Data-Driven Orchestration for Distributed RAN Intelligent Controller Placement in 6G Networks

Proceedings of the 40th ACM/SIGAPP Symposium on Applied Computing
Open-Radio Access Network ( O-RAN ) brings an innovative approach to address the issues of controller placement in large-scale 6G networks. In this work, we introduce a Reinforcement Learning (RL ) algorithm for decentralized RAN Intelligent Controller Orchestration in 6G Networks, which leverages the online learning capabilities of a multi-agent RL ...

FlexApp: Flexible and Low-Latency xApp Framework for RAN Intelligent Controller

ICC 2023 - IEEE International Conference on Communications, 2023
RAN openness is a vision for 5G and beyond to avoid unnecessary lock-in effects. In this regard, the O-RAN alliance provides a new architecture with RAN intelligent controller (RIC) for both non-real-time and near-real-time cases, together with running applications, i.e., rApps and xApps. However, two key challenges remain in the current xApp framework:

Challenges for Conflict Mitigation in O-RAN’s RAN Intelligent Controllers

2023 International Conference on Software, Telecommunications and Computer Networks (SoftCOM), 2023
The O-RAN architecture enables a more flexible and dynamic radio access network (RAN) control by separating hardware and software components. However, the distributed nature of the O-RAN architecture also presents several challenges for mitigating network control conflicts that can arise between different network elements.
