SUMMARY:RAN Automation using Reinforcement Learning: the cases of Mobility
 Robustness Optimization and MU-MIMO Frequency Scheduling
DESCRIPTION:This talk will present the ongoing activities at Ericsson
 Research in Massy\, France related to RAN automation. After a general
 presentation\, we will discuss in detail two specific use cases:\n\n(a) the
 Mobility Robustness Optimization for intra-frequency handover\; we learn to
 automatically tune the Cell Individual Offset of each cell boundary using
 offline Reinforcement Learning without exploration\, by exploiting already
 collected data.\n\n(b) the frequency scheduling of users to sub-bands
 supporting MU-MIMO concurrent transmission. This is a challenging
 large-action and large-state space problem which we tackle using online
 action decomposition methods inspired my multi-agent reinforcement learning
 (MARL) and Graph Neural Networks (GNNs).\n\nIn both use cases we show that
 AI-methods outperform traditional rule-based solutions and highlight the
 potential benefits from AI in RAN automation of future 6G
 networks.\n\nReferences:\n\n[MRO] “Offline Reinforcement Learning for
