ETSI and O-RAN are pleased to announce that ETSI has adopted the first O-RAN specification as ETSI TS 103 859, namely ‘O-RAN Fronthaul Control, User and Synchronization Plane Specification v7.02’. The document focuses on Open Fronthaul, one of the interfaces in the O-RAN Architecture for open and intelligent Radio Access Networks. It specifies the control plane, user plane and synchronization plane protocols used over the fronthaul interface linking the O-DU (O-RAN Distributed Unit) and the O-RU (O-RAN Radio Unit) for the lower layer functional splits. The scope of TS 103 859 includes both LTE and NR (5G).
