论文摘要
最近完成了第一个5G（第五代无线系统）新的无线电版本15。但是，该规范仅考虑使用Unicast Technologies，并且尚未考虑到点对点（PTM）方案的扩展。为此，我们首先在这项工作中介绍了最先进的LTE（长期进化）PTM技术的技术概述，即EMBMS（进化的多媒体广播多播服务），并通过链接级模拟调查物理层的性能。然后，基于仿真分析，我们讨论了两个当前EMBMS解决方案的潜在改进，即MBSFN（单个频率网络上的MBMS）和SC-PTM（单细胞PTM）。这项工作明确地着重于将当前的Embms解决方案提供5G候选技术，例如多个天线和毫米波，及其潜力满足下一代PTM传输的要求。
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.
