Title:
METHOD FOR REPORTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/145716
Kind Code:
A1
Abstract:
The present invention discloses a method for reporting channel state information (CSI) in a wireless communication system, and an apparatus therefor. Particularly, a method by which a user equipment (UE) reports channel state information (CSI) in a wireless communication system comprises the steps of: receiving, from a base station (BS), CSI-related configuration information; receiving, from the base station, a reference signal; calculating CSI on the basis of the reference signal; and transmitting the CSI to the base station, wherein the CSI includes information related to a codebook, the information related to the codebook includes a bitmap related to an amplitude coefficient and a phase coefficient, and the size of the bitmap may be set by multiplying the number of bases of a spatial domain for the CSI by the number of bases of a frequency domain for the CSI.
