Latency-Aware Residual DRL for Energy-Efficient Multi-RIS Assisted High-Speed Railway Communications
Maximizing energy efficiency in multiple Reconfigurable Intelligent Surface (RIS)-assisted High-Speed Railway (HSR) networks presents a formidable challenge due to the coupled dynamics of high-mobility Doppler effects, strict latency constraints, and the necessity for joint transmit power and beamforming control.
