We generally describe a system (100) for antenna beam selection in a radio access network. The system (100) comprises a measurement module (102) which is configured to obtain channel quality measurements of a plurality of beams usable to serve a user equipment (112) in the 5G radio access network. The system (100) further comprises a training module (104) coupled to the measurement module (102), wherein the training module (104) is configured to generate a machine learning model based on the channel quality measurements. The system (100) further comprises a prediction module (106) coupled to the training module (104), wherein the prediction module (106) is configured to receive the machine learning model from the training module (104), and select, based on the machine learning model, one of the plurality of beams used to serve the user equipment (112).
