Demand response (DR) has been widely regarded as an effective way to provide regulation
services for smart grids by controlling demand-side resources via new and improved …

Massive multiple-input multiple-output (MIMO) wireless communications refers to the idea
equipping cellular base stations (BSs) with a very large number of antennas, and has been …

Cognitive radio (CR) is the enabling technology for supporting dynamic spectrum access:
the policy that addresses the spectrum scarcity problem that is encountered in many …

Cognitive radio (CR) can successfully deal with the growing demand and scarcity of the
wireless spectrum. To exploit limited spectrum efficiently, CR technology allows unlicensed …

Characterizing the fundamental tradeoffs for maximizing energy efficiency (EE) versus
spectrum efficiency (SE) is a key problem in wireless communication. In this paper, we …

This article provides an overview of the state-of-art results on communication resource
allocation over space, time, and frequency for emerging cognitive radio (CR) wireless …

In this paper, we introduce a new spatial spectrum-sharing strategy for massive multiple-
input multiple-output (MIMO) cognitive radio (CR) systems. Different from the conventional …

In this paper, we present a vision beyond the conventional Long Term Evolution Fourth
Generation (LTE-4G) evolution path and suggest that time division duplexing (TDD) could …

In this paper, we consider an intelligent reflecting surface (IRS)-assisted cognitive radio
system and maximize the secondary user (SU) rate by jointly optimizing the transmit power …

To support large-scale deployment of unmanned aerial vehicles (UAVs) in the future, a new
wireless communication paradigm, namely, cellular-connected UAV, has recently received …
