Abstract: Provided is a method for receiving a signal by a terminal in a wireless communication system, the method comprising: receiving first data from a first transmission terminal and determining a HARQ feedback transmission time for the first data; receiving second data from a second transmission terminal and determining a HARQ feedback transmission time for the second data, wherein the first transmission terminal is aligned with the reception terminal by a first beam and the second transmission terminal is aligned with the reception terminal by a second beam; and based on the HARQ feedback transmission time for the first data and the HARQ feedback transmission time for the second data being identical with each other, modifying the HARQ feedback transmission time for the first data and transmitting, to the first transmission terminal, a negotiation message for indicating the HARQ feedback transmission time modification.

Abstract: The present disclosure is for performing positioning by means of a beamformed signal in a wireless communication system. An operation method by a terminal in a wireless communication system can comprise the steps of: transmitting first messages requesting transmission of a positioning reference signal (PRS) by means of a plurality of transmission beams; receiving from a second terminal a second message indicating at least one transmission beam among the plurality of transmission beams; transmitting a third message, comprising scheduling information for transmission of the PRS, to the second terminal by means of the transmission beam; and receiving the PRS from the second terminal on the basis of the scheduling information.
