Title:
METHOD FOR TRANSMITTING/RECEIVING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/031856
Kind Code:
A1
Abstract:
The present invention relates to a method and a device for transmitting/receiving a reference signal by means of a terminal in a wireless communication system. According to the present invention, a method and a device may be provided whereby a terminal receives downlink control information from a base station, and on the basis of the downlink control information, receives a demodulation reference signal (DMRS) and downlink data via a plurality of antenna ports. The terminal demodulates the downlink data on the basis of the DMRS, wherein the downlink data is received in the same symbol as, or in a different symbol from the DMRS according to the number of symbols associated with the downlink data.
