Abstract: The present disclosure relates to techniques for adaptively controlling and optimizing radio configuration parameters by using a dual control algorithm. The dual control algorithm includes 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.
