Densification of network base stations is indispensable to achieve the stringent Quality of
Service (QoS) requirements of future mobile networks. However, with a dense deployment of …

The mobile data traffic has been exponentially growing during the last several decades. This
was enabled by the densification of the network infrastructure in terms of increased cell …

Imagine a coverage area where each mobile device is communicating with a preferred set of
wireless access points (among many) that are selected based on its needs and cooperate to …

Multiple antenna technologies have attracted much research interest for several decades
and have gradually made their way into mainstream communication systems. Two main …

Imagine a coverage area with many wireless access points that cooperate to jointly serve
the users, instead of creating autonomous cells. Such a cell-free network operation can …

Cell-free Massive MIMO is considered as a promising technology for satisfying the
increasing number of users and high rate expectations in beyond-5G networks. The key idea …

Cell-free (CF) massive multiple-input-multiple-output (MIMO) systems have a large number
of individually controllable antennas distributed over a wide area for simultaneously serving …

This paper proposes a novel scheme for cell-free massive multiple-input multiple-output
(CFmMIMO) networks to support any federated learning (FL) framework. This scheme allows …

Cell-free Massive MIMO (multiple-input multiple-output) is a promising distributed network
architecture for 5G-and-beyond systems. It guarantees ubiquitous coverage at high spectral …

In future cell-free (or cell-less) wireless networks, a large number of devices in a
geographical area will be served simultaneously in non-orthogonal multiple access …
