摘　　要：通过分析5G网络关键技术特点及其对覆盖性能影响,提出了5G无线网络规划中基于3GPP Uma-NLOS传播模型的5G NR 3.5 GHz频段链路预算方法,针对Uma-NLOS模型给出了典型城区场景链路预算中关键参数的取值。进一步分析对比4G与5G NR的链路预算结果,并根据链路预算结果提出与4G共存下,5G初期的覆盖组网策略,为5G网络规划提供重要依据。By analyzing the key technical features of 5G network and its impact on coverage performance,a 5G NR 3.5 GHz downlink budget method based on 3GPP Uma-NLOS propagation model on 5G wireless network planning is proposed.For the Uma-NLOS model,the key parameters in the link budget of typical urban scenes are given.The link budget of 4G and 5G NR is further analyzed and compared.Based on the result of the link budget,a networking scheme is proposed in the earlier 5G era,which provides an important basis for 5G network planning.
