I am reading about CFO estimation in OFDM system, assume for example that we estimate it based on CP as mentioned HERE and the estimated CFO for the received signal $r(t)$ is $β$. My question, how now can we compensate that CFO on the time-domain signal $r(t)$ ?

As with any signal: multiply with an appropriate $e^{-j2\pi \beta n}$.

(That, by the way, directly results from the last line of the answer you've linked to.)
