Title:
METHOD FOR PERFORMING CHANNEL ESTIMATION IN WIRELESS COMMUNICATION SYSTEM AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/032631
Kind Code:
A2
Abstract:
The present specification provides a method for estimating a channel by a terminal in a wireless communication system supporting machine-type communication (MTC). Particularly, the terminal receives, from a base station, configuration information for receiving a cell-specific reference signal (CRS) and a dedicated demodulation reference signal (DMRS), and receives the CRS on the basis of the configuration information. The terminal then receives the DMRS and control information by means of an MTC physical downlink control channel (MPDCCH), performs channel estimation for the MPDCCH on the basis of the DMRS and the CRS, and demodulates the control information on the basis of the channel estimation, wherein one precoder among a plurality of candidate precoders applied to the CRS is applied to the DMRS.
