As a low-cost and low-power-consumption passive reflector, intelligent reflecting surface
(IRS) can make a significant rate improvement by building a programmable wireless …

One of the major challenges the mobile broadband community faces is the exponential
increase in mobile data traffic, even more so, for cell‐edge users. Thus, in a multitier …

Ever since the wireless relay network (RN) was introduced, it has led to the discovery of
several new protocols, which have been consistently improved by researchers to overcome …

In this paper, we develop a non-orthogonal multiple access (NOMA)-based multi-pair two-
way relay (TWR) network, in which a rate splitting scheme and a successive group decoding …

Two-way relaying has demonstrated significant gain in spectral efficiency by applying
network coding when a pair of source nodes exchange information via a relay node. This …

This paper investigates the degrees of freedom (DoF) of the L-cluster, K-user MIMO multiway
relay channel, where users in each cluster wish to exchange messages within the cluster …

Two-way relaying can improve spectral efficiency in two-user cooperative communications. It
also has great potential in multiuser systems. A major problem of designing a multiuser two …

We consider a scenario where multiple pairs of users exchange information within pair, with
the help of a dedicated multi-antenna relay. The protocol integrates the idea of analogue …

This paper addresses joint transceiver and relay design for a wireless multiple-input multiple-
output (MIMO) switching scheme that enables data exchange among multiple users. Here, a …

We study the degrees of freedom (DOF) of a multiple-input multiple-output (MIMO) two-way
X relay channel, where there are two groups of source nodes and one relay node, each …
