Achievable Outage Rate Regions for the MISO Interference Channel
We consider the slow-fading two-user multiple-input single-output (MISO)
interference channel. We want to understand which rate points can be achieved,
allowing a non-zero outage probability. We do so by defining four different
outage rate regions. The definitions differ on whether the rates are declared
in outage jointly or individually and whether the transmitters have
instantaneous or statistical channel state information (CSI). The focus is on
the instantaneous CSI case with individual outage, where we propose a
stochastic mapping from the rate point and the channel realization to the
beamforming vectors. A major contribution is that we prove that the stochastic
component of this mapping is independent of the actual channel realization.Comment: Accepted for publication in IEEE Wireless Communications Letter
