¿µ¹® ³»¿ë¿ä¾à This technical report presents a novel application of artificial intelligence (AI) for wireless network optimization, focusing on the training and inference of a decentralized AI model for distributed beamforming optimization. In a wireless network environment where all base stations (BSs) share radio resources and are interconnected via backhaul cooperation links, enabling the exchange of coordination messages, each BS determines its beamforming strategy based on its own local channel information and the received cooperative messages to maximize overall network performance. The proposed method supports large-scale BS deployments through a decentralized training process, making it suitable for next-generation wireless networks that demand high efficiency and low computational complexity.
