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.
