Abstract: An operating method of a wireless communication device includes receiving a reference signal from a base station, estimating a first channel between the wireless communication device and the base station based on the reference signal, extracting, based on a first artificial intelligence model trained to reduce a difference between the first channel estimated by the wireless communication device and a second channel estimated by the base station, a feature including grouped attributes from the first channel, quantizing the grouped attributes using a codebook that is based on a second artificial intelligence model and by generating one or more indices of the codebook for each group of the attributes, and transmitting, to the base station, a bitstream including combination information of the indices of the codebook.

Abstract: A wireless communication device is provided. The wireless communication device includes: a communication circuit configured to transceive a signal using a plurality of antennas; a processor configured to: detect a first interference for N resource blocks (RB) of the signal; based on the first interference being detected, perform a first whitening validation on the first interference; detect a second interference based on a result of the first whitening validation; and based on the second interference being detected, perform a second whitening validation on the second interference; and a whitening filter circuit configured to perform whitening filtering on results of the first whitening validation and the second whitening validation.
