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.

Abstract: A method for receiving, by a base station, channel state information (CSI) in a wireless communication system. The method includes receiving, from a user equipment (UE), UE capability information related to at least one of channel state information-reference signal (CSI-RS) resources or CSI-RS ports; transmitting, to the UE, CSI-RS configuration information that includes information based on the UE capability information; transmitting, to the UE, a CSI-RS using at least one CSI-RS port based on the CSI-RS configuration information; and receiving, from the UE, the CSI, wherein the CSI is based on a measurement, for the CSI-RS, performed by the UE. Further, the UE capability information includes information for i) a maximum number of the CSI-RS resources and ii) a maximum number of the CSI-RS ports related to number of the CSI-RS resources configured based on the maximum number of the CSI-RS resources.

According to the present disclosure, a UE may transmit to a base station capability information associated with transmission power of the UE and the information may include a subset including at least one transmit precoding matrix indicator (TPMI) supported by the UE. The UE may receive first control information for transmitting a message associated with an initial access and the control information may include a TPMI used for the UE to transmit the message. Thereafter, the UE may transmit to the base station the message by using transmission power determined based on the TPMI and the transmission power may be determined according to whether the TPMI is included in the at least one TPMI.
