Query: Noisy-Interference Sum-Rate Capacity for Vector Gaussian Interference
  Channels   New sufficient conditions for a vector Gaussian interference channel to
achieve the sum-rate capacity by treating interference as noise are derived,
which generalize the existing results. More concise conditions for
multiple-input-single-output, and single-input-multiple-output scenarios are
obtained.
