High Speed Flag for 5G

Hi Guys.

I am travelling now in the High Speed Train, up to 320 km/h.

5G signal is full.

But the 5G service in intermittent from time to time (no tunnel, coverage is continuously 5G)…

Is there any parameters like 4G called HSF (High Speed Flag) that needs to be activated and maybe tuned?

Sure.

Principles and probably names of the features are absolutely the same.

Which SCS is used?

I think at 15 kHz Doppler effect wouldn’t be critical.

What is dm-rs config?

You may need to use 3 dm-rs.
