We consider the time-correlated multiple-antenna interference channel wherethe transmitters have (i) delayed channel state information (CSI) obtained froma latency-prone feedback channel as well as (ii) imperfect current CSIT,obtained e.g. from prediction on the basis of these past channel samples. Wederive the degrees of freedom (DoF) region for the two-user multiple-antennainterference channel under such conditions. The proposed DoF achieving schemeexploits a particular combination of the space-time alignment protocol designedfor fully outdated CSIT feedback channels (initially developed for thebroadcast channel by Maddah-Ali et al, later extended to the interferencechannel by Vaze et al. and Ghasemi et al.) together with the use of simplezero-forcing (ZF) precoders. The essential ingredient lies in the quantizationand feedback of the residual interference left after the application of theinitial imperfect ZF precoder. Our focus is on the MISO setting albeitextensions to certain MIMO cases are also considered.
