Abstract: A method for indicating preemption in a communication system is disclosed. A method for operating a terminal comprises the steps of: receiving, from a base station, information indicating a first resource area, to which a preemption-capable resource belongs, for transmission of first data; receiving resource allocation information of second data from the base station; performing a monitoring operation for detecting a PI indicating a preempted resource for transmission of the first data in the first resource area, when the first resource area overlaps with a second resource area indicated by the resource allocation information; and performing decoding on the basis of the detected PI. Therefore, the performance of the communication system may be improved.
