1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from a base station, system information block (SIB) including information associated with a timing advance (TA);
identifying a first TA based on the information associated with the TA;
determining a second TA based on a position of the UE and a position of a serving satellite to compensate for link delay;
determining a third TA for transmission from the UE based on the first TA and the second TA;
receiving, from the base station, information for TA reporting, the information including offset for the TA reporting; and
transmitting, to the base station, a TA report related to the third TA.
