1. A method of transmitting a demodulation reference signal for physical uplink control channel (PUCCH) in a wireless communication system, the method performed by a terminal and comprising:
receiving, from a base station, configuration information related to a uplink transform precoding;
based on the uplink transform precoding being configured:
generating a sequence used for the demodulation reference signal for the PUCCH based on a low peak to average power ratio (PAPR) sequence; and
transmitting, to the base station, the demodulation reference signal for the PUCCH based on the sequence used for the demodulation reference signal for the PUCCH,
wherein based on a length of the low PAPR sequence being 6, the low PAPR sequence is generated based on a base sequence based on one of at least one length-6 sequence determined based on ejφ(i)π/8,
wherein the i is an index of elements of each of the at least one length-6 sequence and from 0 to 5, and
wherein a set of values of (φ(0), φ(1), φ(2), φ(3), φ(4), φ(5)) includes i) (−7, −5, −1, −7, −5, 5), ii) (−7, 1, −3, 1, 5, 1), iii) (−7, 1, −3, 3, 7, 5), and iv) (−7, 3, 1, 5, −1, 3).
