Researchers have developed an advanced in-context learning (ICL) framework to enhance pilot-based beamforming in multi-user multiple-input single-output (MU-MISO) systems. This framework integrates an ICL-Transformer backbone with pilot and beamformer encoder-decoder networks, enabling it to adapt to various channel models without retraining. Key innovations include a curriculum learning strategy for smoother convergence, a self-evolving mechanism for dynamic context dataset refinement, and a mismatch-aware extension that bypasses explicit channel calibrations. Simulation results demonstrate that this approach outperforms existing beamforming schemes, including Transformer-based methods and the WMMSE benchmark, by rapidly adapting to both known and unknown channel models.
