摘要
Massive MIMO技术在垂直维度和水平维度均具备良好的波束赋形能力,有效提升了5G覆盖,降低了干扰,增加了覆盖优化的灵活性。本文提出了一种根据覆盖区域内用户话务分布自适应权值优化的方法,通过动态调整同步信号(SSB)天线波束赋形,实现Massive MIMO小区覆盖与业务分布的实时匹配。
Massive MIMO has good beam forming ability in both vertical and horizontal dimensions,effectively reduces interference,and increases the fl exibility of coverage optimization.Based on the customer and traffi c distribution,the paper concludes an implementation of an adaptive weight optimization method to achieve the optimal matching between the coverage and the capacity of the Massive MIMO cell.
