Actually, I don't know. I thought that by using PC clock in UHD sink and
source block in gnuradio allows synchronization.
Also, I thought that Schmidl and Cox algorithm used for timing recovery in OFDM
receivers.

Any OFDM receiver needs a timing recovery method anyways, so that has nothing
to do with
how well your PC is suitable for synchronizing two devices.
