In this paper, the authors develop linear Interference Alignment (IA) approach for Multi-Input-Multi-Output Interference Broadcast Channel (MIMO-IBC). Since multiple data streams from each Base Station (BS) to multiple Mobile Stations (MSs) experience identical channel, it is hard to ensure the rank constraint to the intended MSs in the desired cell meanwhile ensure the interference aligned at the unintended MSs in other cells. Considering the difficulty in aligning interference at the receiver in MIMO-IBC, they design a transceiver to align and eliminate the interference at the transmitter.
