We study the degrees of freedom (DoF) of MIMO two-way X relay channels. Previous work studied the case N <; 2M, where N and M denote the number of antennas at the relay and each source, respectively, and showed that the maximum DoF of 2N is achievable when N <; ⌊8M/5⌋ by applying signal alignment (SA) for network coding and interference cancelation.
