Multi rtt positioning procedure with timing advance for ntn system

An apparatus for wireless communication, the apparatus being a user equipment (UE), comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to:
• determine multiple uplink measurement occasions for transmitting multiple reference signals to a satellite in a non-terrestrial network (NTN);
• generate, based on Global Navigation Satellite System (GNSS) location data of the UE and ephemeris data of the satellite, multiple timing advance (TA) reports that are linked to the multiple uplink measurement occasions, respectively;
• transmit the multiple TA reports to the satellite at multiple time points;
• and
• transmit the multiple uplink reference signals to the satellite on the uplink measurement occasions.

A computer-readable medium storing computer executable code for wireless communication of a user equipment (UE), comprising code to:

• determine multiple uplink measurement occasions for transmitting multiple reference signals to a satellite in a non-terrestrial network (NTN);
• generate, based on Global Navigation Satellite System (GNSS) location data of the UE and ephemeris data of the satellite, multiple timing advance (TA) reports that are linked to the multiple uplink measurement occasions, respectively;
• transmit the multiple TA reports to the satellite at multiple time points;
• and
• transmit the multiple uplink reference signals to the satellite on the uplink measurement occasions.
