    Abstract: Disclosed in the present invention is a method for receiving, by a terminal, a positioning reference signal (PRS) in a wireless communication system. In particular, the method comprises the steps of: receiving information related to a PRS search window for receiving a first PRS; receiving a plurality of first PRSs from a plurality of base stations on the basis of the first PRS search window; determining at least one second PRS search window on the basis of the plurality of first PRSs and the first PRS search window; and receiving a plurality of second PRSs from at least some of the base stations on the basis of the at least one second PRS search window.

    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.

    Abstract: Disclosed according to the present invention is a method for reporting a reference signal timing difference (RSTD) value by a terminal, in a wireless communication system. Specifically, the method may comprise: transmitting a random access preamble related to a synchronization signal/physical broadcast channel block (SS/PBCH block) received from a particular cell among multiple cells; requesting a radio resource control (RRC) connection to the particular cell on the basis of a random access response (RAR) received from the particular cell, to make establishment of the RRC connection to the particular cell; receiving, from a location server, a cell group identifier for a cell group including the multiple cells and independent cell information for each of the multiple cells; detecting second PRS sequences transmitted from the respective multiple cells on the basis of a first PRS sequence related to the cell group identifier; and reporting, to the location server, at least one piece of reference signal timing difference (RSTD) information acquired on the basis of the second PRS sequences and the independent cell information.
