Abstract

The present specification relates to a method for estimating an inter-symbol phase rotation difference in a wireless communication system, the method performed by a terminal comprises the steps for: receiving, from a base station through a DMRS symbol, a plurality of demodulation reference signals (DMRS), each signal corresponding to each layer; receiving at least one first reference signal used for an estimation of the intersymbol phase rotation difference from the base station via a specific resource region; and estimating the intersymbol phase rotation difference on the basis of at least one of the plurality of DMRSs or the at least one first reference signal.
