1. A method of operating a first terminal in a wireless communication system, the method comprising:
transmitting first messages requesting to transmit a positioning reference signal (PRS);
receiving a second message related to the PRS;
transmitting a third message including scheduling information for transmitting the PRS using at least one transmit beam, indicated by the second message, among the plurality of transmit beams;
receiving PRSs;
measuring timing of the received PRSs; and
performing an operation for positioning based on the timings,
wherein the first message is transmitted by using a plurality of transmit beams, and
wherein at least one PRS of the PRSs is transmitted at a second terminal based on the scheduling information in the third message.
