报告摘要

We study the degrees of freedom (DoF) regions of two-user multiple-input multiple-output (MIMO) Z and full interference channels in this paper. We assume that the receivers always have perfect channel state information. We derive the DoF region of Z interference channel with channelstate information at transmitter (CSIT). For full interference channel without CSIT, the DoF region has been obtained in previous work except for a special case M_1<N_1<min(M_2,N_2), where M_i and N_i are the number of transmit and receive antennas of user i, respectively. We show that for this case the DoF regions of the Z and full interference channels are the same. We establish the achievability based on the assumption of transmitter antenna mode switching. We also present a systematic way of constructing the DoF-achieving nulling and beamformingmatrices.
