Abstract
A method is provided of optimizing multi-cell association for a downlink multi-user, multiple-input, multiple-output (MU-MIMO) system that includes a plurality of base stations corresponding to C number of cells which serve K user terminals. Each user terminal connects with at least two cells. The method includes determining which cells for each user to connect with based on minimizing an objective function that is dependent on at least weight parameters for each kth user connected to each cth cell. Based on the determination, the user terminals are connected to their respective cells and the weight parameters are applied toward a beamforming configuration for the plurality of base stations. A device is also provided having processing circuitry configured to perform the method.
