摘要
5G增强移动宽带(enhanced mobile broadband,eMBB)场景对于频谱效率、系统容量提出了较高要求。传统技术无法带来相应的性能提升,拟引入大规模天线、毫米波通信等技术,结合应用异构网络,提高系统性能。同时,目前针对e MBB场景关键技术的仿真评估较少,无法从仿真的角度说明各项技术的性能优势。通过搭建系统级仿真平台,评估了不同天线数目下大规模天线的性能,并根据异构网络下的仿真结果,总结了工作在毫米波频段的微基站密度与接入偏移对系统性能的影响,对5G网络的参数配置和网络建设都具有很大的参考价值。
The 5 G eMBB scenario puts high requirements on performance such as spectrum efficiency and system capacity.It was proposed to introduce technologies such as massive MIMO and millimeter-wave communication,and combine heterogeneous networks to improve system performance,because traditional technologies cannot bring about corresponding performance improvement.At the same time,there are few simulation evaluation results for the key technologies of the eMBB scenario,and the performance advantages of each technology cannot be explained from the perspective of simulation.The performance of massive MIMO with different antenna numbers by building a system-level simulation platform were evaluated,and the impact of the density and bias of micro BS in the mmWave frequency to the performance based on the results in the heterogeneous networks was summarized.It has great reference value for parameter configuration and network construction of 5G network.
