This text addresses primarily the 5G Physical Layer and more specifically those key technologies that facilitate the functioning of the physical layer. The physical layer, as the name implies, embodies those functions related to the physical realization of transmission between a base station and end user equipment. Among the physical layer technologies covered here are digital modulation, channel coding, multi-carrier based multiple-access techniques, multiple antenna techniques including beamforming, and a number of others. Following the presentation of these technologies, a high-level description of 3GPP’s new 5G radio access system known as New Radio (NR) is given and it is demonstrated how the key technologies presented earlier facilitate the attainment of many of the goals of the NR standards, including very low latency and the transmission of very high-speed data. Because of this very high data rate capability, NR synergistically supports competitive, very high data rate, fixed wireless access (FWA). As there is little to date in textbook literature on 5G FWA, this text fills the vacuum by devoting the last chapter to a high-level overview and the technical physical layer aspects of this important and expanding wireless application.
