Title:
METHOD FOR REPORTING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE FOR SAME
Document Type and Number:
WIPO Patent Application WO/2021/029695
Kind Code:
A1
Abstract:
Disclosed are a method for reporting channel state information in a wireless communication system, and a device for same. Specifically, a method for a user equipment (UE) to report channel state information (CSI) in a wireless communication system includes the steps of: receiving BWP setting information related to a bandwidth part (BWP); receiving information activating a specific bandwidth part among at one or more bandwidth parts based on the BWP setting information; receiving a reference signal; calculating the CSI on the basis of the reference signal; and omitting a portion of the CSI from the activated specific bandwidth part on the basis of a priority rule, and transmitting the remaining portion, wherein the CSI may include information related to coefficients, each of elements of the information related to coefficients may be sorted into a first group or a second group on the basis of priority values, the priority values may be determined in such an order that higher indexes and lower indexes among indexes in a frequency domain associated with the elements sequentially cross over on the basis of a predefined specific index, and the priority of the first group may be defined in the priority rule as being higher than that of the second group.
