Title:
APPARATUS AND METHOD FOR FEEDING BACK CHANNEL STATE INFORMATION AT VARIABLE RATES IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/071460
Kind Code:
A1
Abstract:
The objective of the present disclosure is to feed back channel state information (CSI) at variable rates in a wireless communication system, and an operating method for a user equipment (UE) comprises the steps of: receiving configuration information related to a CSI feedback; receiving reference signals on the basis of the configuration information; generating CSI feedback information on the basis of the reference signals; and transmitting the CSI feedback information, wherein the CSI feedback information can include the number of CSI values that corresponds to a feedback rate.
