A multiple-input multiple-output two-way relay channel consisting of two communication nodes and a full-duplex relay node is considered, assuming that no direct link exists between the two communication nodes. We propose an achievable scheme using lattice codes combined with generalized singular value decompositionbased precoding for the first phase and vertically encoded structural bining for the second phase. We show that the proposed scheme achieves the cut-set bound asymptotically as the signal-to-noise ratio tends to infinity.
