Primary Goals: Support near-real-time radio resource management via development and deployment of a series of xApps that interact with one another and the external components via A1, O1, and E2 interfaces (O-CU/O-DU)

Planned xApps: (1) Admission Control; (2) Measurement Campaign; (3) UE Manager; (4) ML xApp; (5) KPI Monitor

Active participation from AT&T, Nokia, Samsung

5 xApps being worked for Amber:
Admission Control (AC)
Measurement Campaign
UE Manager
ML-based AC
KPI monitor
xApp interaction methods
Using RIC Message Router (RMR)
Using Shared Data Layer (SDL)
Planning for use of ML in xApps

Primary Goals: Support near-real-time radio resource management, managing O-CU’s and O-DU’s via E2 messages, receiving A1 intent and policy guidance messages from the non-RT RIC, O1 configuration requests, and emitting O1 measurement data to ONAP.
Platform Components: (1) xApp and Config Manager; (2) A1 xApp mediator; (3) Routing Manager; (4) Subscription Manager; (5) E2 Manager; (6) Redis RAN R-NIB; (7) Redis xApp DB2; (8) E2 Termination; (9) Resource Manager; (10) Logging and OpenTracing; (11) Prometheus; (12) VES Agent / VESPA; and (13) API Gateway

Key Progress & Open Issues
E2: Implements WG3 General Aspects and Principles
Amber release with support E2 Insert Messages
A1: No alignment with WG as yet
O1: LCM via xApp manager providing REST APIs
RMR RIC-internal transport function
Integrated with Akraino REC Edge Stack

Target:  Provide the infrastructure to vO-CU and vO-DU, include the VM and Container solutions.  Enable the AAL (accelerator abstract layer) for the RAN application VNF/CNF.

Active participation from Windriver and Lenovo.

4 Epics defined and in-progress; 1 Deferred to Rel B

• [INF-A-F01] Akraino blueprint for RIC
• [INF-A-F02] VNF/CNF Orchestration (Inspur)
• [INF-A-F03] Acceleration Abstraction Layer (AAL)
• [INF-A-F04] Real time platform to deploy the O-CU and O-DU

Primary Goal: Support non-real-time radio resource management, higher layer procedure optimization, policy optimization in RAN, and providing guidance, parameters, policies and AI/ML models to support the operation of near-RealTime RIC functions in the RAN to achieve higher-level non-real-time objectives.
Project Scopes: (1) A1 controller (mediator, Endopoint); (2) Coordinate/Host A1 Policy Management Services; (3) Coordinate AI/ML models – in RAN (E2 nodes and near-RT RIC) and non-RT RIC; (4) Data Enrichment coordinator; and (5) rApp Host and SMO Application Coordinator.

9 Epics, 10 user stories and 3 tasks defined (all open)
None targeted for completion in Amber!
Working on several stretch goals:
Use SDNC as the base controller for NONRTRIC functions
Reuse Near-RT RIC dashboard to generate simple A1 messages
Leverage sample Near-RT RIC AdmissionControl xApp

Primary Goals: The O-DU (High) project provides reference implementation according to the O-RAN WG8 documents. It provides the implementation of F1AP, RLC, MAC, Scheduler modules and API between them.
Scope: Develop software deliverable for the A-release as per SW requirements specifications, leveraging seed code of 5GNR RLC and MAC protocol functions and developing F1AP module, CU stub and L1 Stub.

O-DU-OAM-Agent – Work In Progress
Initial bring up of the system and layer configuration.
MAC-PHY (FAPI) Interface
Discussions with the O-DU Low team is in progress.
Test code development is WIP for initial PHY configuration message.
F1AP: Following messages between CU and DU are being developed.
F1 SETUP REQUEST
F1 SETUP RESPONSE
GNB-DU CONFIGURATION UPDATE
GNB-DU CONFIGURATION UPDATE ACKNOWLEDGE

Primary Goals: The O-RAN-SC-ODU LOW project provides reference implementation of ODU-LOW according to the O-RAN AAL specification (WG8) documents. The reference design will follow the open interface toward ODU HIGH, RRU and Accelerator, provide physical layer signal processing functionality according to 3GPP .

Scope: According to the ORAN-WG8.AAD specification, PHY layer functionality is realized as High-PHY in O-DU and Low-PHY in O-RU. Some of the PHY functionalities may be realized using hardware acceleration. O-DU Low project will focus on the High-PHY and fronthaul library modules that reside in O-DU. NR FAPI being standardized by Small Cells Forum (SCF) will be used for defining L1 and L2 interactions.
