Abstract: Example embodiments of the present disclosure relate to channel state based beamforming enhancement. A first device receives, from a second device, a second message indicating a second channel state. The second message has a second length less than a first length of a first message indicating a first channel state previously received from the second device. The first device obtains combined beamforming features of the second device according to a trained combining model associated with the second device and based on the second message and historical beamforming features of the second device. The first device generates a beam weight for the second device according to a trained beamforming model and based on the combined beamforming features. The first device may generate a beam weight for the second device according to the beamforming model without recovering CSI from the message.
