Title:
METHOD AND DEVICE FOR GENERATING REFERENCE SIGNAL SEQUENCE FOR PAPR REDUCTION IN MOBILE COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/050653
Kind Code:
A1
Abstract:
The present disclosure relates to a method for transmitting or receiving a signal by a terminal in a wireless communication system. A terminal according to an embodiment may: transmit terminal capability information relating to sequence initialization of a demodulation reference signal (DMRS) to a base station; receive DMRS configuration information determined on the basis of the terminal capability information from the base station; and receive the DMRS from the base station on the basis of the DMRS configuration information, wherein the DMRS is generated on the basis of a sequence initialization parameter determined on the basis of a code division multiplexing (CDM) group identifier included in the DMRS configuration information.
