- W3106338506 abstract "With the dramatic increment of data traffic, energy efficiency has become a critical concern in the beyond 5G mobile system. In this paper, we study the max-min fairness-based energy efficient transmission strategy design for multicell massive multiple-input multiple-output (MIMO) downlink transmission, exploiting the statistical channel state information (CSI). We first derive the closed-form eigenvectors of the optimal downlink transmit covariance matrices, which reduces the original precoding design into a power allocation problem. Then, by exploiting the minorization-maximization procedure and Dinkelbach's transform, we propose an iterative energy-efficient power allocation algorithm with low complexity and guaranteed convergence. The performance gain of the proposed algorithm over other baselines is demonstrated in the numerical results." @default.
