N2 - We consider the time-correlated multiple-antenna interference channel where the transmitters have (i) delayed channel state information (CSI) obtained from a feedback channel as well as (ii) imperfect current CSIT, obtained e.g., from prediction on the basis of these past channel samples. We derive the degrees of freedom region for the two-user MISO interference channel under such conditions. In doing so we propose an optimal scheme relying on a form of space-time alignment combined with interference quantization. Extensions to some MIMO cases are also considered1.
