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.
