IMT2020 Key Performance Indicators: Evaluation and Extension Towards 5G New Radio PointtoMultipoint 5G New Radio (5G NR) is the first technology standard to enable mobile communications in three different usage scenarios: enhanced Mobile Broadband (eMBB), UltraReliable Low Latency Communications (URLLC) and massive Machine Type Communications (mMTC). As a result of its technical impact, ITUR considers 5G NR as candidate technology for the International Mobile Telecommunications for 2020 (IMT2020) evaluation process. To assess 5G NR performance, IMT2020 defines multiple Key Performance Indicators (KPIs) related to specific requirements to enable PointtoPoint communications (PTP). IMT2020 does not consider PointtoMultipoint (PTM) communications due to the absence of multicastbroadcast 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 u0026 Entertainment, Public Warning or Internet of Things. This paper performs an analysis of different IMT2020 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.

NOMA based 5G NR for PTM Communications Recent advances in broadband communications have led to the first standardization phase of 5G (Relxe2x80x99 15). Several works present this novel standard as the main solution in order to cover all the new requirements that have arisen in the multimedia delivery industry. However, the latest 5G release does not include the option of transmitting traditional broadcast services. That is why, in this paper, NonOrthogonal Multiple Access (NOMA) is presented as a promising candidate in order to boost the implementation of the broadcastmulticast communications within the 5G NR standard. Therefore, a 5G New Radio (NR) fully compliant simulation tool has been developed and NOMA multiplexing schemes have been added, introducing as few modifications as possible. The simulation platform and proposed techniques have been tested within two different use cases. Results present a better overall reliability performance of the communications by using NOMA. In fact, both services performance is improved when compared to traditional TDMA schemes, with a maximum gain around 4 dB.
