Abstract: Various example embodiments relate to downlink power allocation in general massive MIMO systems. A method may comprise: constructing a graph representing a plurality of user equipments and a plurality of access points, wherein the graph comprises a plurality of nodes, wherein each node represents a communication link between one user equipment of the plurality of user equipments and one access point of the plurality of access points, and for at least one node of the graph, determining a power control parameter for the access point associated with said node using a graph neural network, and transmitting the determined power control to the access point associated with said node.
