Abstract: A first base station and a central entity for use in a radio access network implementing a dual/multiconnectivity scheme where the first base station is caused to split downlink data associated with a plurality of user devices between a first path through the first base station and a second path through the at least one second base station. The splitting comprises a plurality of reinforcement learning agents associated with the plurality of user devices. The reinforcement learning agents apply a current common neural network policy to select a path amongst the first and the second paths based on observed performance metrics of the first and second paths and to generate a reward associated with the selected path and send their experiences to the central entity. The central entity updates the common neural network policy based on the received experiences. The central unit can be implemented in a RIC.
