Abstract

A cellular communication network can broadly be categorized into two parts, the core network and the radio access network (RAN). This chapter focuses on the latter part of cellular communication network, i.e. RAN. It briefly presents 5G specifications along with the enabling technologies that will support bringing the 5G networks to fruition. Then the chapter discusses different types of resources available for the RAN of future cellular systems that need to be managed for effective operations. It also discusses network slicing which can be considered as a promising scheme to meet the heterogeneous requirements produced by various 5G verticals. The chapter further provides a use-case that focuses on one of the most important requirements of virtual reality (VR), i.e. offloading computation task. Offloading intensive tasks to more resourceful devices such as clouds or mobile edge computing servers increases the computational capacity of VR devices.
