Problems scanning for the cell using UE

[michalisk13]

Hi and thanks for the repo!

I have managed to build it and I am trying to run the nr-softmodem using the AntSDR U series SDR.
I am running a 20MHz cell @ n78 and a 20MHz @ n1 and my UE is unable to see the cell in both cases.

Do you suggest any configuration file that might work?

Thanks,
Mak

Hi Mak,

Thanks for reaching out and for your interest!

I’m not sure if you’ve already tested using OpenAirInterface, but I suggest trying the configuration made for the USRP B210. Here’s an example configuration file that might work for you:

openairinterface5g/targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band78.fr1.106PRB.usrpb210.conf

In my case, I used the AntSDR U220. If you check my last commit on this repo, you’ll see that I made changes to the Dockerfile because I use Docker for my research. When building locally, you need to specify -w ANTSDR instead of -w USRP.

Feel free to send me some logs if you need further assistance.

Just a note, this repo is not the latest version from OAI. I made a fork at that time and added my modifications, but these can be applied to the new version using a patch or other methods.

Best regards,
