The commercial fifth-generation (5G) wireless communications networks have already been
deployed with the aim of providing high data rates. However, the rapid growth in the number …

Long-range (LoRa) technology is most widely used for enabling low-power wide area
networks (WANs) on unlicensed frequency bands. Despite its modest data rates, it provides …

Full-duplex (FD) wireless technology enables a radio to transmit and receive on the same
frequency band at the same time, and it is considered to be one of the candidate …

This paper presents novel ultrareliable and low-latency communication (URLLC) techniques
for URLLC services, such as Tactile Internet services. Among typical use cases of URLLC …

Unmanned aerial vehicle (UAV) wireless communication has recently been recognized to
be inevitable and prevalent in the fifth-generation (5G) wireless networks. In this paper, we …

Aerial vehicles (AVs) such as electric vertical take-off and landing (eVTOL) aircraft make
aerial passenger transportation a reality in urban environments. However, their …

In this paper, we propose a novel wireless architecture, mounted on a high-altitude aerial
platform, which is enabled by reconfigurable intelligent surface (RIS). By installing RIS on …

Researchers for the third-generation partnership project (3GPP) have been exploring—as a
cost-effective alternative to wired backhaul—integrated access and backhaul (IAB) …

Owing to the superior performance in spectral efficiency, connectivity, and flexibility,
nonorthogonal multiple access (NOMA) is recognized as the promising access protocol and …

Due to the practical challenges in the deployment of existing half-duplex systems, the
promise of ubiquitous backscatter connectivity has eluded us. To address this, we design the …
