Even if the 5G system will introduce a set of brand new functionalities, the evaluation framework does not need to be developed from scratch. There is a clear experience of success in the process followed
for the evaluation of International Mobile Telecommunications Advanced (IMT‐A). IMT‐A is recognized as the 4th generation (4G) of mobile and wireless networks, the one generally recognized as the enabler of the widespread success of mobile broadband applications. In the 2007‐2008 timeframe, the radio sector of the International Telecommunication Union (ITU‐R) Working Party (WP) 5D developed the evaluation guideline for IMT‐A for its performance assessment, and defined performance metrics and technical performance requirements. A summary of these can be found in two ITU‐R reports, i.e., the report on guidelines for the evaluation [1], and the report on radio interface requirements [2]. The former report contains the detailed simulation assumptions and the evaluation methodologies for IMT‐A. This document represents a significant reference ensuring the proper harmonization of the tools used by the independent external evaluation groups for the performance evaluation of IMT‐A technology candidates. It includes three components of the evaluation framework:
Test environments, which consist of:
A traffic model based on the service to be evaluated;
A deployment scenario, which provides the geographical characteristics where the service is
deployed (e.g., indoor hotspot, dense urban area);
An evaluation configuration, i.e., the assumed evaluation parameters applied to the selected
traffic (service) and deployment scenario.
Evaluation methodology and procedures for each key performance indicator (KPI):
High‐level assessment method, e.g., inspection, analysis or simulation
Detailed evaluation method and procedure.
Evaluation models, e.g., channel model.
