Abstract: The present invention relates to a 6G communication system for achieving high data transmission rates and ultra-low latency beyond 4G and 5G communication systems. 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.

Abstract: An electronic device includes a housing structure including a plurality of antennas; a hinge; a first housing connected to the hinge and including a first surface and a second surface opposite to the first surface; and a second housing connected to the hinge and including a third surface and a fourth surface opposite to the third surface, a sensor module; and a processor operatively connected to the sensor module. The processor detects an unfolding operation or a folding operation between the first housing and the second housing using the sensor module, generate folding information on the unfolding operation or the folding operation based on a folding angle formed between the first housing and the second housing, when the unfolding operation or the folding operation is detected, and control an output of at least one antenna based on the folding information.
