In addition, we describe a method that enables us to perform robust, low-complexity, arbitrary channel-dependent precoding with such arrays as well as a communication protocol that limits the computational complexity associated with beam tracking and dynamic load computation in static or low-mobility scenarios, such as indoor wireless access or wireless terrestrial backhaul use cases. Finally, we study the application of various user- and symbol-level precoding schemes in coordinated multiple-input multiple-output setups equipped with LC-MAMP arrays and we evaluate their performance through numerical simulations using a realistic channel model. The simulation results show that LC-MAMPs outperform equivalent digital antenna arrays.},
