International audience ; This letter investigates radio resource allocation forsimultaneous wireless information and power transfer between afull-duplex (FD) multiantenna access point (AP) and multiplehalf-duplex (HD) single-antenna energy harvesting (EH) userequipment devices (UEs). The EH model of an advanced multistagerectifier circuit design is derived and used for radio resourceallocation. To account for both downlink (DL) and uplink (UL)traffic for each of the HD UEs, alternating DL and UL communicationphases between two UE groups are considered. We usethe weighted minimum mean squared error approach to developan iterative algorithm to maximize the system sum rate, utilizingoptimal receive and transmit beamformers.
