Primary Goals:  

The O-DU Low F release adds support for Massive MIMO, URLLC and it is based on the commercial FlexRan 21.11 release. This release is an incremental improvement over the E-maintenance reelase code released on March of this year and that still needs to be integrated with the RSYS O-DU High code.

The F release can be used for end to end testing and it is based on the E maintenance release that was used for the 2021 November US O-RAN Plugfest and tested in conjuction with 2 stack partners and 2 different Test equipment vendors. The Front Haul Interface was also tested for compliance using Keysight's Front Haul Test equipment.

Container images and deployment instructions TBD

E Release Feature Scope: 

O-DU Low  E maintenance release was provided in March, 2022 and it is based on the code used in the November 2021 US O-RAN Plugfest. There are additional changes in the vendor specific portion of the API to support Massive MIMO and URLLC.

Since the code was deployed in the US O-RAN Plugfest using the commercial versions of the stack partners O-DU High code, the open source version from the partners need to be integrated as well. 

The validation done prior to the release used the timer-mode and the test-mac to check all the new features.

Provided O-DU Low E-Maintenance Release on March 2022 to the O-RAN gerrit repo, documentation was updated. Binary blobs for the FlexRan L1 and testmac codes were also provided in github in March.
