1. A method performed by a device for performing non-terrestrial network (NTN) based positioning, the method comprising:
receiving, by a user equipment (UE), a first reference signal (RS) from a base station (BS), wherein the first RS comprises a positioning reference signal (PRS) from the BS;
receiving a second RS from the BS, wherein the second RS is associated with the first RS and comprises one of: a second PRS, a tracking reference signal (TRS), a synchronization signal block (SSB), or a demodulation reference signal (DMRS) associated with the UE;
calculating a doppler measurement based on one or both of the first RS or the second RS; and
reporting the doppler measurement, wherein the doppler measurement is to be used for calculating a position of the UE.
