Throughput Maximization for Full Duplex Wireless Powered Communication Networks [PDF]

ICC 2020 - 2020 IEEE International Conference on Communications (ICC), 2020
In this paper, we consider a full duplex wireless powered communication network where multiple users with RF energy harvesting capabilities communicate to a hybrid energy and information access point. An optimization framework is proposed with the objective of maximizing the sum throughput of the users subject to energy causality and maximum transmit ...

Relay Selection, Scheduling, and Power Control in Wireless-Powered Cooperative Communication Networks [PDF]

IEEE Transactions on Wireless Communications, 2020
Relay nodes are used to improve the throughput, delay and reliability performance of energy harvesting networks by assisting both energy and information transfer between information nodes and access point. Previous studies on radio frequency energy harvesting networks are limited to single source single/multiple relay networks.

Full-Duplex Wireless-Powered Communication Network With Energy Causality [PDF]

IEEE Transactions on Wireless Communications, 2015
In this paper, we consider a wireless communication network with a full-duplex hybrid access point (HAP) and a set of wireless users with energy harvesting capabilities. The HAP implements the full-duplex through two antennas: one for broadcasting wireless energy to users in the downlink and one for receiving independent information from users via time-
