    Abstract: The present disclosure provides a method for transmitting a demodulation reference signal. Specifically, the method performed by the terminal comprising: receiving, from a base station, a radio resource control (RRC) signaling including control information representing that transform precoding for an uplink is enabled; generating a low peak to average power ratio (PAPR) sequence based on a length-6 sequence; generating a sequence used for the demodulation reference signal based on the low PAPR sequence; and transmitting, to the base station, the demodulation reference signal based on the sequence used for the demodulation reference signal, wherein the length-6 sequence has an 8-Phase Shift Keying (PSK) symbol as each element of the sequence.

    Abstract: Disclosed is a method for a terminal to receive a reference signal in a wireless communication system. In particular, the method comprises: receiving information informing of a mode associated with a repetitive use of a beam for a channel state information-reference signal (CSI-RS); and receiving a synchronization signal/physical broadcast channel (SS/PBCH) block and the CSI-RS multiplexed on the basis of the mode, wherein the reception priority for the SS/PBCH block is higher than the reception priority for the CSI-RS.
