Throughput maximization in wireless powered communication networks [PDF]
2013 IEEE Global Communications Conference (GLOBECOM), 2013 This paper studies the newly emerging wireless powered communication network (WPCN) in which one hybrid access point (H-AP) with constant power supply coordinates the wireless energy/information transmissions to/from distributed users that do not have energy sources.

Full-Duplex Operations in Wireless Powered Communication Networks [PDF]
ETRI Journal, 2017 In this paper, a wireless powered communication network (WPCN) consisting of a hybrid access point (H-AP) and multiple user equipment (UEs), all of which operate in full-duplex (FD), is described. We first propose a transceiver structure that enables FD operation of each UE to simultaneously receive energy in the downlink (DL) and transmit information ...

Network Efficient Power Control for Wireless Communication Systems [PDF]
The Scientific World Journal, 2014 We introduce a two-loop power control that allows an efficient use of the overall power resources for commercial wireless networks based on cross-layer optimization. This approach maximizes the network’s utility in the outer-loop as a function of the averaged signal to interference-plus-noise ratio (SINR) by considering adaptively the changes in the ...
