1. A method performed by a terminal in a communication system, the method comprising:
receiving, from a base station, configuration information for a preemption indication via higher layer signaling;
receiving, from the base station, downlink control information (DCI) including a preemption indicator on a physical downlink control channel (PDCCH), the DCI being scrambled by a radio network temporary identifier (RNTI) for the preemption indicator; and
identifying resources indicated by the preemption indicator,
wherein the preemption indicator indicates the resources where no transmission for the terminal exists.
