Question about using OAI L2 instead of TestMAC with RU Emulator and cuPHY Controller

Accelerated Computing Aerial Forum

Hello,

I have successfully set up and verified the RU Emulator, cuphycontroller, and TestMAC on a GH200 server using cuBB 25-3.

I would like to ask whether it is possible to use OAI L2 instead of TestMAC with the RU Emulator and cuphycontroller combination.

Specifically, I am referring to the OAI Aerial gNB configuration located under:

openairinterface5g/ci-scripts/yaml_files/sa_gnb_aerial

Is this combination officially supported or expected to work with cuBB 25-3?

If it is supported, are there any additional configuration steps, integration requirements, or known limitations compared to using TestMAC?

Thank you.

Hi @jinwoomoon ,

RU emulator cannot be used with OAI L2 because RU emulator sends data from the test vectors that are defined in a launch pattern. It works with testMAC only.

Thank you.
