In recent years, a number of ingenious techniques have been proposed to deal with delayed and imperfect CSIT. However, the precise DoF impact of these techniques depends heavily on the channel model. We consider the use of linear Finite Rate of Information (FRoI) signals to model time-selective channel (FRoIC) coefficients. FRoIC models allow compressed feedback (FB) and capture the DoF of the channel coefficient time series. Both block fading model and stationary bandlimited channel models are special cases thereof. The FroIC model allows Foresighted Channel FB (FCFB), which keeps the DoF unaffected in the presence of CSIT FB delay. The FRoIC model with multiple basis functions accommodates FB delay beyond the coherence time and handling of users with unequal coherence times.
