The present disclosure discloses a method and an apparatus for allocating a PTRS in a next-generation communication system. ## Claims ### Claim 1 A method performed by a terminal in a wireless communication system, the method comprising: identifying a plurality of resource elements (REs) for a phase tracking reference signal (PTRS); receiving, from a base station, the PTRS on at least one RE among the plurality of REs; and performing a phase tracking using the PTRS received on the at least one RE, wherein an RE on which another reference signal is received among the plurality of REs is not used for the receiving of the PTRS, and wherein the phase tracking is performed without the RE on which the other reference signal is received. ### Claim 2 (depends on 1) The method of claim 1, wherein a PTRS corresponding to the RE on which the other reference signal is received is punctured. ### Claim 3 (depends on 1) The method of claim 1, wherein a phase tracking of at least one adjacent RE is used for the phase tracking for the RE on which the other reference signal is received. ### Claim 4 (depends on 1) The method of claim 1, wherein the PTRS is allocated to at least one orthogonal frequency division multiplexing (OFDM) symbol that is contiguous on a time-axis. ### Claim 5 (depends on 1) The method of claim 1, wherein the other reference signal comprises a demodulation reference signal (DMRS) or a channel state information reference signal (CSI-RS). ### Claim 6 A terminal in a wireless communication system, the terminal comprising: a transceiver configured to transmit and receive a signal; and a controller coupled with the transceiver and configured to: identify a plurality of resource elements (REs) for a phase tracking reference signal (PTRS); receive, from a base station, the PTRS on at least one RE among the plurality of REs; and perform a phase tracking using the PTRS received on the at least one RE, wherein an RE on which another reference signal is received among the plurality of REs is not used for the receiving of the PTRS, and wherein the phase tracking is performed without the RE on which the other reference signal is received. ### Claim 7 (depends on 6) The terminal of claim 6, wherein a PTRS corresponding to the RE on which the other reference signal is received is punctured. ### Claim 8 (depends on 6) The terminal of claim 6, wherein a phase tracking of at least one adjacent RE is used for the phase tracking for the RE on which the other reference signal is received. ### Claim 9 (depends on 6) The terminal of claim 6, wherein the PTRS is allocated to at least one orthogonal frequency division multiplexing (OFDM) symbol that is contiguous on a time-axis. ### Claim 10 (depends on 6) The terminal of claim 6, wherein the other reference signal comprises a demodulation reference signal (DMRS) or a channel state information reference signal (CSI-RS). ### Claim 11 A method performed by a base station in a wireless communication system, the method comprising: identifying a plurality of resource elements (REs) for a phase tracking reference signal (PTRS);
