A method of optimizing synchronization signal block (SSB) beam configuration for 3rd Generation Partnership Project (3GPP) New Radio (NR) network includes: using at least one of an artificial intelligence (Al) and machine learning (ML) engine in one of service management and orchestration (SMO) module, non-real time radio access network intelligent controller (Non-RT RIC), and near-real time radio access network intelligent controller (Near-RT RIC), to derive at least one optimal SSB beam configuration for the 3GPP NR network; and communicating, by the at least one of the AI and ML engine, the derived at least one optimal SSB beam configuration to a network node of the 3GPP NR network. Both the training and deployment of the at least one of the AI and ML engine are executed in the Non-RT RIC, and a static mapping between SSB beam identifiers (IDs) and beamforming weights (BFWs) is predefined.
