QoS Considerations for Full Duplex Multi-user MIMO Systems


A. C. Cirik, O. Taghizadeh, R. Mathar, T. Ratnarajah,


        We consider a full-duplex (FD) multi-user multiple-input multiple output (MIMO) system where the base-station (BS) serves multiple uplink (UL) and downlink (DL) users simultaneously. We address the Quality-of-Service (QoS) problem, in which the transmitted sum-power at the BS and UL users is minimized subject to minimum rate constraints at each user of the system. We first propose a centralized solution based on sequential convex programming (SCP), and then propose a distributed solution by using interference prices exchanged among the nodes to represent the cost of received interference. The proposed designs are evaluated via numerical simulations.
