description A reduced-overhead channel estimation method and system thereof for massive MIMO systems is provided in present application. The method is applied in a base station device, and includes following steps: first, enabling the base station device to acquire a plurality of channel matrixes between the base station device and one or a plurality of external user devices, then enabling the base station device to label the positions of a non-zero coefficient and a common support coefficient in a plurality of fields of the channel matrixes, and then enabling the base station device to configure the non-zero coefficient and the common support coefficient to have the weights different from the weights of the coefficients in the other fields in the channel matrixes so as to provide estimating channel matrixes.
