    Abstract: An electronic device may include: a display; at least one processor operatively connected with the display; and a memory configured to store a plurality of contents and operatively connected with the at least one processor, and the memory may store instructions that, when being executed, cause the at least one processor to: acquire a plurality of contents related to a first category from the memory; classify the plurality of contents into one or more groups, based on context information of the plurality of contents; identify at least one first content corresponding to a designated type from the one or more groups; generate a highlight content by using the at least one first content; generate a teed including the highlighted content and the plurality of contents, based on the one or more groups; and arrange the highlight content on an upper end of the feed to output on the display.

    Abstract: Provided is an operating method of a wireless communication device, the method including receiving a channel state information reference signal (CSI-RS) from a base station, generating channel information by estimating a channel between the wireless communication device and the base station, based on the CSI-RS, and reporting the channel information to the base station, wherein the generating of the channel information includes generating first compressed data by compressing, in a spatial domain, channel characteristic information of a subband in which the CSI-RS is received, generating second compressed data by compressing the first compressed data in a frequency domain by using a first Discrete Fourier transform (DFT) function having a size corresponding to the number of subbands in which the CSI-RS is received in a bandwidth part (BWP) for communication with the base station, and generating the channel information, based on the second compressed data.

    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.
