Claim 0:
1. A method of performing a timing advance adjustment between a user equipment (UE) and a non-terrestrial network (NTN), the method comprising:
receiving and decoding a medium access control (MAC) control element (CE) including closed loop information;
receiving and decoding system information including open loop information;
determining a timing advance value based on either the closed loop information or the open loop information; and
controlling timing of an uplink transmission signal, transmitted from the UE, based on the timing advance value,
wherein determining the timing advance value comprises:
configuring a priority timer,
assigning a priority to either a closed loop method or an open loop method, and
using either the closed loop method or the open loop method to determine the timing advance value based on the assigned priority and a state of the priority timer.
