WIPO Patent Application WO/2024/025294

A1

The present disclosure relates to a 5G or 6G communication system for supporting higher data transmission rates. Specifically, a method performed by a terminal in a wireless communication system comprises the steps of: receiving, from a base station, an RRC message including information indicating the number of ports; receiving, from the base station, a message for deactivating at least one port among ports corresponding in number to the number of ports, wherein the message includes resource allocation information in a frequency domain associated with the at least one port; receiving an CSI-RS from the base station via ports that are among the ports corresponding in number to the number of ports but exclude the at least one antenna port deactivated on the basis of the message; and reporting, to the base station, CSI acquired on the basis of the CSI-RS.
