Title:
METHOD AND DEVICE FOR TRANSMITTING OR RECEIVING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/240042
Kind Code:
A1
Abstract:
Disclosed are a method and a device for transmitting or receiving channel state information in a wireless communication system. A method for transmitting channel state information (CSI) according to an embodiment of the present disclosure may comprise the steps of: receiving, from a base station, first configuration information related to a CSI report and second configuration information related to a CSI resource, wherein the second configuration information includes information on M (M is a natural number) CSI resource sets associated with the first configuration information on the basis of a group-based report being configured by the first configuration information; receiving, from the base station, a CSI-reference signal (CSI-RS) on a plurality of CSI resources of the M CSI resource sets on the basis of the second configuration information; and transmitting the CSI to the base station on the basis of the first configuration information.
