In this paper, we study (G, α)-frames for finite dimensional Hilbert spaces, where G is a finite group and α is a unitary Schur multiplier of G. We apply the characterizations for tight (G, α)-frames and central (G, α)-frames to investigation of (G, α)-frames that have the maximal spanning property. We apply the theory of twisted group frames to obtain a criterion for maximal spanning vectors that generalizes the main result of [16, Theorem 1.7]. Moreover, we prove that a projective representation does not admit any maximal spanning vector if it has an at least 2-dimensional subrepresentation that is equivalent to a central projection induced subrepresentation of the α-regular representation.
