Satellite internet serves as an indispensable component of the upcoming sixth-generation
networks for providing global broadband internet access service. Due to the open nature of …

Non-orthogonal multiple access (NOMA), as a well-qualified candidate for sixth-generation
(6G) mobile networks, has been attracting remarkable research interests due to high …

While the millimeter-wave (mmWave) communication is less susceptible against the
conventional wiretapping attack due to its short transmission range and directivity, this paper …

This paper investigates short-packet communications over a diamond relay network with two
untrusted relays (potential eavesdroppers) with the purpose of guaranteeing reliability and …

The massive multiple input multiple output (mMIMO) provides reliable base station (BS) for
the mobile users (MUs) with CSI (channel state information) and jointly offers spectral …

We investigate physical layer security for multi-user peer-to-peer relay networks, where a
secure user pair and other unclassified users exchange information only through a multi …

A two-untrusted-relay transmission scheme is proposed with lossy-forward (LF) relaying
being utilized. Two untrusted relays are located between one source and one common …

This paper investigates the physical layer security performance of an untrusted relay
network in the finite blocklength regime. Lossy decode-and-forward (DF) relaying is …

Increasing demand for both achieving higher data rate to solve computationally intensive
tasks timely and connecting more user equipment (UEs) simultaneously have prompted …

In this paper, we consider a two-way relay (TWR) network that two source nodes (SNs) with
multiple antennas exchange data to each other via a relay node (RN) with multiple …
