Near Realtime RAN Intelligent Controller Platform (E2 Interface) (RIC-PLT)

Primary Goals: TODO

Cherry feature scope: TODO 

PTL: Thoralf Czichy

Status TODO



Non-Real-time RIC (A1 Interface) (NONRTRIC)

Primary Goals: The primary goal of Non-RT RIC is to support intelligent RAN optimization by providing policy-based guidance, ML model management and enrichment information to the near-RT RIC function so that the RAN can optimize, e.g., RRM under certain conditions.
It can also perform intelligent radio resource management function in non-real-time interval (i.e., greater than 1 second).
Non-RT RIC can use data analytics and AI/ML training/inference to determine the RAN optimization actions for which it can leverage SMO services such as data collection and provisioning services of the O-RAN nodes.TODO

Bronze Feature Scope:
Initial design and start implementation of NONRTRIC Platform.
Continue evolution of A1 interface.
Continue evolution of A1 Policy Management functions.
Modeling and implementation of the Non-RealTime RIC aspects of the "Health Check" and "Traffic Steering" use casesTODO

    O-DU High

    Primary Goals:  Develop Amber release code to enhance O-DU layers source codeTODO

    Bronze Feature Scope:  

    • O-DU High layers (MAC, RLC and app):
      • Re-align seed code to 3GPP Release 15.3.0
      • Align seed code to WG8 AAD specification and interfaces
      • Implementation of cell broadcast procedure and UE attach procedure (SA mode)
        for FDD mode and FR1 (Numerology = 0, Bandwidth = 20 MHz) and basic scheduler APIs for single UE and single HARQ transmission
    • F1-U interface development
    • F1-C interface enhancement: 
      • Support for following additional F1AP messages:
        • Initial UL RRC Message Transfer
        • UL/DL RRC Message Transfer
        • UE Context Setup Request/Response
      • Enhance F1AP messages:
        • F1AP Setup Request/Response
        • GNB DU Config Update
    • Basic FAPI messages Implementation

    Out of Scope:

    • Use cases – Traffic Steering, Health Check related messages and call flows
    • TDD functionality, NSA
    • End to end testing

    Limitations/Dependencies:

    • FAPI Implementation – Dependency on O-DU Low to open source WLS files, interface files
    • Testing: Currently only some unit testing can be done due to lack test infrastructure i.e UE or UE simulator, O-RU, O-CU and core components.
