Abstract: The present specification provides a method for measuring and reporting channel state information (CSI) in a wireless communication system and a device for same. More particularly, in a method for reporting channel state information in a wireless communication system, the method which is carried out by means of a base station can comprise the steps of: transmitting CSI report configuration information associated with a CSI report to a terminal, wherein the CSI report configuration information comprises information indicating a time offset for the CSI report; transmitting a channel state information reference signal (CSI-RS) to the terminal; transmitting control information, which is for triggering the CSI report, to the terminal; and receiving from the terminal the CSI report which is generated on the basis of the measurement with respect to the CSI-RS. Here, if the information indicating the time offset for the CSI report is configured in “0” value, the CSI-RS can be transmitted periodically or semi-continuously.

Abstract: Disclosed is a method for transmitting and receiving a channel state information (CSI)-reference signal (RS) in a wireless communication system.
Specifically, the method performed by a base station may include: configuring control information indicating that an antenna port for all CSI-RS resources included in a CSI-RS resource set is same, wherein the CSI-RS resource set is used for tracking at least one of a time or a frequency; transmitting the configured control information to a user equipment (UE); and transmitting the CSI-RS to the UE through all the CSI-RS resources.
In doing so, the UE is capable of performing time/frequency tracking more precisely.
