IMT-2020 Key Performance Indicators: Evaluation and Extension Towards 5G New Radio Point-to-Multipoint

5G New Radio (5G NR) is the first technology standard to enable mobile communications in three different usage scenarios: enhanced Mobile Broadband (eMBB), Ultra-Reliable Low Latency Communications (URLLC) and massive Machine Type Communications (mMTC). As a result of its technical impact, ITU-R considers 5G NR as candidate technology for the International Mobile Telecommunications for 2020 (IMT-2020) evaluation process. To assess 5G NR performance, IMT-2020 defines multiple Key Performance Indicators (KPIs) related to specific requirements to enable Point-to-Point communications (PTP). IMT-2020 does not consider Point-to-Multipoint (PTM) communications due to the absence of multicast/broadcast capabilities in the current 5G NR standardized solution. Nevertheless, PTM communications are proved to be a key feature for 5G applications in a wide number of vertical sectors as Media & Entertainment, Public Warning or Internet of Things. This paper performs an analysis of different IMT-2020 KPIs for 5G NR PTP and extends the evaluation to a PTM perspective. The results contribute to enhance the role of PTM communications towards the IMT2020 landmark.
