摘要
当前关于5G新空口的研究主要集中在中高频段,4G使用的低频段重耕对于5G规模连片组网意义重大,但对此研究较少。在讨论影响无线电传播能力因素的基础上,选取3GPPTR38.901中城区室外非视线传播模型,使用当前主流空口参数,进行多系统主要物理信道传播能力的仿真。通过对比4G和5GNR各频段相同物理信道的覆盖能力,得到2.6GHz频段下的5GNR主要信道覆盖能力可在现有4G基础上实现连片覆盖。
The current research on 5G new air interface is mainly concentrated in the middle and high frequency bands.The low frequency band re-cultivation used by 4G is of great significance for 5G-scale contiguous networking, but there are few studies.On the basis of discussing the factors affecting the radio transmission capability,the urban outdoor non-line-of-sight propagation model of 3GPP TR38.901 was selected,and the current mainstream air interface parameters were used to simulate the multi-system main physical channel propagation capability.By comparing the coverage capabilities of the same physical channels in the 4G and 5G NR bands,the 5G NR primary channel coverage capability in the 2.6 GHz band can achieve contiguous coverage on the existing 4G basis.
