Title:
METHOD FOR PERFORMING CHANNEL ESTIMATION USING DMRS IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/070105
Kind Code:
A1
Abstract:
The present specification 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 the steps of: 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 RBs bundled with the RB of the DMRS symbol where the collision occurs; transmitting information on the shifted RBs to a terminal; and transmitting the DMRS to the terminal on the shifted RBs.
