uMAT–MAT gap conjecture. For the same scenario, the DoF gap defined above holds for any number of cells $C$.

uMAT scaling conjecture. Based on the experimental results, the same asymptotic DoF-gap behavior is valid for an arbitrary number of cells $C$.

Consider the 2-transmitter 2-receiver network setting of the paper's linear-subspace-ratio lemma. Let $n\in\mathbb N$, let $\{f_1^{(n)},f_2^{(n)}\}$ be arbitrary encoding functions…

The $X$-channel has two transmitters and two receivers, with channel-state information at the transmitters available only with delay. Its total degrees of freedom are the sum rate…

Let the $K$-user interference channel and the $S\times K$ X channel operate with delayed channel-state information at the transmitters (delayed CSIT), and let $K$ denote the number…
