Towards a fully connected intelligent digital world, 5G and beyond networks experience a
new era of Internet of intelligence with connected people and things. This new era brings …

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 …

In this paper, we investigate the impact of channel aging on the performance of cell-free (CF)
massive multiple-input multiple-output (MIMO) systems with both spatial correlation and pilot …

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 …

The recently commercialized fifth-generation (5G) wireless networks have achieved many
improvements, including air interface enhancement, spectrum expansion, and network …

In this survey paper, we first provide insights on the evolution of radio access networks
(RANs) through investigating the existing paradigms and future trends towards 6G. We then …

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 …

The traditional multiple input multiple output (MIMO) systems cannot provide very high
Spectral Efficiency (SE), Energy Efficiency (EE), and link reliability, which are critical to …

We develop two distributed downlink resource allocation algorithms for user-centric, cell-
free, spatially-distributed, multiple-input multiple-output (MIMO) networks. In such networks …
