Summary of current efforts on ML applications for traffic steering in O-RAN.

Year Ref Contribution
2021 [4] Proposed logistic regression for modular and flexible O-RAN in 6G networks, focusing on traffic steering and O-RAN xApps.
2022 [51] Introduced federated meta-learning with DQN for privacy-preserving multi-RAT knowledge sharing.
2022 [52] Proposed Q-learning-based algorithm for power and frequency allocation in O-RAN to minimize macro gNB interference and maximize device QoS.
