3. Resource Management for Network Slicing

Radio resource management is categorized among the biggest challenges for the 5G networks due to the proliferation of heterogeneous devices. Moreover, the introduction of 5G verticals and the need to fulfill heterogeneous stringent requirements based on novel applications further complicates the radio resource management process. Network slicing can be considered as a promising scheme to meet these heterogeneous requirements produced by various 5G verticals. In network slicing, the physical resources (radio access network resources, i.e., subcarrier power, spectrum, infrastructure, etc.) are sliced into multiple logical networks based on the application requirements. In this chapter, first, we discuss about the radio access network resources. Then, we briefly elaborate on network slicing and its challenges for achieving efficient resource management. Moreover, we aim to expose the readers to the resource management approaches that can support us to build efficient network slices for 5G verticals. Finally, we provide a use case for vertical industries pertaining to the resource management in virtual reality.
