1Productivity
If beam hopping is implemented to reduce single-satellite load and improve resource utilization, then satellite system resource utilization is improved, but beam distribution complexity and signaling overhead increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring beam hopping patterns and beam configuration information before actual beam hopping operations. The network device pre-determines multiple beam hopping patterns and configures them to the terminal device in advance, allowing the terminal to quickly switch between beams without complex real-time calculations, thus reducing signaling overhead while maintaining high resource utilization.
Solution Approach 2:
The patent implements dynamics by making beam hopping patterns adaptive and configurable. The network device can dynamically select from multiple pre-configured beam hopping patterns based on current network conditions, satellite position, and service requirements. This dynamic configuration allows the system to optimize resource utilization while managing beam distribution complexity through flexible, condition-based pattern selection.
2Measurement precision
If detailed beam configuration information is transmitted to terminals, then beam distribution accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts only the essential beam configuration information needed for accurate beam distribution while omitting redundant details. Instead of transmitting complete beam configuration data, the network device transmits compact beam hopping pattern indices or simplified configuration parameters that reference pre-defined beam patterns, thereby maintaining beam distribution accuracy while significantly reducing signaling overhead.
Solution Approach 2:
The patent uses copying by creating compact representations of beam configuration information. Pre-defined beam hopping patterns are stored in the network device, and only references or indices to these patterns are transmitted to terminals. This copying approach allows terminals to reconstruct accurate beam distribution information from compact representations, reducing signaling overhead while preserving beam distribution precision.
3Reliability
If beam hopping patterns are frequently updated to adapt to satellite motion, then communication reliability is improved, but power consumption and signaling overhead increase
Solution Approach 1:
The patent applies periodic action by updating beam hopping patterns at optimized intervals rather than continuously. The network device determines appropriate update periods based on satellite orbital characteristics, beam coverage duration, and communication service requirements. This periodic update approach maintains communication reliability by keeping beam configurations synchronized with satellite position while reducing terminal power consumption compared to continuous updates.
Solution Approach 2:
The patent uses parameter changes by modifying key beam hopping parameters (such as pattern selection, hopping rate, or active beam identifiers) rather than completely reconfiguring all beam parameters. The network device identifies and updates only the necessary parameters that need adjustment due to satellite motion, reducing the computational and energy burden on terminals while maintaining communication reliability through targeted parameter optimization.
