In next-generation networks (NGN), a very large number of devices and applications are
emerged, along with the heterogeneity of technologies, architectures, mobile data, etc., and …

We consider the cell-free massive multiple-input multiple-output (MIMO) downlink, where a
very large number of distributed multiple-antenna access points (APs) serve many single …

Mobile edge computing (MEC) is an emerging computing paradigm for enabling low-
latency, high-bandwidth and agile mobile services by deploying computing platform at the …

This article investigates the downlink communications of intelligent reflecting surface (IRS)
assisted non-orthogonal multiple access (NOMA) systems. To maximize the system …

This article proposes a novel framework of resource allocation in multi-cell intelligent
reflecting surface (IRS) aided non-orthogonal multiple access (NOMA) networks, where an …

This paper proposes a multi-agent double deep Q network (DDQN)-based approach to
jointly optimize the beamforming vectors and power splitting (PS) ratio in multi-user multiple …

This article studies the resource allocation for intelligent reflecting surface aided vehicular
communications based on slowly varying large-scale fading channel information. To meet …

Precoding design for maximizing weighted sum-rate (WSR) is a fundamental problem for
downlink of massive multi-user multiple-input multiple-output (MU-MIMO) systems. It is well …

We investigate the spectral efficiency of full-duplex small cell wireless systems, in which a
full-duplex capable base station (BS) is designed to send/receive data to/from multiple half …

This paper studies a cell-free massive multiple-input multiple-output (MIMO) system where
its access points (APs) and users are equipped with multiple antennas. Two transmission …
