Support for features not properly defined in the SCF 5G FAPI 2.0 specs has been added by means of vendor specific fields.

Increased test coverage. All supported DL, UL and FD standard MIMO cases are validated
Support for carrier aggregation
Support for API ordering
Support for handling Intel proprietary PHY shutdown message in radio mode
FAPI TM latency measurement
Bug fixes
Feedback provided to SCF on parameter gaps identified in SCF 5G FAPI specification dated March 2020
This version of the 5G FAPI TM incorporates the changes that were provided to the SCF.

First release of the 5G FAPI TM to ORAN in support of the Bronze Release
This version supports 5G only
PARAM.config and PARAM.resp are not supported
ERROR.ind relies on the L1 support for error detection as the 5G FAPI TM only enforces security checks and
integrity checks to avoid DOS attacks but it doesn’t perform full validation of the input parameters for compliance to the standard
Deviations from the March version of the SCF 5G FAPI document have been implemented in order to deal with
limitations and ommisions found in the current SCF document, these differences are being provided to the SCF for the next document update. The 5G FAPI implementation is defined in the file fapi_interface.h
Multi-user MIMO, Beamforming, Precoding and URLLC are not supported in the current implementation as they
require additional alignment between the SCF P19 and the ORAN
The option for the MAC layer doing the full generation of the PBCH payload is not supported in this release and it will be added in the maintainance release cycle.
