13. A method of wireless communication at a user equipment (UE), comprising:
receiving one or more timing advance (TA) commands from a non-terrestrial network (NTN);
adjusting, in response to a transmission timing difference between a transmission TA of the UE and a reference TA exceeding a threshold, a timing change having a total timing adjustment, other than a propagation delay adjustment based on an NTN node position update and a network-controlled common TA value, to satisfy one or more threshold requirements; and
transmitting an uplink transmission based on the adjusted timing change.
