This work studies the sum degrees of freedom (DoF) of the asymmetric four-user MIMO Y
channel, where each user i, for 1≤ i≤ 4, is equipped with Mi antennas, and the relay is …

In this paper, we study the degrees of freedom (DoF) region for the multiple-input multiple-
output two-way X relay channel with asymmetric antenna setting. In this channel model …

The K-user multiple input multiple output (MIMO) Gaussian symmetric interference channel
where each transmitter has M antennas and each receiver has N antennas is studied from a …

The K-user MIMO Y-channel consisting of K users which want to exchange messages
among each other via a common relay node is studied in this paper. A transmission strategy …

To address the coverage and capacity challenges in fifth-generation (5G) wireless networks,
the relay technique has been considered as a promising solution and recently attracted …

In this paper, bi-directional communication between K node pairs is considered. Each node
has N antennas and wants to transmit d data streams to its communication partner. Q relays …

This work is to study the degrees of freedom (DoF) of the K-user MIMO Y channel.
Previously, two transmission frameworks, in addition to the original signal alignment …

In this paper, we study the amplify-and-forward (AF) relaying based signaling scheme for the
Y channel consisting of three single-antenna users and a two-antenna relay. In such a …

We design a new improved signal space alignment scheme in MIMO Y channel where one
of K source nodes sends K− 1 independent messages to the other nodes and each …

This paper investigates the degrees of freedom (DoF) of the two-cluster multi-way relay
channel. Two cases are investigated: the case when there are 2 users in each cluster with …
