Abstract: An electronic apparatus and a method in a wireless communication system are disclosed. The electronic apparatus comprises processing circuitry configured to train a beam adjustment model for adaptive beamforming with training data, so that the beam adjustment model outputs, for any movement path of a user equipment, beam information which enables a beam adjustment time interval meeting a performance requirement of the user equipment to be optimized. According to embodiments of the disclosure, the beam adjustment model is trained by taking the beam adjustment time interval as an optimization target, and adaptive beamforming is performed using the trained beam adjustment model, so that it is possible to significantly reduce system overhead and measurement and processing overhead for beam adjustment, while ensuring communication performance of the user equipment.
