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 …

Since the first cellular networks were trialled in the 1970s, we have witnessed an incredible
wireless revolution. From 1G to 4G, the massive traffic growth has been managed by a …

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

5G will have to support a multitude of new applications with a wide variety of requirements,
including higher peak and user data rates, reduced latency, enhanced indoor coverage …

This paper considers a downlink cloud radio access network (C-RAN) in which all the base-
stations (BSs) are connected to a central computing cloud via digital backhaul links with …

Ubiquitous cell-free massive MIMO (multiple-input multiple-output) combines massive MIMO
technology and user-centric transmission in a distributed architecture. All the access points …

Mobile data traffic grew by 74% in 2015 and it is expected to grow eight-fold by 2020. Future
wireless networks will need to deploy massive number of small cells to cope with this …

Abstract The future wireless Fifth Generation (5G) communication network required a higher
bandwidth in order to achieve greater data rate. It will be largely characterized by small cell …

Cell-free Massive MIMO (multiple-input multiple-output) refers to a distributed Massive MIMO
system where all the access points (APs) cooperate to coherently serve all the user …

Coordinated multi-point (CoMP) is a key feature for mitigating inter-cell interference, improve
system throughput, and cell edge performance. However, CoMP implementation requires …
