In order to study a class of finite-dimensional representations of Uq(sl2), we deal with the quotient algebra Uq (m, n, b) of quantum group Uq(sl2) with relations Kr=1, Emr=b, Fnr=0 in this paper, where q is a root of unity. The algebra Uq(m, n, b) is decomposed into a direct sum of indecomposable (left) ideals. The structures of indecomposable projective representations and their blocks are determined.
