. Chapter 7 provides insights into waveform parameter assignment considering the cur- rent waveform design in 5G new radio (NR). This chapter first reviews the literature on waveform parameter assignment in the context of multi-numerology RAN slicing. Then the waveform parameter options for the 5G NR are introduced. Finally, the chapter discusses numerology assignment, waveform processing, and the related joint optimization issues. Part II The authors in Chapter 8 highlight the advantages and the issues of network slicing when it is implemented in a dynamic spectrum-sharing manner. The authors start by discussing the motivations behind spectrum sharing in future networks. This is then followed by a histor- ical overview of the approaches to spectrum sharing. Then the concept of network slicing, different types of network slicing, and network slicing in RANs are introduced. Finally, the chapter defines the concept of isolation and presents results on isolation using connection admission control (CAC). Chapter 9 discusses access control and handoff policy design for RAN slicing where a uni- fied framework for access control is presented. Additionally, user access control policies to select admissible users for optimizing the quality of service (QoS) and the number of admis- sible users is designed. This is followed by the investigation of the handoff issue for mobile users in RAN slicing. Then a multi-agent reinforcement learning based smart handoff pol- icy is presented. This will reduce handoff cost while maintaining user QoS requirements in RAN slicing. Finally, the performance of the designed policy in reducing the handoff cost is numerically evaluated and compared with traditional policies without learning. Preface Chapter 10 presents a mechanism to address slice recovery and reconfiguration in the unified framework. This chapter first formulates a recovery problem to address the failures of substrate networks and the uncertainties of traffic demands in a RAN slice. Based on that, two robust RAN slicing algori
