5Radio Network
5.1 Overview
This chapter presents the new 5G radio interface and the principles in the functioning of the 5G radio network. The introduction gives a description of some of the most relevant theories and technologies related to 5G. Then, an overview of the 5G spectrum is given, including discussion of the feasibility of wider bandwidth utilization in theory and practice, planned 5G radio frequency (RF) bandwidths and band allocations, as well as the latest news and expectations of the World Radio Conference (WRC) of the radio section of International Telecommunication Union (ITU‐R) as the forum establishes the foundation of the global utilization and rules of the 5G radio frequencies.
Next, the 5G Radio Access Technologies (RATs) are discussed with an explanation of the principles of established and further expected technologies, advanced multiple‐in, multiple‐out (MIMO), and carrier aggregation (CA). This section includes discussion of the ITU‐R RAT candidates, proposed 3GPP design, and how it addresses the ITU‐R Recommendations and use cases for 5G.
This chapter also includes introduction to 5G user devices, and new aspects of 5G terminals. Then, the HW of the radio network equipment is described including the most relevant references for further information. One of the rapidly evolving areas in 5G is the antenna system, so it is explained according to the latest knowledge on evolved adaptive antenna systems and other novelty antenna solutions that are feasible ...
