Title:

METHOD FOR DETERMINING DMRS LOCATION ON PHYSICAL SHARED CHANNEL RESOURCES IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE FOR SAME

Document Type and Number:

WIPO Patent Application WO/2020/091580

Kind Code:

A1

Abstract:

The present specification provides a method for determining the location of a DMRS on physical shared channel resources for data transmission in a wireless communication system. More specifically, in the method, implemented by a terminal, format information on a slot for the transmission of first data and second data is received from a base station, the first data and the second data is transmitted, on the basis of the slot format information, using a first physical shared channel group comprising a plurality of first physical shared channels and a second physical shared channel group comprising a plurality of second physical shared channels, respectively, at which point a first DMRS and a second DMRS are mapped to the first physical shared channel group and the second physical shared channel group, respectively.
