5G Radio Access Networks: Enabling Efficient Point-to-Multipoint Transmissions

This article provided a performance comparison of 5G PTM and 5G unicast, which is the baseline for PTM enhancements. A key observation is that 5G unicast fully outperforms 5G PTM in the case of a lower number of UEs. In some cases, 5G unicast provides better average SE than 5G PTM, while the cell edge performance (fifth -percentile user SE) is lower than that of PTM for a medium number of UEs. However, for high penetration of UEs, 5G PTM fully outperforms 5G unicast.
