In this book, we discuss NOMA and the various issues in NOMA networks, including
capability, sustainability, and security. This book starts from the basics and key techniques of …

In this paper, energy efficient resource allocation is considered for an uplink hybrid system,
where non-orthogonal multiple access is integrated into orthogonal multiple access (OMA) …

Non-orthogonal multiple-access (NOMA) has recently been proposed to improve throughput
and spectrum-efficiency of 5G cellular networks and beyond. It is also a key enabler for ultra …

The future generation of wireless communication networks demands for high spectral
efficiency to accommodate a large number of devices over the limited available frequency …

In a heterogeneous cellular network (HetNet), consider that a base station in the HetNet is
able to simultaneously schedule and serve K users in the downlink by performing the power …

This paper focuses on resource allocation in energy-cooperation enabled two-tier
heterogeneous networks (HetNets) with non-orthogonal multiple access (NOMA), where …

Nonorthogonal multiple access (NOMA) systems are vulnerable to jamming attacks,
especially smart jammers who apply programmable and smart radio devices such as …

Narrowband Internet of Things (NB-IoT) provides energy-efficient communications with
extended coverage for the low data rate IoT devices. In this paper, we propose a power …

For the future sixth-generation (6G) wireless communication networks, improved metrics are
expected to provide connectivity of massive devices, which brings new challenges for 6G …

This paper investigates the resource allocation problem in vehicular communications based
on multi-agent Deep Deterministic Policy Gradient (DDPG), in which each Vehicle-to …
