摘要
Pre5G 3D MIMO站点以精准的空间波束成形和空分复用技术,能极大提升网络容量,但3D MIMO站点暂无基于用户感知的容量评价体系.为了解决3D MIMO容量标准问题,通过业务感知测试App,拟合出Web浏览类、FTP下载类、视频类以及即时通信类业务用户实际感知与业务表现间关联.分4种场景实测,获取不同业务感知受限时的用户极限以及同频站点信道利用率对3D MIMO小区业务感知的影响拐点.形成一系列3D MIMO站点扩容门限,有效支撑了3D MIMO站点的规划和维护.
With the help of Space Beamforming and Space Division Multiplexing,Pre5G 3D MIMO can significantly increase site capacity.But there is not a performance evaluation system based on quality of user’S experience.To solve out the issue of 3D MIMO capacity standard,a fitting method is presented in this paper,which Can correlate the network performance with the experience of certain activities,such as Web browsing,FTP,Video or hsmnt Messaging.Through this method,we can find difference inflexions of user number and channel utilization in four scenarios that user experience becomes poor under tIle 3D MIMO site.Then we Call work out a series of expanding thresholds tO support the site planning and maintenance of3D MIMO site.
