Abstract

The focus of this chapter is on dynamic spectrum sharing in hybrid satellite-terrestrial systems. We start by classifying the scenarios for those systems. The most important dynamic spectrum sharing techniques such as spectrum sensing, databases, beamforming, beam hopping, and adaptive frequency and power allocation are discussed and their applicability in different scenarios is analysed. Interference analysis shows how Ka band sharing between satellite and terrestrial systems can be enabled. Autonomous ships are defined as an interesting emerging application area for hybrid satellite-terrestrial systems. In order to make them operate reliably and safely both close to shoreline and in deep sea, multiple communication technologies are needed. Interference management and spectrum sharing techniques could be used e.g., to prevent blocking or hijacking of the control signalling of a ship. In addition, we discuss shortly the citizens broadband radio service (CBRS) concept in the 3.5 GHz band. Ideas to use CBRS and other database techniques in mmW bands to enable spectrum sharing between satellite and terrestrial components of a future 5G system are given.
