5G FAPI: PHY API Specification
Document number: SCF222
PHY FAPI is the main API for FAPI, defining P5 and P7 interfaces for user and control plane into the PHY. Its typical application is between a PHY layer System on a Chip and the software stack for MAC and higher layer protocols. It can also be used to enable Embedded NIC Inline Accelerators for the High-PHY function in an O-RAN DU. This most recent iteration targets key 3GPP features, market performance requirements, and supports Open RAN evolution.
