Abstract: An operation method of a terminal in a communication system may comprise: receiving, from a satellite, transmission timing information including information on a first transmission timing of a first SSB of each of at least one local cell and information on second transmission timings of second SSBs of sub-cells belonging to each of the at least one local cell; identifying the first transmission timing of the first SSB and the second transmission timings of the second SSBs based on the transmission timing information; attempting to receive the second SSBs when the first SSB is received at the first transmission timing; acquiring cell access information from the second SSBs by receiving the second SSBs; and accessing the satellite by using the acquired cell access information.
