5G Radio Access Network (RAN) - Centralized RAN, Cloud-RAN and Virtualization of Small Cells

A book edited by Dr. Hrishikesh Venkataraman and Dr. Ramona Trestian


To be published by CRC Press, Taylor and Francis Group, USA



In the ever-evolving telecommunication industry, smart mobile computing devices have become increasingly affordable and powerful, leading to a significant growth in the number of advanced mobile users and their bandwidth demands. According to Cisco, high-end devices like smartphones, iPhones, netbooks, and laptops will account for 24.3 exabytes per month of data traffic by 2019. In order to achieve this, alternate solutions are required wherein traditional base stations can be replaced by a more generic, simple and small-sized nodes that can carry out minimal tasks such as RF operations; while moving other computationally intensive tasks such as resource allocation, baseband processing, etc. to a centralized location. In this context, C-RAN (Centralized or Cloud Radio Access Network), offers many advantages over traditional radio access network and the architecture design and techniques offered by C-RAN makes it a strong candidate to be incorporated into the 5G wireless network standard. C-RAN would enable joint scheduling and processing between multiple cells which would eventually enable a collaborative radio environment. Notably, C-RAN would enable a seamless integration between multiple operators and a multi-product vendor design. On similar lines, Small Cells have also been looked at, for moving the computation from the user terminal/ device to the network; either to Small Cell node itself or to the core network. In this regard, the functionality of Small Cells resemble to that offered by the C-RAN. In fact, with the rapid development of network function virtualization (NFV) in the telco world, communication service providers (CSPs) and product vendors have been looking to offer virtualized Small Cells.

Overall Objectives of This Book

Being at a very nascent stage, C-RAN and virtualized Small Cell technology poses several major research challenges. This book aims to provide a deeper insight into the next generation RAN architecture; especially in the presence of virtualization and cloud environment. The book will present a survey of the coexistence of SDN, C-RAN and Small Cells solutions proposed in the literature at different levels; e.g., physical characteristics, open access, dynamic resource allocation, technology-neutrality, coverage obligations, minimization of the interference problems, etc.

Potential Uses/Intended Audience

The prospective audience of this book is two-fold. On one side, it would be useful for undergraduate students, postgraduates and researchers who are interested in the emerging areas of software defined networks, Cloud-RAN, small cells, network virtualization etc. Moreover the book could be considered a link between the academia and industry wherein the industry could immensely benefit by applying the novel ideas or acknowledge issues in the real-world applications.

The editors invite potential authors to submit original contribution, ideas and research work as a chapter for this book. Recommended topics include, but not limited to:

·       Mobile network expansion solutions (Relay/Repeater, Carrier Wi-Fi, Distributed Antenna System, Small-Cell RAN, Cloud or Centralized-RAN etc.)

·       Emergence of a new RAN topology (from distributed RAN to C-RAN and virtualized RAN)

·       Architecture, design, implementation and evaluation of Virtualized-RAN systems

·       Analysis, modelling and characterization of Virtualized-RAN systems

·       Interference coordination, Dynamic resource allocation

·       Capacity and spectral efficiency improvement, Delay/Latency requirements in C-RAN

·       Small Cell backhaul and C-RAN fronthaul solutions
