Title:
METHOD FOR TRANSMITTING/RECEIVING DATA IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE FOR SUPPORTING SAME
Document Type and Number:
WIPO Patent Application WO/2019/177421
Kind Code:
A1
Abstract:
A method for transmitting/receiving data in a wireless communication system and a device for supporting same are presented. Particularly, a method by which a terminal receives a physical downlink shared channel (PDSCH) in a wireless communication system comprises the steps of: receiving, from a base station, downlink control information (DCI) for scheduling the PDSCH in a nth transmission time unit; and determining whether the PDSCH is received on the basis of the DCI, wherein the DCI includes information for indicating whether a demodulation reference signal (DMRS) for the PDSCH exists in the nth transmission time unit.
