  This paper studies two power control problems in energy harvesting wireless
networks where one hybrid base station (HBS) and all user equipments (UEs) are
operating in in-band full-duplex mode. We consider minimizing the aggregate
power subject to the quality of service requirement constraint, and maximizing
the aggregate throughput. We address these two problems by proposing two
distributed power control schemes for controlling the uplink transmit power by
the UEs and the downlink energy harvesting signal power by the HBS. In our
proposed schemes, the HBS updates the downlink transmit power level of the
energy-harvesting signal so that each UE is enabled to harvest its required
energy for powering the operating circuit and transmitting its uplink
information signal with the power level determined by the proposed schemes. We
show that our proposed power control schemes converge to their corresponding
unique fixed points starting from any arbitrary initial transmit power. We will
show that our proposed schemes well address the stated problems, which is also
demonstrated by our extensive simulation results.
