We consider a massive multiple-input multiple-output (mMIMO) two-way decode-and-
forward (DF) relaying system with underlaid device-to-device (D2D) users. The mMIMO relay …

This paper proposes a novel cognitive cooperative transmission scheme by exploiting
massive multiple-input multiple-output (MMIMO) and non-orthogonal multiple access …

In this paper, we investigate the outage performance of a decode-and-forward (DF) underlay
cognitive two-way relay system with direct link using time division broadcast protocol in the …

In this paper, we consider the weighted sum-rate (WSR) maximization problem in a cognitive
relaying network under imperfect channel state information (CSI). The secondary network …

This work is related to ultra-reliable and low latency communication (URLLC) in Internet-of-
Thing (IoT) networks. In particular, we consider a multi-device IoT network performing blind …

Internet of Things (IoT) is one of the key applications of 5G, and the data transmission is the
basis of IoT networks. In this paper, we investigate the data transmission scheme in non …

In this study, we investigate multihop multiple-input multiple-output (MIMO) full-duplex relay
(FDR) networks with short-packet ultra-reliability and low-latency communications (uRLLCs) …

Several works have studied relaying in cognitive radio networks in terms of outage
probability. The main challenge in such works is finding a mathematical expression for this …

Intelligent reflecting surface (IRS) is a promising 6G technology that can improve wireless
communication capacity in a cost-effective and energy-efficient manner, by adjusting a large …
