摘要
5G采用大规模阵列天线设计,结合波束赋形技术,在不同的无线覆盖环境中,可以通过配置不同的广播波束权值,生成不同组合的赋型波束,具有不同的倾角、方位角、水平波宽和垂直波宽,能够满足不同无线环境的覆盖要求,为网络覆盖优化提供了新的思路和手段。本文基于现阶段5G网络技术水平,对广播波束权值方案制定进行了浅析,以MDT数据为核心,制定波束权值匹配方案,以此指导5G网络建设初期的覆盖优化和用户驻留优化工作。
5G uses a large-scale array antenna design and beamforming technologies.In different wireless coverage environments,different broadcast beam weights can be confi gured to generate different combinations of beamforming beams with different tilts,azimuths,horizontal beamwidths and vertical beamwidths.It can meet the coverage requirements of different radio environments and provide new ideas and methods for network coverage optimization.Based on the technical level of 5G networks,this paper analyzes the formulation of broadcast beam weight schemes.Based on MDT data,we formulate a beam weight matching scheme to guide coverage optimization and user camping optimization in the initial stage of 5G network construction.
