Non-Orthogonal Multiple Access

Non-Orthogonal Multiple Access (NOMA) NOMA is a multiple access technique that has attracted a lot of interest from researchers and is considered a strong candidate for handling many of the requirements of 5G and beyond networks. Multiple access techniques allow multiple users to share the allotted resources in an effective manner. Recent studies categorize these techniques as Orthogonal Multiple Access (OMA) and Non-Orthogonal Multiple Access (NOMA). In OMA, each user can exploit […]

Minimizing Latency and Optimizing User Selection for 5G and Beyond Networks

Minimizing Latency and Optimizing User Selection for 5G and Beyond Networks The post below, is an oversimplification of the subject for the benefit of non-technical readers and the general public. Introduction The number of devices with mobile access, emerging with the development of the Internet of Things (IoT), is constantly increasing. At the beginning, the mobile phone was the only type of device that could access and utilise telecommunication networks. […]

New Waveforms for 5G and Beyond Networks

Introduction The telecommunication industry has experienced enormous growth over the last few decades. It all started when the first generation (1G) of mobile telecommunication standards, which were analog systems, were introduced in the early years of the 1980s. 2G telecommunication systems soon replaced 1G. Compared to 1G, 2G was digitally encrypted, more spectrally efficient and also enabled users to now exchange plain text-based messages with its Short Message Service (SMS). […]

Massive MIMO with 3D Beamforming in mmWave Band

Why mmWave? With the increasing heavy traffic due to HD video transmission, virtual reality, Internet of Things (IoTs), it can be predicted that existing 4G LTE will not be enough to meet the demands that networks will face in near future. Hence, 5G technology is just about to replace the existing 4G LTE and hit the market hopefully by 2020. 5G technology will offer a network which will be more […]

Novel Radio Access Network Technologies: The Physical Layer point of view

In today’s mobile networks, we are used to having high speed connectivity most of the times. Hence, a natural question is why do we need to invest so much effort and resources in developing new and more advanced techniques? The answer is that the value is shifting from providing high speed connectivity for mainly man-controlled devise, such as smartphones, to enabling the coexistence of a network of things such as […]

Improving quality of experience for video streaming

Video accounts for 56% of the current (2017) mobile network traffic and is expected to be responsible for 73% by 2023 [1]. Consequently, optimization concerning video delivery has been gaining more and more interested and is the subject discussed in this article. To adapt to the heterogeneity of networks and the variable available bandwidth, the state of the art in delivering video is the adaptive video streaming (ABR). The delivery […]

Splitting Network Functions in 5G

5G networks are expected to support various applications with a high flexibility meeting diversity of requirements in terms of latency, data rates and massive connectivity.   A 5G network function (NF) supply a particular capability to support communication through a 5G network. NFs are normally virtualized, but some functions may need addition of more specialized hardware. NFs can be the functions that are common functions which are essential for all […]
