The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present disclosure relates to a transmission method of a terminal comprising: determining a simultaneous transmission of first and second communication-based sidelink signals; determining a priority of the first and second communication-based sidelink signals in case that the simultaneous transmission is configured; and processing the first and second communication-based sidelink signals on the basis of the priority. ## Claims ### Claim at position 1 -15. (canceled) ### Claim 16 A method performed by a terminal in a wireless communication system, the method comprising: identifying a transmission of a first sidelink signal associated with a first radio access technology (RAT) and a transmission of a second sidelink signal associated with a second RAT; identifying whether the transmission of the first sidelink signal overlaps with the transmission of the second sidelink signal on a time domain; and transmitting one sidelink signal among the first sidelink signal or the second sidelink signal based on a first priority associated with the first sidelink signal and a second priority associated with the second sidelink signal, in case that the transmission of the first sidelink signal overlaps with the transmission of the second sidelink signal. ### Claim 17 (depends on 16) The method of claim 16, wherein the one sidelink signal with a highest priority based on the first priority and the second priority is determined. ### Claim 18 (depends on 16) The method of claim 16, wherein the first priority and the second priority are transferred from a higher layer of the terminal. ### Claim 19 (depends on 16) The method of claim 16, wherein the first priority is determined based on at least one of a proximity service (Prose) per-packet priority (PPPP) or Prose per-packet reliability (PPPR), and wherein the second priority is determined based on 5th generation quality of service identifier (5GQI). ### Claim 20 (depends on 16) The method of claim 16, wherein the first sidelink signal corresponds to a physical sidelink shared channel (PSSCH) using the first RAT, wherein the second sidelink signal corresponds to a PSSCH using the second RAT, wherein the first priority is obtained based on sidelink control information (SCI) scheduling a first physical sidelink shared channel (PSSCH), and wherein the second priority is obtained based on SCI scheduling a second PSSCH. ### Claim 21 (depends on 16) The method of claim 16, wherein the first sidelink signal corresponds to a physical sidelink shared channel (PSSCH) using the first RAT, and wherein the second sidelink signal corresponds to physical sidelink feedback channel (PSFCH) using the second RAT. ### Claim 22 (depends on 16) The method of claim 16, wherein the first priority corresponds to first quality of service (QoS) information associated with the first sidelink signal, and wherein the second priority corresponds to second QoS information associated with the second sidelink signal. ### Claim 23 (depends on 16) The method of claim 16, wherein the first RAT corresponds to a long-term evolution (LTE), and wherein the second RAT corresponds to a new radio (NR.). ### Claim 24 (depends on 16) The method of claim 16, wherein the time domain includes at least one symbol or at least one slot. ### Claim 25 A terminal in a wireless communication system, the terminal comprising: a transceiver;
