Analysis
This paper addresses the challenge of providing wireless coverage in remote or dense areas using aerial platforms. It proposes a novel distributed beamforming framework for massive MIMO networks, leveraging a deep reinforcement learning approach. The key innovation is the use of an entropy-based multi-agent DRL model that doesn't require CSI sharing, reducing overhead and improving scalability. The paper's significance lies in its potential to enable robust and scalable wireless solutions for next-generation networks, particularly in dynamic and interference-rich environments.
