High-speed rail 5G network coverage enhancement method and device, equipment and storage medium

The invention provides a high-speed rail 5G network coverage enhancement method, device and equipment and a storage medium. A high-speed rail carriage communication system model is constructed based on double-layer transparent dynamic metasurface TDM window glass, a base station outside a carriage and communication users in the carriage; acquiring channel information in the high-speed rail carriage communication system model, and calculating a signal to interference plus noise ratio based on the channel information; determining a communication rate target in the high-speed rail carriage communication system model, and constructing a non-convex optimization problem based on the communication rate target and the signal to interference plus noise ratio; the non-convex optimization problem is converted and solved, an association strategy among TDM window glass, a base station and communication users in a carriage is obtained, high-speed communication of millimeter wave signals of a high-speed rail system can be a
