Properness and feasibility conjecture. A MIMO interference network is IA feasible only if it is proper.

Consider a $G$-cell, $K$-user-per-cell cellular network with antenna ratio $\gamma$, and exclude the two exceptional cases … Let $\gamma_l$ and $\gamma_r$ be the intersection point…

Consider a $G$-user interference channel, with antenna ratio $\gamma$ and threshold $\gamma_l$ as defined in the source. Let sDoF denote the normalized degrees of freedom, and let…

Let $\gamma$ denote the antenna ratio in the considered MIMO interference channel, and let the decomposition-based approach be the beamforming construction discussed in the source.…

Consider the three-user MIMO interference channel and its degrees-of-freedom (DoF) outer bound. In the cases where the outer-bound value is fractional, symbol extensions can make t…

Consider a $3K$-user interference channel with $K otinmathbb{Z}^+$? No: let $Kinmathbb{Z}^+$, and partition the transmitter–receiver pairs into groups $G1,G2,ldots,GK$, each contai…

In a MIMO interference network, let active users and secondary users be separated by pre-aligning the interference caused by the secondary transmitters at the active receivers and…
