Uplink Time Scheduling With Power Level Modulation Scheme in Wireless Powered Communication Networks

IEEE Access, 2019
In this paper, we propose an uplink scheduling scheme via downlink signal design for wireless powered communication networks (WPCNs). Although harvest-then-transmit protocols and related optimal resource allocation problems were studied, explicit methods

Throughput Maximization for RIS-Assisted UAV-Enabled WPCN

IEEE Access
This paper investigates a reconfigurable intelligent surface (RIS)-assisted unmanned aerial vehicle (UAV)-enabled wireless powered communication network (WPCN). In the system, a UAV acts as a hybrid access point (HAP) to charge users in the downlink (DL)

Short packet communication in IoT networks: performance analysis

Journal of Information and Telecommunication
In this paper, we investigated the block error rate (BLER) performance of a wireless powered communication network (WPCN) employing short packet communication (SPC). In this system, a source node harvests energy from a dedicated power beacon and utilizes
