What will the future of UAV cellular communications be? In this tutorial article, we address
such a compelling yet difficult question by embarking on a journey from 5G to 6G and …

The event-triggered sliding-mode control (SMC) for discrete-time networked Markov jumping
systems (MJSs) with channel fading is investigated by means of a genetic algorithm. In order …

We consider a cellular network deployment where UAV-to-UAV (U2U) transmit-receive pairs
share the same spectrum with the uplink (UL) of cellular ground users (GUEs). For this …

This paper is dedicated to the analysis of energy efficiency of the D2D direct connection
system in 5G networks. Fast development of 5G networks results in large increase of …

Device-to-Device (D2D) communication is one of the enabling technologies for meeting the
capacity requirements of the fifth-generation wireless systems (5G). It has diverse …

The massive amounts of machine-type user equipments (UEs) will be supported in the future
fifth generation (5G) networks. However, the potential large random access (RA) delay calls …

In this paper, we consider a vehicular network in which the wireless nodes are located on a
system of roads. We model the roadways, which are predominantly straight and randomly …

Reconfigurable intelligent surface (RIS) is a new and revolutionary technology to achieve
spectrum-, energy-and cost-efficient wireless networks. This paper studies the resource …

Emerging cellular technologies such as those proposed for use in 5G communications will
accommodate a wide range of usage scenarios with diverse link requirements. This will …

This paper investigates the fundamental issues of mode selection and spectrum partition in
cellular networks with in-band device-to-device (D2D) communication from the physical …
