What is A Dynamic Power Allocation Approach For Downlink Cell-Free Massive MIMO With Graph Neural Network about?

This paper presents a novel dynamic power allocation approach for downlink cell-free massive MIMO networks using a dynamically connected graph neural network (DCGNN). The proposed method optimizes downlink power allocation to maximize sum-spectral efficiency (SE) while addressing challenges such as IoT device mobility and interference. Numerical results demonstrate that the DCGNN outperforms existing state-of-the-art techniques in terms of power allocation efficiency.
