The goal of this work is to provide an information-theoretic characterization of the potential gains offered by Coordinated Multi-Point (CoMP) transmission in interference networks. We assume that each user’s message can be available at more than one transmitter in the network. The selection of a message assignment reflects the setup of backhaul links in a cellular downlink scenario. Given limited backhaul capacity, optimal message assignment and transmission scheme are analyzed in interference networks with full and partial connectivity. We realize in this line of work that conclusions differ dramatically based on network topology. In the last part of this work, we consider dynamic interference networks where average performance is maximized for a network with changing topology.
