Abstract:
Disclosed herein is a method and apparatus for a User Equipment to perform a phase tracking in a wireless communication system. According to the present invention, it may be provided the method and apparatus including receiving, from a base station, a Demodulation Reference Signal (DMRS) configured according to a specific pattern through a DMRS symbol; receiving, from the base station, a plurality of reference signals used for the phase tracking, wherein the plurality of reference signals is transmitted on a specific antenna port, and received through a specific resource region identical to at least one different reference signal transmitted on a different antenna port for the phase tracking; and performing the phase tracking based on at least one of the DMRS or the plurality of reference signals.
