pe of the architecture and use cases, assigns task group leads, and drives completion of the task in cooperation with other O-RAN work groups. WG2: The Non-RealTime (RT) RAN Intelligent Controller (RIC) and A1 Interface Workgroup Focuses on radio resource management, higher-layer procedure optimization, policy optimiza- tion in RAN, and providing artificial intelligence/machine learning (AI/ML) models to near-RT WG3: The Near-real-time RIC and E2 Interface Workgroup Enables near-real-time control and optimization of RAN elements and resources via data collec- tion and actions over E2 interface. WG4: The Open front-haul Interfaces Workgroup Specifies an open front-haul interface, which enables true multivendor interoperability in the RAN. Provides guidelines for time synchronization requirements on the various RAN compon- ents: the Radio Unit (RU), the Distributed Unit (DU), and the Control Unit (CU). WG5: The Open F1/W1/E1/X2/Xn Interface Workgroup Provides fully operable multivendor specifications (compliant with 3GPP specification) for the F1/W1/E1/X2/Xn interfaces and in some cases will propose 3GPP specification enhancements. These interfaces are a collection of virtual connections between components in the RAN (spe- cified originally by 3GPP). WG6: The Cloudification and Orchestration Workgroup Defines specification to decouple RAN software from underlying hardware to leverage the be- nefits of being able to use commodity hardware platforms. WG7: The White-box Hardware Workgroup Specifies and releases a complete reference design for open hardware platforms for the various RAN components, including Picocells. WG8: Stack Reference Design Workgroup Develops the software architecture, design, and release plan for the O-RAN open DU and open CU as per 3GPP specifications for the NR protocol stack. WG9: Open X-haul Transport Work Group Focuses on the 5G transport design and provides a reference architecture blueprint for network deployment. There is also another organization to mention: The O-RAN Software Community
