Equiangular lines in $\mathbb{C}^d$.

Question

Zauners' conjecture regarding equiangular lines for any $\mathbb{C}^{d}$ , holds for many dimesnions, like 17 or more(43, 31, and so on). This conjecture gives the number of equiangular lines in a given complex space $\mathbb{C}^d$. A similar result shows that for Euclidean spaces, given an angle, the number of equiangular lines can be found, result here this result is for the case of a given angle, finding the number of equiangular lines like in Zauners' conjecture (over $\mathbb{C}^{d}$), but for a given angle. Is there a number(it could be a lower/upper bound, or like Zauners' conjecture - exact), but with the constraint that it is for a given angle over $\mathbb{C}^{d}$?
