摘要
首先介绍了5GNR物理层的帧结构、物理信道和信号,重点分析了DM-RS结构;然后分析了TBS的计算过程;最后计算出了5GNR下行单用户(SU-MIMO)、下行单小区(MU-MIMO)、上行单用户(SU-MIMO)、上行单小区(MUMIMO)的理论峰值速率;并根据给定的时隙格式,计算出某5G试验网的下行单用户(SU-MIMO)、下行单小区(MU-MIMO)、上行单用户(SU-MIMO)、上行单小区(MU-MIMO)的峰值速率。
Firstly it introduces 5G NR physical layer including frame structure,physical channels and physical signals,the structure of DMRS is discussed in detail.Then it analyzes the calculation procedure of TBS. Finally,the theoretical peak rate of single user(SUMIMO) for downlink,single cel(l MU-MIMO)for downlink,single use(r SU-MIMO)for uplink,single cel(l MU-MIMO)for duplink are caculated. According to the given slot format,the peak rates in a 5G trial network of single user(SU-MIMO)for downlink, single cel(l MU-MIMO)for downlink,single user(SU-MIMO)for uplink,single cel(l MU-MIMO)for duplink are worked out.
