11.1 Introduction

The 5^th generation (5G) air interface (AI) constitutes the complete radio access network (RAN) protocol stack, i.e., the physical layer (PHY), Media Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), Radio Resource Control (RRC) and Service Data Adaptation Protocol (SDAP), and all related functionalities describing the interaction between infrastructure and device. Furthermore, it covers all services, bands, cell types, etc., expected to characterize the overall 5G system. This chapter describes the lower part of the protocol stack, namely, PHY/MAC related technologies, and highly related aspects, such as antenna design. Before heading to the detailed elaborations in subsequent sections, we start with establishing basic design criteria and assumptions. While we keep this ...
