12 Claims

1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:

obtaining a first reference time related to transmission of a first reference signal (RS) for positioning;

determining a compensation value based on a difference between an uplink transmission timing, obtained from a timing advance (TA) and a downlink reception timing, and the first reference time; and

transmitting the first RS based on the compensation value,

wherein the first reference time is updated to a third reference time based on the difference between the uplink transmission timing and the first reference time being equal to or greater than a preset value,

wherein the compensation value is determined based on the third reference time, and

wherein a difference between the uplink transmission timing and the third reference time is less than the preset value.
