Abstract
An operation method of a terminal in a communication system may include: estimating a propagation delay between the terminal and a first satellite, the first satellite being connected to the terminal and a base station of the communication system; estimating a terminal-specific TA value based on the propagation delay; transmitting, to the base station, a terminal-specific TA report based on the terminal-specific TA value; and performing update of a first TA value for communication with the base station based on the terminal-specific TA value, wherein a time point at which the update of the first TA value is performed is determined based on a first response of the base station to the terminal-specific TA report.
