Multi-antenna has a great potential to improve the performance of wireless communication system due to its spatial multiplexing. In this paper, the authors investigate the Degrees of Freedom (DoF) of Wyner's linear asymmetric channel where each transmitter connects to its own receiver and one successive receiver. The DoF regions of Wyner's linear asymmetric channel for 2 users are provided when each node is equipped with arbitrary number of antennas. Meanwhile, the total DoF of this channel for arbitrary K users are obtained when transmitters and receivers are equipped with different number of antennas.
