The first 5G (5th generation wireless systems) New Radio Release-15 was recently completed. However, the specification only considers the use of unicast technologies and the extension to point-to-multipoint (PTM) scenarios is not yet considered. To this end, we first present in this work a technical overview of the state-of-the-art LTE (Long Term Evolution) PTM technology, i.e., eMBMS (evolved Multimedia Broadcast Multicast Services), and investigate the physical layer performance via link-level simulations. Then based on the simulation analysis, we discuss potential improvements for the two current eMBMS solutions, i.e., MBSFN (MBMS over Single Frequency Networks) and SC-PTM (Single-Cell PTM). This work explicitly focus on equipping the current eMBMS solutions with 5G candidate techniques, e.g., multiple antennas and millimeter wave, and its potentials to meet the requirements of next generation PTM transmissions.

LTE eMBMS 开创性研究：迈向 5G 点对多点传输

第一个 5G（第 5 代无线系统）New Radio Release-15 最近完成。但是，该规范仅考虑使用单播技术，尚未考虑对点对多点 (PTM) 场景的扩展。为此，我们首先在这项工作中概述了最先进的 LTE（长期演进）PTM 技术，即 eMBMS（演进的多媒体广播多播服务），并通过链路研究物理层性能级模拟。然后基于仿真分析，我们讨论了当前两种 eMBMS 解决方案的潜在改进，即 MBSFN（MBMS over Single Frequency Networks）和 SC-PTM（Single-Cell PTM）。这项工作明确侧重于为当前的 eMBMS 解决方案配备 5G 候选技术，例如多天线和毫米波，
