According to one embodiment of the present invention, provided are a method and device wherein, in order to improve the coverage of a transmission end and the reception performance of a reception end, an AI model is trained on the PA input/output relationship at the reception end, and the trained AI model is used to compensate for PA nonlinearity in received data. In addition, according to one embodiment of the present invention, provided are a method and device wherein training of the AI model on the reception end is only instructed when training of the AI model is necessary, and a reference signal suitable for the training of the AI model is instructed. Accordingly, it is possible to reduce the signaling overhead, computational overhead, or power consumption generated during the training of the AI model. In addition, the reference signal having the same or similar characteristics as the data compensating for PA nonlinearity is used in the training of the AI model, and thus overfitting of the AI model can be prevented. Therefore, the AI model having optimal PA nonlinearity compensation performance can be obtained.
