmission resources are reduced for energy saving, then energy efficiency is improved, but signal reliability may deteriorate
Solution Approach 1:
The patent implements periodic SSB transmission where synchronization signals are sent at specific intervals rather than continuously. This periodic action allows the network to save energy by reducing transmission frequency while maintaining signal reliability through regular updates at predetermined periods, ensuring UEs can still synchronize effectively without requiring continuous SSB transmissions.
Solution Approach 2:
The patent changes key transmission parameters including SSB periodicity, time domain resource positions, and frequency domain allocations based on network conditions and energy-saving requirements. By dynamically adjusting these parameters, the system optimizes the balance between energy consumption and signal reliability, reducing transmissions when energy saving is prioritized while maintaining adequate signal quality for UE synchronization.
3Use of energy by moving object
If time domain resource assignment is optimized for energy saving, then energy efficiency is improved, but resource utilization flexibility may be reduced
Solution Approach 1:
The patent implements dynamic time domain resource assignment where SSB transmission time positions are adjusted based on network conditions and energy-saving requirements. The system can dynamically select from multiple predefined time domain configurations, allowing flexible resource allocation that adapts to different operational scenarios while optimizing energy consumption through reduced transmissions during low-activity periods.
4Adaptability or versatility
If multiple SSB resource configurations are supported, then system versatility is improved, but signaling overhead increases
Solution Approach 1:
The patent segments SSB resource configurations into separate, independently configurable parameters including time domain positions, frequency domain allocations, and periodicity settings. This segmentation allows the network to configure and signal only the specific parameters that need to be changed for different scenarios, rather than transmitting complete configuration sets, thereby reducing signaling overhead while maintaining the ability to support multiple scenarios.
