Method and device for performing channel measurement by using CSI-reference signal corresponding to received channel measurement target

摘要

The present invention relates to a wireless communication system, and more particularly, to a method and device for transmitting/receiving channel state information. A method of a terminal for transmitting channel state information (CSI) according to an embodiment of the present invention includes: Receiving setting information on a basic channel measurement target from a base station; receiving channel measurement target indication information from the base station; performing a channel measurement by using CSI-reference signal (CSI-RS) corresponding to the channel measurement target; and transmitting CSI to the base station.

1. A method for transmitting channel state information (CSI) at a user equipment, the method comprising:
receiving, by the user equipment, configuration information about first channel measurement objects from a base station; obtaining, by the user equipment, channel measurement object indication information indicating second channel measurement objects from the base station when the user equipment receives the second channel measurement objects; generating, by the user equipment, the CSI by performing channel measurement using CSI-reference signals (CSI-RSs) corresponding to the first channel measurement objects or the second channel measurement objects; and transmitting, by the user equipment, the CSI to the base station, wherein the generating the CSI by performing the channel measurement comprises:
when the user equipment does not receive the second channel measurement objects, generating the CSI by performing channel measurement using the CSI-RSs corresponding to the first channel measurement objects; andwhen the user equipment receives the second channel measurement objects, generating the CSI by performing channel measurement using the CSI-RSs corresponding to the first channel measurement objects or the second channel measurement objects, wherein the first channel measurement objects and the second channel measurement objects are a CSI-RS configuration set.
