Title:
METHODS AND DEVICES FOR TRANSMITTING OR RECEIVING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/169181
Kind Code:
A1
Abstract:
Disclosed are methods and devices for transmitting or receiving channel state information (CSI) in a wireless communication system. A method for transmitting CSI according to an embodiment of the present disclosure may comprise the steps of: receiving configuration information related to CSI from a base station; receiving a CSI-reference signal (CSI-RS) on multiple CSI-RS resources from the base station; and transmitting first CSI to the base station on the basis of the configuration information. The multiple CSI-RS resources corresponding to the configuration information may be configured as one or more channel measurement resources (CMRs) and one or more CMR pairs; the one or more CMRs may be configured to be used for deriving the CSI on the basis of a single CMR; the one or more CMR pairs may be configured to be used for deriving the CSI on the basis of a single CMR pair; and unless there is a particular configuration according to the configuration information, no CMR included in the one or more CMR pairs may be used for deriving the first CSI, on the basis that the first CSI corresponds to the CSI derived on the basis of the single CMR.
