Updated: 23 April 2020
Risks:
- E2SM Specification baseline is still not available while the development is being done using below draft specifications.
- ORAN WG3.E2AP v01.00
- ORAN WG3.E2SM v01.00
- WLS, FAPI interface files baseline - FAPI interface development is dependent on this.
- UE Attach Scenario development - Completed till msg-2, remaining scope moved to C release as E2 changes were included in the scope.
Status:
Raised 18 change requests in WG8 AAD Specification; Already presented to the WG8 Task groups to be addressed in subsequent releases of the document.
O-DU High layers (MAC, RLC, and app):
- Re-align seed code to 3GPP Release 15.3.0 - WIP
- Align seed code to WG8 AAD specification and interfaces - MAC - RLC Interface is done, RLC-F1AP interface is WIP
- 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- Cell Broadcast procedure - WIP
- UE attach - Open
F1-U interface development - Done
E2 Traffic Steering implementation based on draft specification - Done (with some limitations due to specifications)
F1-C interface enhancement: Done (procedures identified for bronze released is done)
- 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 - Open
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 of test infrastructure i.e UE or UE simulator, O-RU, O-CU, and core components.

Risks:
- E2SM Specification baseline is still not available while the development is being done using draft specifications
- WLS, FAPI interface files baseline - FAPI interface development is dependent on this.
- UE Attach Scenario development - in medium risk due to the effort needed to complete the development
Status:
Raised 16 changes in WG8 AAD Specification; working with Ganesh to get them addressed in the next release of the document.
