This paper introduces CaFTRA, a framework for 6G wireless systems that eliminates real-time channel state information (CSI) feedback in MIMO transmission by predicting CSI from user geolocation using a Transformer network. It also proposes a many-to-one matching algorithm for efficient multi-base station (BS) association and resource block (RB) allocation in fully-decoupled radio access networks (FD-RAN), demonstrating significant improvements in spectral efficiency and user fairness compared to 5G.
