5G建网初期SSB波束设置策略

SSB Beam Setting Strategy in the Initial Stage of 5G Network Construction

5G网络由于其自身特性及所分配频率,网络规划优化的重点是提升水平和垂直覆盖,SSB广播波束与赋形增益特性则是网络覆盖改善的技术关键点。通过研究5G NR网络SSB广播波束配置对于覆盖范围和接入性能的影响,结合仿真与测试结果分析了不同SSB广播信道波束配置的差异对比,最后针对立体覆盖场景,提出了采用水平多波束与垂直多层波束设计原则与建议,为5G网络在室外复杂场景下的覆盖规划与优化提供一定的参考。

Due to 5G network characteristics and its allocated frequency,network planning and optimization focuses on improving horizontal and vertical coverage,and SSB broadcast beam and its beamforming gain are the key point to improve network coverage.This paper studies the influence of the SSB beam configuration on the coverage and access performance in 5G NR networks.Combining simulation and test results,the paper analyzes the difference comparison of different beam configurations of SSB broadcast channel.Finally,the principles and suggestions are proposed to design horizontal and vertical multi-layer beam for three-dimensional coverage scenarios,which provides a certain direction for coverage planning and optimization methods of 5G network in outdoor complex scenarios.
