1Reliability
If a common synchronization configuration is used for all operation modes, then device complexity is reduced, but service reliability and latency requirements cannot be met for diverse services
Solution Approach 1:
The patent segments the synchronization configuration into multiple operation modes (first operation mode and second operation mode), each with dedicated synchronization signal transmission configurations. This allows different services to be assigned to different operation modes with optimized parameters, achieving high reliability for diverse services without requiring a single complex universal configuration.
Solution Approach 2:
The patent implements dynamic switching between different operation modes based on service requirements. The base station can dynamically adjust the synchronization signal transmission configuration by switching operation modes, enabling the system to adapt to varying latency and reliability requirements of different services while maintaining manageable complexity through standardized mode definitions.
2Productivity
If synchronization configurations are optimized for specific services, then service performance is improved, but resource allocation efficiency decreases
Solution Approach 1:
The patent creates a universal operation mode framework where each operation mode can serve multiple services with similar requirements. By defining standardized operation modes that can be reused across different service types, the system achieves service-specific optimization without sacrificing overall resource allocation efficiency, as the same operation mode configuration can be applied to multiple services.
Solution Approach 2:
The patent optimizes communication efficiency by changing synchronization signal transmission parameters (such as transmission periodicity, time-frequency resources) based on operation modes. This allows the system to adjust parameters to match service requirements while maintaining efficient resource utilization through systematic parameter management rather than ad-hoc optimization.
3Object-affected harmful factors
If different synchronization configurations are used for different operation modes, then interference management is improved, but device complexity increases
Solution Approach 1:
The patent segments interference management into different operation modes, where each mode has dedicated synchronization signal transmission configurations designed to minimize interference for that specific mode. By confining interference management strategies to specific operation modes rather than attempting a universal approach, the system reduces overall complexity while effectively managing interference for each service type.
