Claim 0:
1. A method of transmitting and receiving signals by a user equipment supportive of a Non-Terrestrial Network (NTN) in a wireless communication system, the method comprising:
receiving System Information Block (SIB) including NTN-specific parameters for a serving cell,
wherein the NTN-specific parameters for the serving cell includes (i) a parameter for a common Timing Advance (TA) value and (ii) a parameter for a drift rate of the common TA value;
determining a TA value related to a serving satellite for the serving cell based on the first common TA value, the drift rate, a specific time and a current time; and
transmitting a signal based on the TA value related to the serving satellite,
wherein the common TA value is a timing offset that is equal to a Round Trip Time (RTT) between the serving satellite and a reference point, where the reference point is located in a feeder link.
