This article explores the duality principle for joint precoding design in cell-free massive MIMO networks, focusing on optimal solutions under power and information constraints. It discusses the application of team MMSE precoders and the derivation of a novel uplink-downlink duality principle for fading channels. The study addresses the challenges of limited CSI sharing and power control, providing insights into optimal joint precoding structures.
