English(EN) Beamforming Design Via GNN in mmWave Cell-Free Massive MIMO Using Sub-6 GHz CSI

图神经网络利用Sub-6 GHz CSI优化毫米波波束成形

研究人员开发了一种新颖的毫米波(mmWave)无蜂窝大规模MIMO系统的波束成形方法,该方法利用图神经网络(GNN)从Sub-6 GHz信道状态信息(CSI)中学习波束成形器。这种方法显著降低了获取完整毫米波CSI的相关开销。该系统被建模为无线图,并且GNN经过训练,通过捕捉用户间干扰和基站间协作来优化下行链路总速率。仿真结果表明,这种Sub-6 GHz辅助的基于GNN的波束成形器性能具有竞争力,通常优于依赖完整毫米波CSI的传统方法。 AI

影响 这项研究通过减少对大量信道状态信息的需求,可能带来更高效的无线通信。
