A Survey of 5G Network: Architecture and Emerging Technologies

Abstract

In the near future, i.e., beyond 4G, some of the prime objectives or demands that need to be addressed are increased capacity, improved data rate, decreased latency, and better quality of service. To meet these demands, drastic improvements need to be made in cellular network architecture. This paper presents the results of a detailed survey on the fifth generation (5G) cellular network architecture and some of the key emerging technologies that are helpful in improving the architecture and meeting the demands of users. In this detailed survey, the prime focus is on the 5G cellular network architecture, massive multiple input multiple output technology, and device-to-device communication (D2D). Along with this, some of the emerging technologies that are addressed in this paper include interference management, spectrum sharing with cognitive radio, ultra-dense networks, multi-radio access technology association, full duplex radios, millimeter wave solutions for 5G cellular networks, and cloud technologies for 5G radio access networks and software defined networks. In this paper, a general probable 5G cellular network architecture is proposed, which shows that D2D, small cell access points, network cloud, and the Internet of Things can be a part of 5G cellular network architecture. A detailed survey is included regarding current research projects being conducted in different countries by research groups and institutions that are working on 5G technologies.

Garther 2017 Топ Технологии: Их Анализ И Применение

“…5G использует технологию множественного доступа с разделением луча (Beam Division Multiple Access -BDMA) для взаимо-действия базовой станции с мобильными устройствами. Беспроводная сотовая ар-хитектура 5G обеспечивает пропускную способность 10-50 Гбит/с в милиметровом диапазоне частот 30-300 ГГц для прило-жений UHD видео и создания виртуаль-ной реальности [4]. Инновационная тех-нология 5G характеризуется использова-нием: массива приемо-передающих ан-тенн Massive MIMO, сети Cognitive Radio, организацией непосредственной связи D2D для IoT, созданием сети радиодосту-па, как облачной услуги (radio access network as a service) и облака виртуальных сетевых функций (network function virtualization cloud -NFV).…”

Massive MIMO Wireless Networks: An Overview

“…BSs can relatively easily avert transmission into undesired directions to alleviate harmful interference which, leads to low latency as well. In addition, massive MIMO makes a proper use of beamforming techniques to reduce fading drops; this further boosts signal-to-noise-ratio (SNR), bit rate and reduces latency [3].…”

Energy-Efficient Use of Licensed and Unlicensed Bands in D2D-Assisted Cellular Network Systems

“…Among the novel paradigms introduced in recent years is that known as the device-to-device (D2D) communication technique; this approach is widely thought to hold significant potential, as it could allow for emerging 5th-generation (5G) cellular network systems to offer a superior transmission mode (with a corresponding wireless interface) for the devices that use them [9,10]. In the D2D mode, the transmitter sends data directly to the receiver without using the BS, and can therefore replace the cellular mode over short transmission distances.…”
