Abstract:
Disclosed herein is a method for transmitting a demodulation reference signal for an uplink control signal in a wireless communication system.
Specifically, the method performed by a terminal includes: 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 a base station, the demodulation reference signal based on the sequence used for the demodulation reference signal, in which the length-6 sequence has an 8-phase shift keying (PSK) symbol as each element of a sequence.
