Abstract: The present invention provides a method for receiving, by a terminal, a downlink phase tracking reference signal from a base station in a wireless communication system, and a device for supporting the same. According to an embodiment applicable to the present invention, a terminal may receive, from a base station, a phase tracking reference signal on the basis of the number of phase tracking reference signal ports, which is determined on the basis of different methods, according to whether transmission configuration indication (TCI) state-related information exists in received downlink control information. Further, the base station may transmit the phase tracking reference signal to the terminal accordingly.

Abstract: The present invention provides a method for transmitting or receiving a downlink signal between a terminal and a base station in a wireless communication system and an apparatus for supporting same. According to an embodiment applicable to the present invention, a terminal may assume, on the basis of received first downlink control information (DCI), whether a first physical downlink shared channel (PDSCH) scheduled by the first DCI is received while overlapping with another physical downlink shared channel in terms of time/frequency resources, and on the basis of the assumption, the terminal can receive the first PDSCH more reliably.

Abstract: A method for transmitting an SRS by a user equipment may comprise the steps of: transmitting, to a base station, user equipment capability information including information on a frequency bandwidth where SRS frequency hopping for the user equipment is possible; receiving, from the base station, first information on an SRS bandwidth configuration and second information on the start point of an SRS frequency for transmission of an SRS; and transmitting the SRS to the base station on the basis of the first information and the second information, wherein the frequency bandwidth where SRS frequency hopping for the user equipment is possible corresponds to a partial frequency bandwidth within a bandwidth part (BWP) configured for transmission of the SRS. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

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.
