5G重叠覆盖对网络性能影响的研究

Research of overlap effect on 5G network performance

5G多波束天线相比4G单波束天线覆盖能力强,会造成同等站址规模下5G重叠覆盖比4G严重。而5G服务小区和邻小区广播波束信号强度测量值计算方式的不同,会缩小两者数值上的差异,进一步表现为5G重叠覆盖严重。本文对5G重叠覆盖度指标的意义和定义进行了分析,在现阶段只能沿用4G重叠覆盖度指标定义,对其中门限值给出了修正建议,另外对5G高重叠覆盖场景优化进行了探讨。

5G multi-beam antenna has stronger coverage than 4G single beam antenna,which will result in 5G overlapping coverage more serious than 4G under the same site scale.However,the difference between the 5G service cell and the adjacent cell in the calculation method of the measured value of SS-RSRP will narrow the diff erence between the two values,which is further refl ected in the serious 5G overlapping coverage.This paper analyzes the meaning and defi nition of 5G overlap coverage index and gives suggestions for revising the threshold value,also discusses the optimization of 5G high overlap coverage scenarios.
