Query: Aligned Image Sets and the Generalized Degrees of Freedom of Symmetric
  MIMO Interference Channel with Partial CSIT   The generalized degrees of freedom (GDoF) of the two user symmetric multiple
input multiple output (MIMO) interference channel (IC) are characterized as a
function of the channel strength levels and the level of channel state
information at the transmitters (CSIT). In this symmetric setting, each
transmitter is equipped with M antennas, each receiver is equipped with N
antennas, and both cross links have the same strength parameter $\alpha$ and
the same channel uncertainty parameter $\beta$. The main challenge resides in
the proof of the outer bound which is accomplished by a generalization of the
aligned image sets approach.
