    Abstract: Disclosed are a method and apparatus for transmitting and receiving channel state information in a wireless communication system. The method for transmitting channel state information (CSI) according to an embodiment of the present disclosure, may comprise the steps of: receiving, from a base station, configuration information related to the CSI, wherein the configuration information includes information about a CSI-RS resource set; receiving a CSI-reference signal (CSI-RS) from the base station; and transmitting the CSI, to the base station, on the basis of the configuration information and the CSI-RS. The CSI-RS resource set may include M CSI-RS resource groups (M is a natural number), and the CSI may include N first CSI sets generated on the basis of a single CSI-RS resource in N mutually different CSI-RS resource groups (N≤M, N is a natural number) from among the M CSI-RS resource groups.

    Abstract: The present disclosure provides a method for transmitting a demodulation reference signal. Specifically, the method performed by the terminal comprising: receiving, from a base station, a radio resource control (RRC) signaling including control information representing that transform precoding for an uplink is enabled; 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 the base station, the demodulation reference signal based on the sequence used for the demodulation reference signal, wherein the length-6 sequence has an 8-Phase Shift Keying (PSK) symbol as each element of the sequence.
