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 …

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 …

For two-hop amplify-and-forward (AF) multiple-input multiple-output (MIMO) relay systems,
the uplink-downlink duality has been recently investigated. In this paper, we establish the …

In this letter, we investigate the achievable degrees of freedom (DoF) of four-user MIMO Y
channel where four users each with M antennas intend to exchange messages via a relay of …

In this letter, we introduce a new system model for a multi-way communication where
multiple users exchange information with each other by sharing an intermediate relay with …

In this paper, we study achievable degrees of freedom (DoF) of a multiple-input multiple-
output (MIMO) multiway relay channel (mRC) where K users, each equipped with M …

In this paper, we propose a new three-user network information flow model, referred to as
the triangular multiple-input-multiple-output (MIMO) relay (TMR) channel, which consists of …

We consider the one-way relay aided MIMO X fading Channel where there are two
transmitters and two receivers along with a relay with M antennas at every node. Every …

We investigate a joint design of linear precoders and receivers for multiple-input multiple-
output non-simultaneous two-way relaying (NS-TWR). Unlike conventional two-way …

In conventional two-way relaying (TWR), it is assumed that a user has data to send and
receive simultaneously from the base station (BS) via a relay. In cellular systems, data flow …
