==WIRELESS COMMUNICATION DEVICE AND METHOD EMPLOYING CHANNEL STATE INFORMATION COMPRESSION - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18459969 titled 'WIRELESS COMMUNICATION DEVICE AND METHOD EMPLOYING CHANNEL STATE INFORMATION COMPRESSION

==Simplified Explanation==

The operating method of a wireless communication device involves receiving a channel state information reference signal (CSI-RS) from a base station, generating channel information based on the CSI-RS, and reporting the channel information back to the base station. The method includes compressing channel characteristic information in a spatial domain, then further compressing it in a frequency domain using a Discrete Fourier transform (DFT) function, and generating the final channel information based on the compressed data.

==Original Abstract Submitted==

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.
