1Productivity
If machine learning algorithms are used to dynamically adjust network parameters, then network performance and throughput are improved, but system complexity increases
Solution Approach 1:
An AI module is introduced as an intermediary between the network device and terminal devices. This module collects network condition data, processes it through machine learning algorithms to generate predictions about optimal resource allocations, and sends these predictions to the network device for implementation. This intermediary structure isolates the complexity of ML algorithms from the core network device while still enabling advanced optimization capabilities.
Solution Approach 2:
The system employs self-learning machine learning models that automatically improve their predictions over time by processing historical network data and feedback. The AI module continuously refines its understanding of network conditions and resource allocation patterns without requiring manual reconfiguration, enabling the system to serve itself and automatically optimize performance while managing its own complexity.
2Productivity
If AI-based dynamic bandwidth allocation is implemented, then resource allocation efficiency is improved, but signaling overhead increases
Solution Approach 1:
The system extracts only the essential resource allocation parameters from the full AI prediction output and transmits these specific parameters to terminal devices. Instead of sending complete resource indication information for all possible resource blocks, the system identifies and transmits only the critical allocation decisions, significantly reducing signaling overhead while maintaining allocation efficiency.
Solution Approach 2:
The patent changes the representation parameters of resource allocation from detailed resource block level indications to aggregated resource indication information. By transforming the parameter structure to use resource indication values that represent groups of resource blocks rather than individual blocks, the system reduces the amount of signaling data required while preserving the ability to efficiently allocate resources.
3Reliability
If machine learning models predict resource allocations, then network performance is improved, but data processing requirements increase
Solution Approach 1:
The AI module performs partial processing by generating predictions for only the most relevant resource allocations based on current network conditions and terminal device requirements. Rather than computing optimal allocations for all possible scenarios and devices, the system focuses computational effort on the subset of allocations that will have the greatest impact on network performance, reducing overall data processing requirements while maintaining reliability.
