    Abstract: An operation method of a terminal may comprise: receiving information on a common delay time between the terminal and the base station and information on a PRACH occasion through a service link established between the terminal and the satellite; calculating a first adjustment value based on the common delay time; transmitting a PRACH preamble through the service link at a first timing earlier by the first adjustment value than the PRACH occasion; receiving a random access response (RAR); calculating a second adjustment value based on the common delay time; and transmitting an uplink signal through the service link at a second timing later by the second adjustment value than the response delay time.
