Solution Approach 1:

The patent segments the radio configuration parameter optimization into two distinct parts: (1) UE clustering using classification algorithms with predefined input parameters, and (2) radio configuration parameter optimization using Reinforcement Learning. This segmentation allows each algorithm to focus on specific tasks, reducing the overall complexity of input parameter selection while maintaining performance improvements.

AI summary

The present disclosure relates to techniques for adaptively controlling and optimizing radio configuration parameters by using a dual control algorithm. The dual control algorithm comprises first and second control algorithms, each of which is executed independently whenever certain one or more trigger events occur. The first control algorithm is used for obtaining one or more User Equipment (UE) clusters and a Key Performance Indicator (KPI) requirement for each UE cluster based on UE information, while the second control algorithm is used for obtaining optimized radio configuration parameters for each UE cluster in accordance with the KPI requirement. The second control algorithm is also configured to monitor its performance and, if its performance degrades, send an associated signal to the first control algorithm. The occurrence of such a signal is among the trigger events that cause the execution of the first control algorithm.
