Changing SCS from 30 kHz to 15 kHz

[praghur]

Hello all.

I am using x310 as gNB for my system. I had initially set up the configuration file for a SCS of 30 kHz. However, now when I want to test the system with SCS of 15 kHz, I am having some trouble with it. I changed the parameter to common_scs: 15.

After that, I am getting an error
--== srsRAN gNB (commit 4ac5300) ==--

Common SCS 15kHz is not equal to SSB SCS 30kHz. Different SCS for common and SSB is not supported.
srsRAN ERROR: Invalid configuration detected.

I found ssb_scs under mobility but when I added in the configuration file, it is unable to parse the code. Please see attached gnb configuration code.

mobility: 
  cells:                                      
   - ssb_scs:  15  

--== srsRAN gNB (commit 4ac5300) ==--

INI was not able to parse mobility.++
Run with --help for more information.

I am using srsran_project (commit: 4ac5300). Can you please let me know under which section should I add the ssb_scs? If there is a better way to do this, I would like to know that too.

Thanks a lot in advance.
