The introduction of Multiple-Input Multiple-Output (MIMO) systems has dramatically transformed wireless communication systems, in particular in the Fifth Generation (5G) New Radio (NR) systems, fundamentally changing how signals are transmitted and received. MIMO technology deploys numerous antennas to transmit and receive multiple data streams simultaneously. The presence of obstructions and scatterers in wireless environments, varying in location, size, and shape, contributes to a high-dimensional feature space. As user devices move, the interaction of electromagnetic radio waves with surrounding objects and devices generates distinct patterns, called spatial fingerprints. By analyzing the behavior of the radio channel in real time through these spatial fingerprints and their temporal evolution, MIMO systems unlock significant opportunities for deeper insight into channel dynamics. These insights lay the groundwork for previously unforeseen functionalities in the Radio Access Network (RAN) domain of cellular networks, moving beyond the constraints of traditional approaches based on mathematical models and solutions.
