A user equipment (UE) includes a transmitter that transmits, to a base station (BS), Demodulation Reference Signals (DM-RSs) using Discrete Fourier Transform (DFT)-spread (s)-Orthogonal Frequency-Division Multiplexing (OFDM). The resource elements (REs) that do not multiplex the DM-RSs in an OFDM symbol are set as Null. The transmission power for transmission of the DM-RSs is different from transmission power for transmission of normal DM-RSs. The normal DM-RS is a DM-RS using a Cyclic Prefix (CP)-OFDM. The UE further includes a processor that determines the transmission power for the DM-RSs based on a reciprocal of frequency multiplexing density of the DM-RSs. The transmission power for the DM-RSs is two times more than the normal DM-RSs when a configuration of the DM-RSs is a DM-RS configuration type 1. The transmission power for the DM-RSs is three times more than the normal DM-RSs when a configuration of the DM-RSs is a DM-RS configuration type 2.
