Mobility and Coverage Evaluation of New Radio PDCCH for PointtoMultipoint Scenario This paper provides the mobility and coverage evaluation of New Radio (NR) Physical Downlink Control Channel (PDCCH) for PointtoMultipoint (PTM) use cases, e.g., eMBMS (evolved Multimedia Broadcast Multicast Services). The evaluation methodology is based on analyses and link level simulations where the channel model includes AWGN, TDLA, TDLC as well as a modified 0dB echo to model different PTM scenarios. The final version of this work aims to provide insightful guidelines on the delayecho tolerance of the NR PDCCH in terms of mobility and coverage. In this paper, it is observed that under eMBMS scenario, i.e. SFN channel, due to the time domain granularity of pilots distributed inside the PDCCH region, the system can support very high user movement speedDoppler with an relatively low requirement on the transmit SignalCarriertoNoise Ratio (SNRCNR). On the other hand however, the system falls short on its coverage due to the low frequency domain granularity of pilots that effects the channel estimation accuracy.

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.
