Abstract: A method for user association, i.e., user equipment-base station, UE-BS, association, in a cellular network is specifically designed for user association, for instance in 5G mmWave cellular networks. The method is based on the rational that network throughput may be low because of the weakest UE suffering from a weak direct link or high interference from other BSs in the network. Thus, swapping the worst UE-BS connection is likely to provide the UE a stronger link, i.e. a better connection to another BS, and/or reduce the interference, which consequently improves the throughput. An optional approach is based on matching theory, which uses preference lists maintained at the BSs and UEs.
