We combine available constraints on the local [C II] 158 mu m line luminosity function from galaxy observations (Hemmati et al. 2017), with the evolution of the star formation rate density and the recent [C II] intensity mapping measurement in Pullen et al. (2018, assuming detection), to derive the evolution of the [C II] luminosity-halo mass relation over z similar to 0-6. We develop convenient fitting forms for the evolution of the [C II] luminosity-halo mass relation and forecast constraints on the [C II] intensity mapping power spectrum and its associated uncertainty across redshifts. We predict the sensitivities to detect the power spectrum for upcoming PIXIE-, STARFIRE-, EXCLAIM-, CONCERTO-, TIME-, and CCAT-p-like surveys, as well as possible future intensity mapping observations with the ALMA (Atacama Large Millimetre Array) facility.
