Solution Approach 1:

The patent segments the MIMO configuration management into separate functional modules: an AI/ML module for intelligent decision-making, a configuration module for parameter management, and a feedback module for performance monitoring. This segmentation allows each module to handle specific aspects of complexity independently, making the overall system more manageable while maintaining high data rates through optimized MIMO configurations.

Solution Approach 1:

The patent applies preliminary action by pre-training AI/ML models offline using historical data and simulated network conditions. These pre-trained models are then deployed in the network to make rapid configuration decisions without requiring intensive real-time computation. This approach enables the system to achieve high spectral efficiency through optimized MIMO configurations while significantly reducing the computational energy required during actual network operation.
