AIMM (AI-enabled Massive MIMO) is a CELTIC-NEXT European collaborative research and development project. The AIMM consortium targets radical performance improvements and efficiency dividends for 5G and beyond Radio Access Network (RAN), through advanced antenna array (Massive MIMO) and Reconfigurable Intelligent Surface (RIS) technologies, powered through and managed by the latest advancements in Artificial Intelligence (AI) and Machine Learning (ML).

The AIMM work-packages are broadly defined by the area of the end-to-end RAN delivery chain which they consider. This is illustrated in the figure below, which shows a simplified schematic diagram of RAN functions from higher protocol layer resource management at the left, through precoding and advanced antenna structures, across the radio interface to the services deployed by the end user. The areas of application of the different work-packages are illustrated below.
