Abstract

The present specification discloses a method for estimating a phase rotation of a transmission port by a terminal in a wireless communication system, the method comprising the steps of: receiving one or more demodulation reference signals (DMRSs) from a base station in a DMRS symbol; receiving at least one first reference signal, used to estimate a phase rotation of a DMRS port, from the base station in a particular resource region; and estimating the phase rotation of the DMRS port on the basis of the at least one first reference signal.
