Workgroup Number

WG8

Workgroup Name

O-RAN Stack Reference Design Working Group

Workgroup Charter

Develop the software architecture, design, and release plan for the O-RAN Central Unit (O-CU) and O-RAN Distributed Unit (O-DU) based on O-RAN and 3GPP specifications for the NR protocol stack.

Develop specifications for interoperability testing of O-RAN O-CU and O-DU deployment scenarios with other O-RAN components in standalone (SA) mode.

Workgroup Scope

Must have:

• L1, L2, and L3 software architecture and design for the O-RAN Central Unit (O-CU) and O-RAN Distributed Unit (O-DU)

• API definitions to internal component

• API definitions to external components, e.g., RIC and Whitebox (coordinate with external WGs)

• API definitions for OAM

Software Stack Assumptions:

• All source code development and management will be under OSC/TOC

• 5G SA only

• Support FR1 and FR2

• Support O-CU/O-DU integrated/split architecture
