5G FAPI SPECS UPDATED WITH NEW OAM FOR INLINE HIGH-PHY
SCF has updated its 5G FAPI suite, and released a new specification SCF229 5G FAPI Operations, Administration and Maintenance (OAM) Protocol For Inline High-PHY, bringing to Open RAN fuller virtualized support of inline High-PHY implementations in O-RAN Alliance architecture. These latest releases are further indication of the FAPI suite evolving and meeting industry requirements, and it demonstrates SCF’s commitment to consistently updating and expanding the APIs.FIND OUT MORE
The 5G network functional application platform interface (5G nFAPI) is an initiative that extends for 5G the functional split between the MAC and PHY functions that enables virtualization of the MAC function. This document defines a transportable interface for MAC-PHY 5G function application platform interface (5G-FAPI) defined for 5G small cells [SCF222]. This RAN architecture virtualization MAC function [SCF159] is also known as the Option 6 [3GPP TR 38.816, v15.0.0] architecture split.Download
5G nFAPI [SCF225] adds a network transport wrapper around the 5G FAPI PHY API [SCF222] to create the split 6 interface between S-RU and S-DU small cell network units which SCF describes as Open6. This paper is not a specification. It considers how to test the disaggregated units S-RU and S-DU of the RAN.Download
SCF has released two iterations of its nFAPI specification that enable early implementations for evaluation by mobile operators and other small cell deployers. In this informative companion document to the normative specification we provide an overview of the specification’s application, a roadmap for ongoing feature implementation and ecosystem support, and an FAQ.Download
Network FAPI provides a ‘wrapper’ for PHY FAPI and RF FAPI to make them transportable over network interfaces. The FAPI and network FAPI together define the split option 6 network interface between S-RUs and S-DUs.
The main changes to the latest version of the nFAPI specifications include:
