[srsran-users] external clock for UE needed?

[oiu13q2t5pibtq1]

https://docs.srsran.com/projects/project/en/latest/user_manuals/source/1_getting_started.html

states:

> If you plan to connect the gNB to a COTS UE we recommend that you use an external clock source such as an Octoclock of GPSDO that is compatible with your RF-frontend, as the on-board clock within the USRP is not accurate enough to enable a connection with the UE. This is discussed further in the relevant app note.

And here: https://docs.srsran.com/projects/4g/en/latest/app_notes/source/5g_sa_COTS/source/index.html

its stated:

> If you encounter issues with the phone not finding the cell and/or not being able to stay connected it might be due to inaccurate clocks at the gNBs RF frontend. Try to use an external 10 MHz reference or use a GPSDO-disciplined oscillator.

So do I only need an external clock for eNB/gNB nodes or would I also use one for UE operations?
