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 latest iteration includes support for 3GPP Rel-16 Remote Interference Management (RIM) and new high-resolution L1 Metrics (RSSI, RSRP and Noise+Interference): to assist the scheduling and automated logging functions.
