Dynamic Spectrum Access Decisions

Chapter 6Dynamic Spectrum Management for Cellular 5G Systems

Part 1 of this book presented the foundations of creating a hybrid DSA design while relying on examples of heterogeneous hierarchical MANETs that demonstrate the most critical aspects of DSA design needs. Chapter 5 showed how to design DSA as a set of cloud services with metrics to measure spectrum use optimization objectively. This chapter covers the use of DSA¹ with 5G cellular networks. There are commonalities and differences between hybrid DSA design for military cognitive MANET systems and DSA design for commercial cellular systems. With military MANET systems, all nodes in the network may be peers and all nodes may be mobile; there can be fast moving nodes such as fighter jets and slow‐moving nodes such as tanks and much slower nodes such as dismounted soldiers. A deployment of heterogeneous networks can be provisioned spectrum blocks for use in a nonopportunistic way. Waveforms forming networks may switch to opportunistic spectrum use in some cases but for the majority of the cases, networks use provisioned spectrum dynamically. These networks may share the provisioned spectrum blocks for an entire deployment dynamically before attempting to resort to the use of unlicensed bands. The problem domains in 5G cellular systems and military MANET systems are different, but they share many of the basic DSA concepts such as relying on spatial and time based sensing, collecting a knowledge repository, fusing the knowledge ...
