论文摘要
5G新无线电（NR）版本15已于2018年6月指定。它引入了许多变化和物理图数据传输的潜在改进，尽管仅考虑了点对点（PTP）通信。为了使用物理数据渠道，例如物理下行链路共享通道（PDSCH），必须通过物理下行链路控制通道（PDCCH）成功地保证控制控制信息。考虑到这两个方面，在本文中，我们首先分析了NR PTP中的PDCCH加工链以及最先进的长期进化（LTE）点对点 - 点对点（PTM）解决方案，即进化的多媒体多媒体广播多播服务（EMBMS）。然后，通过链接级别的模拟，我们比较了两种技术的性能，观察到各种情况的位/块错误率（BER/BLER）。目的是确定NR PDCCH中物理层变化带来的性能差距，并提供有关NR PTM方案的控制频道配置的有见地的指南。
5G New Radio (NR) Release 15 has been specified in June 2018. It introduces numerous changes and potential improvements for physical layer data transmissions, although only point-to-point (PTP) communications are considered. In order to use physical data channels such as the Physical Downlink Shared Channel (PDSCH), it is essential to guarantee a successful transmission of control information via the Physical Downlink Control Channel (PDCCH). Taking into account these two aspects, in this paper, we first analyze the PDCCH processing chain in NR PTP as well as in the state-of-the-art Long Term Evolution (LTE) point-to-multipoint (PTM) solution, i.e., evolved Multimedia Broadcast Multicast Service (eMBMS). Then, via link level simulations, we compare the performance of the two technologies, observing the Bit/Block Error Rate (BER/BLER) for various scenarios. The objective is to identify the performance gap brought by physical layer changes in NR PDCCH as well as provide insightful guidelines on the control channel configuration towards NR PTM scenarios.
