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: This disclosure relates to a 6G communication system for achieving high data transmission rates and ultra-low latency beyond 4G and 5G communication systems. The disclosure provides a method performed by a terminal in a wireless communication system or an apparatus related thereto, the method including receiving first information about at least one resource pattern associated with resource allocation of an uplink reference signal (RS) from a base station, receiving second information indicating one resource pattern among the at least one resource pattern from the base station, identifying a physical uplink shared channel (PUSCH) resource based on the first information and the second information, and transmitting an uplink signal to a base station based on the identified PUSCH resource.
