报告摘要：Radio map technology offers a refined solution to reduce MIMO beamforming's dependency on channel state information (CSI). A deep learning-based approach was introduced, to generate radio maps directly from raw CSI data of MIMO systems, presenting two baseline schemes—one predictive and another based on throughput. An end-to-end architecture, tailored to MIMO beamforming vectors from location data, is proposed to employ deep neural networks through a task-oriented design and a customized loss function. Numerical results highlight the advantages of this approach, suggesting the potential to replace MIMO CSI with location data. A cell-free massive MIMO beamforming framework was proposed further, that requires only UE location reporting, employing deep learning to construct a comprehensive radio map. To mitigate the random phase gap issue in cell-free MIMO, space-time block coding (STBC) is integrated. Simulation outcomes demonstrate the superior performance of the radio map method over location-based beamforming (LBB) and channel knowledge map (CKM) approaches, with STBC-enabled carrier aggregation (CA) and multi-BS coordination significantly improving communication performance.
