Abstract: A method for a terminal reporting channel state information (CSI) in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: receiving, from a base station, channel state information-reference signal (CSI-RS) setting information for receiving a CSI-RS resource; receiving the CSI-RS resource on the basis of the CSI-RS resource setting information; and reporting CSI generated on the basis of the CSI-RS resource to the base station, wherein when the same CSI-RS resource is set for repeated transmission for the terminal, the CSI-RS resource setting information may include indicating information relating to the location of a subcarrier on which the same CSI-RS resource is mapped.

Abstract: A method for receiving control information for a reference signal related to phase noise estimation by a user equipment (UE) comprises receiving control information indicating whether the reference signal related to the phase noise estimation is transmitted; when the control information indicates that the reference signal is transmitted, receiving the reference signal based on the control information; wherein when a size of a traffic resource block (RB) for the UE is greater than a predetermined value, the control information indicates the reference signal is transmitted.

Abstract: Disclosed in the present specification is a method by which a terminal transmits and receives a synchronization signal in a wireless communication system, comprising the steps of: receiving, from a base station, a synchronization signal and an extended synchronization signal, which are repeatedly transmitted a predetermined number of times for each beam; acquiring time and frequency synchronization with the base station on the basis of the received synchronization signal and the received extended synchronization signal; and receiving a beam reference signal related to beam selection from the base station.
