Harvesting management in multiuser MIMO systems with simultaneous wireless information and power transfer

In this paper, we focus on a broadcast multiuser multiple-input multiple-output (MIMO) system where we consider that some terminals harvest power and, thus, recharge their batteries through wireless power transfer from the transmitter, while others are simultaneously being served with data transmission. The weighted sum-rate of the terminals that are receiving information data is considered as the optimization policy where minimum energy harvesting constraints are taken into account. We propose a procedure for managing the minimum energy to be harvested by the terminals considering the effect in the target system performance.Peer Reviewe
