Beamforming and beam management in 5G and beyond

As the wireless communication world regarded fifth generation (5G) technology to overcome the rapid rise of wireless data traffic demand, millimeter-wave (mmWave) frequency bands have been considered as an outstanding solution to satisfy the requirement of 5G networks. In this chapter, beamforming structures in mmWave systems are extensively explained after a brief introduction of these techniques in earlier systems. This practical chapter helps one to examine the beam management concept that is introduced exclusively in mmWave frequencies, where the processes and performance for this concept are studied. New challenges and some future directions for beamforming and beam management have been debated at the end of this chapter.
