In this paper, the authors consider max-min fairness for wireless energy transfer in a downlink multiuser communication system. Their resource allocation design maximizes the minimum harvested energy among multiple multiple-antenna energy harvesting receivers (potential eavesdroppers) while providing Quality of Service (QoS) for secure communication to multiple single antenna information receivers. In particular, the algorithm design is formulated as a non-convex optimization problem which takes into account a minimum required Signal-to-Interference-plus-Noise Ratio (SINR) constraint at the information receivers and a constraint on the maximum tolerable channel capacity achieved by the energy harvesting receivers for a given transmit power budget.
