5G Massive MIMO寻优验证与应用

5G Massive MIMO的多天线阵列系统增加了垂直维的自由度,可灵活调整水平维和垂直维的波束形状,并引出了立体覆盖波束Pattern这一概念。现网普遍采用厂家默认的Pattern,仅在单站和簇优化过程中根据测试情况,进行Pattern的局部优化,明显滞后。为探索不同场景5G Masiive MIMO最优配置,指导一线快速掌握不同场景下的Pattern经验值,支撑5G精准规划与优化,基于规划平台输出建议,在不同场景下开展Pattern权值寻优验证,并输出不同场景下的推荐值。

5G Massive MIMO Pattern Verification and Application

The 5G Massive MIMO multi-antenna array system increases the vertical dimension,which can flexively adjust the horizontal and vertical dimension of the beam shape,and the concept of three-dimensional covering beam,called Pattern,is introduced.At present,the default Pattern of the manufacturer is generally adopted in the current network.Only in the process of single station and cluster optimization according to the test conditions,not only the local optimization of Pattern is carried out,but also the 5G network planning and optimization lags behind.In order to explore the optimal configuration of 5G Masiive MIMO in different scenes,guide the front-line to quickly master the empirical value of Pattern in different scenes,and support 5G network planning and optimization,this paper carries out optimization of Pattern in different scenes,and verifies and outputs the recommended value in different scenes.
