Sum-Power Minimization Under Rate Constraints in Full-Duplex MIMO Interference-Channels


A. C. Cirik, O. Taghizadeh, A. Liu, L. Lampe, R. Mathar,


        We consider a full-duplex (FD) multiple-input multiple-output (MIMO) interference-channel, where multiple pairs of FD nodes coexist in the same network, and hence each node not only suffers from self-interference due to operating in FD mode, but also from co-channel-interference (CCI) from other pairs due to simultaneous transmission at each link. Transmission power expenditure is a significant source for power consumption in communication systems. One way to extend battery life is to utilize power-efficient resource allocation that minimizes the transmit power minimization. Therefore, in this paper we propose a penalty-based algorithm to address the Quality-of-Service (QoS) issue of this FD system where the total transmit power is minimized subject to minimum rate constraints at each node. The algorithm exploits both spatial and temporal freedoms of the beamforming/source covariance matrices of MIMO links between the nodes to achieve a lower total system power
