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: The present disclosure provides a method for reporting channel state information (CSI) in a wireless communication system. Specifically, a method for reporting, by a user equipment (UE), channel state information (CSI) in a wireless communication system includes: receiving, from a base station, control information related to a configuration of a channel state information reference signal (CSI-RS) resource, wherein the control information includes CDM type information representing a type of code division multiplexing (CDM) applied to the CSI-RS resource; receiving, from the base station, an X-port CSI-RS on one or more component CSI-RS resource element (RE) patterns; and reporting, to the base station, the CSI based on the received X-port CSI-RS. Accordingly, the present disclosure can flexibly provide CSI-RS resource locations.
