What is Optimize Sum-Rate in Massive MIMO Systems about?

This paper investigates the downlink of a massive MIMO system, focusing on maximizing the sum-rate while considering circuit power consumption. It introduces a model that determines the optimal number of activated RF chains and proposes a greedy algorithm for antenna selection to balance power consumption and transmitted power. The findings highlight that the maximum sum-rate is not achieved by activating all RF chains, necessitating a strategic approach to resource allocation.
