Treating interference as noise has recently been shown to be sum capacity achieving for the two-user single-input single-output (SISO) Gaussian interference channel in a low interference regime. In this paper, we characterize the low interference regime for the multiple-input single-output (MISO) Gaussian interference channel. We also provide partial results for the general multiple-input multiple-output (MIMO) Gaussian interference channel.
