An Adaptive Transmission Protocol for Wireless-Powered Cooperative Communications
Yifan Gu, He Chen, Yonghui Li, Branka Vucetic

TL;DR
This paper introduces an adaptive transmission protocol for wireless-powered cooperative networks where devices harvest energy from RF signals before transmitting, optimizing communication strategies based on channel conditions to improve throughput.
Contribution
The paper proposes a novel adaptive transmission protocol that dynamically selects between direct and cooperative transmission based on channel state information in wireless-powered networks.
Findings
The proposed AT protocol significantly outperforms HTT and HTC protocols in throughput.
Derived an approximate closed-form expression for average throughput over Nakagami-m fading.
Simulation results verify the effectiveness of the adaptive protocol.
Abstract
In this paper, we consider a wireless-powered cooperative communication network, which consists of one hybrid access point (AP), one source and one relay to assist information transmission. Unlike conventional cooperative networks, the source and relay are assumed to have no embedded energy supplies in the considered system. Hence, they need to first harvest energy from the radio-frequency (RF) signals radiated by the AP in the downlink (DL) before information transmission in the uplink (UL). Inspired by the recently proposed harvest-then-transmit (HTT) and harvest-then-cooperate (HTC) protocols, we develop a new adaptive transmission (AT) protocol. In the proposed protocol, at the beginning of each transmission block, the AP charges the source. AP and source then perform channel estimation to acquire the channel state information (CSI) between them. Based on the CSI estimate, the AP…
