5G Explained

2Requirements

2.1 Overview

This chapter summarizes the technical requirements for fifth‐generation (5G) systems. It should be noted that this book assumes ITU (International Telecommunications Union) to be the highest authority dictating the minimum 5G requirements. This book thus walks the reader through the explanation of the latest ITU statements for their 5G candidate selection. Furthermore, this chapter summarizes the statements the other relevant standardization body has presented, the Third Generation Partnership Project (3GPP) being one of the most active stakeholders in the standardization of the 5G.

The time schedule for the key aspects of the 5G development and deployment, by the writing of this publication, includes the ITU‐R's (the radio section of ITU) high‐level requirements presented in the document [1], and its finalized version [2]. The concrete requirement set for the candidate evaluation have been presented by the end of 2017 as stated in [3].

The 3GPP, on the other hand, is one of the most relevant standardization bodies to present a candidate 5G technology for ITU's 5G selection process. The 3GPP has sent the first draft technical specifications as defined in the Release 15 for the preliminary ITU‐R review, and the final submission will be based on the frozen technical standard set by Release 16.

Other candidate technologies might also be presented to the ITU evaluation, according to the ITU time schedule, although as an example, the Institute of Electrical ...
