Abstract: Provided is a 5G or 6G communication system for supporting higher data rates than a 4G communication system. A method of a terminal in an NTN includes receiving a first broadcast message comprising at least part of synchronization information from a satellite at a first time point, receiving a second broadcast message comprising a remainder of the synchronization information from the satellite at a second time point, receiving a third broadcast message comprising location information related to a location of the satellite from the satellite at a third time point, determining a first location of the satellite at the first time point, a second location of the satellite at the second time point, and a third location of the satellite at the third time point, based on the first broadcast message, the second broadcast message, and the third broadcast message, determining a TA value related to a distance between the terminal and the satellite, based on the first location, the second location, and the third location, adjusting a transmission time point of an initial message for initial access to the satellite, based on the determined TA value, and transmitting the initial message to the satellite at the adjusted transmission time point.

Abstract: The present disclosure relates to a 6G communication system for accomplishing ultra-low latency and a data transmission rate higher than that of 4G and 5G communication systems. According to various embodiments of the present disclosure, even if a satellite forming a specific cell is changed in a non-terrestrial network (NTN), the terminal may change a satellite connection without initiating a procedure for synchronization with the changed satellite connection by performing uplink synchronization and downlink synchronization with the changed satellite on the basis of information for uplink synchronization and information for downlink synchronization that have been obtained in advance. Accordingly, even if a satellite in communication is changed, a users terminal can experience high communication quality without interruption, and there is no need to perform the synchronization procedure which is performed when the existing satellite is changed, such that the number of communication signals among the terminal, the satellite, a core network, and a server (e.g. an NTN management server), etc., can be reduced, thereby reducing management complexity in the server and reducing power consumption of the terminal.
