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.

Abstract: Disclosed herein are a method and a device for transmitting an uplink channel in a wireless communication system. According to the present disclosure, a UE transmits to a base station information associated with uplink transmission supported by the UE and the UE information includes a subset including at least one transmit precoding matrix indicator (TPMI) supported by the UE. The UE may receive from the base station uplink transmission information including a TPMI for transmitting an uplink channel and transmit to the base station the uplink channel based on the uplink transmission information, and the uplink channel may be transmitted through full transmission power configured by the base station based on a case where the TPMI is included in the subset.
