Scope

The page will discuss and document the necessary yang modules to be supported by O-DU to ensure the end-to-end functionality of the D-Release use case "Closed loop". 

As O-RAN alliance does not provide solid yang models yet, other data models needs to be defined or selected.

Decisions

In SMO project call on 2021-03-04 it was decided to create a yang modules for O-RAN-SC DU with a minimum parameter set supporting the D-Release Closed loop use case.

The initial idea of a configuration for the O-DU NetConf client is rejected, because in D-Release there wont be a NetConf client implemented on O-DU.

The prototype yang models from B-Release wont be enhanced.
