D2D Communications Underlaying Wireless Powered Communication Networks
IEEE Transactions on Vehicular Technology, 2018 In this paper, we investigate the resource allocation problem for D2D communications underlaying wireless powered communication networks, where multiple D2D pairs harvest energy from a power station equipped with multiple antennas and then transmit information signals simultaneously over the same spectrum resource.

Wireless Powered Communication Networks Using Peer Harvesting [PDF]
IEEE Access, 2017 For an energy-constrained wireless network, energy harvesting (EH) is a promising technology to prolong the network life. Whether traditional near-field wireless power transfer (WPT) using inductive and resonant coupling or far-field WPT via radiated electromagnetic waves, both of them draw considerable research interests these years [1], [2].

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 ...

Slotted ALOHA for Wireless Powered Communication Networks
IEEE Access, 2018 Centralized controls in wireless-powered communication networks (WPCNs) induce considerable overhead for channel estimation and high complexity for optimization, as the number of wireless devices (WDs) increases. To tackle this problem, we apply slotted ALOHA protocol to WPCNs and design a slotted ALOHA-based energy-harvesting medium access control ...

Wireless Powered Communication Networks With Non-Ideal Circuit Power Consumption [PDF]
IEEE Communications Letters, 2017 Assuming non-ideal circuit power consumption at the energy harvesting (EH) nodes, we propose two practical protocols that optimize the performance of the harvest-then-transmit wireless powered communication networks (WPCNs) under two different objectives: (1) proportional fair (PF) resource allocation, and (2) sum rate maximization.
