… In the following, D(out) denotes an outer bound region to D, D(in,lin,mem) denotes the
achievable DoF region when the IR is restricted to use our memoryless linear processing on its …

… on the DoF compared to the case where there is no relay. The proposed cooperative … DoF
of the rank-deficient MIMO relay IC. Let 𝑅(𝑃) denote an achievable sum rate of this channel…

… In this paper not only we study the achievable DoF region of the general (M,N,L) case but,
as opposed to [18], we also provide outer bounds. Our main contribution is two-folded. First we …

… of the DoF region of the symmetric channel, we … the DoF is achievable by considering each
dominant term in the above expression. Moreover, we compare the achievable weighted-DoF …

… Our results explicitly reveal that the achievable sum DoF can still be better than that in single-…
We term this scheme CXR (cascaded X channel relaying) in the remainder of the paper. To …

… DoF dΣ of the channel as the maximum achievable total DoF … that no DoF tuple outside DK
is achievable, we derive a DoF … Y-channel into an N × (K − 1)M MIMO point-to-point channel […

… -DoF is achievable for the K-way relay channel where all nodes have M = K − 1 antennas.
This is shown by a new achievable … sum-DoF for the MIMO Gaussian K-way relay channel is …

… of channel distributions, we show an achievable DoF region … Gaussian relay networks, which
characterizes the optimal DoF … AF relaying scheme and derive its achievable DoF region for …

… DoF expression and IA feasibility are also quite challenging. The effect of the relays on the
DoF of the K-user interference channel is … and the achievable DoF of the proposed scheme. …

… In this section, we investigate the achievable DOF in the asymmetrical multi-way relay channel
without direct links between the UEs and the BS. We first summarize the main result in the …
