ACHIEVING THE DEGREES OF FREEDOM FOR THE TWO-CELL MIMO INTERFERING BROADCAST CHANNELS WITH LIMITED FEEDBACK
Abstract
We consider the two-cell MIMO interfering broadcast channel (IBC) with $K$ users assigned to each base station, and we develop two closely-related Interference Alignment schemes that are well suited to a limited feedback implementation. The schemes are developed for BSs with $K+1$ antennas and receivers with $K$ or $K+1$ antennas, respectively. The schemes achieve the maximum degrees of freedom (DoF), $2 K$, and are shown to have a smaller …
