The authors consider the application of Interference Alignment (IA) to the cellular case with constant MIMO channel coefficients. Neglecting the weakest interferers in the network, they introduce an algorithm to obtain a partially connected (in particular, L-interfering) network, over which the feasibility of IA can be analyzed simply. They consider the application of IA over the obtained L-interfering network, while the rest of the interference is treated as noise. They benchmark this technique through extensive Monte-Carlo simulations, and introduce an approximate, compact expression for the ergodic mutual information achievable in the considered network setting.
