channels (MAC) to achieve efficient data aggregation, which is a very effective way to …

Backscatter-assisted wireless-powered relaying has emerged as a promising approach to
extend the transmission range of energy-constrained devices, eg, sensors, with improved …

In this paper, we propose a multi-hop multiple input multiple output (MIMO) decode-and-
forward relaying protocol in cognitive radio networks. In this protocol, a multi-antenna …

To address the high-performance requirements of Internet of Things (IoT) application
scenarios, we design a non-orthogonal multiple access (NOMA) assisted cognitive short …

Due to the ever-expanding applications of the Internet-of-Things (IoT), designing energy-and
spectrally-efficient transmission schemes to support massive connections and devices is …

In this paper, we propose short-packet communications (SPCs) with non-orthogonal multiple
access (NOMA) for coordinated and direct relay transmission (CDRT) Internet-of-Things …

In this work, we consider multiple energy harvesting relays to assist information transmission
from a hybrid access point (HAP) to a distant receiver. The multi-antenna HAP also …

As one of the main scenarios of 5G, Ultra Reliable Low Latency Communication (URLLC)
plays an important role in Industrial Internet of Things (IIoT) for smart factories. At present …

This paper investigates the precoder design in a multi-hop multiple-input multiple-output
(MIMO) relay system with cognitive radio. We assume that the source node (secondary user) …

In future wireless communications, the Internet of Things (IoT) is a promising paradigm
which is expected to connect massive number of devices while satisfying ultra-reliable and …
