I am aware that a random phase shift will be introduced by the channel, but I need a method to measure the received phase (even if it does not exactly match the one from the transmitter) and store it, so I can then run some statistics on them This is why I think that the TX and RX do not need to be phase-synchronized.
Best,

Cool :) Ah, so a multiply_const with a constant of $e^{j\frac{2\pi}{f_\text{sample}\varphi}$, yeah. Well, you can't see absolute phase without further ado – that would need your TX and RX to be phase-synchronized (you don't know the electrical length between your transmitter and receiver, it's absolutely random by itself).
