Abstract: The present disclosure provides a method for performing channel estimation using a demodulation reference signal (DMRS) in a wireless communication system. More specifically, the method, which is performed by a base station, comprises: when a collision between a DMRS symbol and a synchronization signal block (SSB) occurs, shifting a resource block (RB) of the DMRS symbol where the collision occurs, and all REs bundled with the RE of the DMRS symbol where the collision occurs; transmitting information on the shifted REs to a terminal; and transmitting the DMRS to the terminal on the shifted REs.
