Abstract (in Japanese) (See Japanese page) 
(in English) This study focuses on cooperative beamforming among base stations in wireless communication technology and proposes a new approach based on the free energy principle (FEP). Conventionally, the trade-off between accuracy of channel information to be acquired and overhead has been a challenge in beamforming; FEP solves this trade-off by considering the trade-off between the value from observation and the value from action to select the optimal action. This makes it possible to respond to dynamic situations where environmental fluctuations occur by integrating adaptive search, reasoning, and learning. Furthermore, by introducing a hierarchical coordination structure, information sharing among base stations and indirect state sharing among agents are achieved, which improves the efficiency and stability of beamforming. In addition, this study assumes simultaneous execution of communication and real-world sensing by utilizing ISAC (Integrator Sensoring And Communication), and integrates feedback from terminals and terminal location information for channel state estimation, thereby reducing the overhead of The proposed method is based on the assumption of simultaneous communication and real-world sensing by utilizing SINRing And Communication. Simulation results show that the proposed method is effective in improving SINR (Signal to Interference and Noise Ratio) and stabilizing beamforming.
