With the method, we learn a mapping between uplink Sub-6GHz channel estimates and the best downlink beam in heterogeneous scenarios with non-IID characteristics. We also devise FEDLION, a FL implementation of the Lion optimization algorithm. Our approach reduces the signaling overhead and provides superior performance, up to 33.6 % higher accuracy than a single FL model and 6 % higher than a local model.
