5G FAPI specs updated with richer 3GPP feature set
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, as identified by the study undertaken by the Small Cell Forum; this virtualization is already enabled for 4G via 4G-nFAPI. These specifications define an equivalent transportable interface for MAC-PHY 5G function application platform interface (5G-FAPI) defined for 5G small cells.
This RAN architecture virtualization MAC function is also known as the Option 6.
These specifications comprise:
