Abstract: Methods and apparatuses for performing communication in a wireless communication system. A user equipment (UE) receives first satellite ephemeris information related to a first satellite and information related to a first validity duration corresponding to the first satellite from a base station; and restarts a first validity timer, based on second satellite ephemeris information related to the first satellite being received from the base station while the first validity timer having the first validity duration is running. The UE obtains a first TA for the first satellite based on the first satellite ephemeris information before the first validity timer restarts, expires, or stops after starting based on the first validity duration, and the UE obtains a second TA for the first satellite based on the second satellite ephemeris information before the first validity timer expires or stops after restarting based on a second validity duration.
