comment Asymptotic variance for partial sum of a stationary process
I guess you want to avoid degenerate cases like $X_j=X_0$ for each $j$. If you assume that the sequence is $\rho$-mixing, then $V_n=n\cdot h(n)$ fo some slowly varying function. In general, there are conditions on the spectral density of the sequence, see for instance the papers by Deligiannidis and Utev.

Maybe the paper sciencedirect.com/science/article/pii/S0304414997001026 by Arcones can be useful.
