In this chapter, starting with the recent trend in terrestrial and satellite backhaul technologies, we provide possible use cases for HSTB networks and their potential benefits and challenges. Subsequently, we focus on the spectrum sharing aspects of wireless backhaul networks considering the following two categories of enabling techniques: (i) spectral awareness techniques and (ii) spectral exploitation techniques. The first category mainly comprises radio environment awareness techniques such as spectrum sensing and databases while the second category includes interference mitigation and resource allocation techniques. Furthermore, we present three case studies along with the numerical results considering the coexistence of satellite and terrestrial systems in the Ka-band. Finally, this chapter provides some interesting recommendations for future research directions.
