Abstract: The present disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). The present disclosure relates to signaling for sliding window superposition coding transmission. A method for a first terminal includes receiving, from a base station, first information included in decoding related information on a higher layer signaling, receiving from the base station control information including second information included in the decoding related information, identifying the second information by decoding of the control information, and decoding data transmitted to the second terminal based on the first information and the second information.
