[srsran-users] Running Multiple Cells on Same USRP

[Jon Schroeder]

Hello Everyone,

I am attempting to run multiple instances of srsENB on the same USRP B200
on different frequencies but am running into a few issues.

I am using srsRAN release 22.10 with default epc configuration. eNB and ue
files configured to support multiple cells. I modified these files to
exactly match those shown on the Carrier Aggregation page of the
documentation. I then modified their dl_earfcn values to specify our
desired frequencies. (As a note I am not trying to do carrier aggregation,
I am just trying to create two standalone eNB on the same radio).

I am able to successfully run the program and everything appears to be
working on the software end of things. However, when I use a spectrum
analyzer, I am only able to see activity from the RF1 channel of the USRP.
There is no signal from the other channel.

Does anyone have a fix for this? Is something like this possible with srs?
Thank you all for your help.

- Jon
