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.
