Title:
METHOD FOR TRANSMITTING DEMODULATION REFERENCE SIGNAL REGARDING UPLINK CONTROL SIGNAL IN WIRELESS COMMUNICATION SYSTEM, AND APPARATUS THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/167075
Kind Code:
A1
Abstract:
The present specification provides a method for transmitting a demodulation reference signal regarding an uplink control signal in a wireless communication system. In particular, the method performed by a terminal comprises the steps of: generating a low PAPR sequence on the basis of a length-6 sequence; generating a sequence used in a demodulation reference signal regarding uplink data on the basis of the low PAPR sequence; and transmitting, to a base station, the demodulation reference signal on the basis of the sequence used in the demodulation reference signal, wherein the length-6 sequence is characterized as comprising an 8-PSK symbol for each element of the sequence.
