  Abstract: This paper studies a wireless powered communication network (WPCN) consisting of a hybrid access point (H-AP) and multiple user equipments (UEs), all of which operate in full-duplex (FD). We first propose a transceiver structure that enables FD operation of UEs to receive energy in the downlink (DL) and transmit information in the uplink (UL) simultaneously. We then provide an energy usage model in the proposed UE transceiver accounting for energy leakage from transmit chain to receive chain. It is shown that throughput of FD WPCN with the proposed FD UEs can be maximized by optimally allocating UL transmission time to UEs by solving a convex optimization problem. Simulation results reveal that the use of the proposed FD UEs efficiently improves the throughput of WPCN with practical self-interference cancellation capability at the H-AP.
