Example cuphycontroller configuration for 50MHz bandwith

Accelerated Computing Aerial Forum

Hi,

I’m integrating Nvidia Aerial HighPHY with the OAI stack for L2-L3. Do you have any example configuration files or guidance for a 50MHz setup?

Thank you for your help!

Hi @thanhlong_le,

There are no configuration changes needed on cuphycontroller configuration yaml file for 50 MHz BW.

Thank you.

Hi @bkecicioglu ,

  1. Can you elaborate more how to change the bandwidth to 50MHz? Forget to mention but I am using cuBB version 24-1, does it matter? Should I change to 24-2?

  2. In my case, I only need to change the OAI configuration to 50MHz?

  4. I tried to change the SSB and PointA arfcn and UL/DL PRB to 133 and observe from the highPHY log some information:

  • [DRV.PUSCH] static_params.nMaxPrb: 273
  • [DRV.API] Update cell: mplane_id=5 dl_grid_sz=133
  • [DRV.API] Update cell: mplane_id=5 ul_grid_sz=133
    But the UP for DL still contains 273 PRB:

    What should I do to make DL UP send only 133 PRB?

Thank you

The ASDK version does not matter.

That is correct.

Please let us know if you were able to resolve this issue on your setup.

Thank you.
