Abstract: Disclosed is a method and apparatus for transmitting information in a communication system. The present invention relates to a millimeter wave beamforming-based 5G or pre-5G wireless communication system for supporting a higher data rate beyond a 4G network or LTE system. A method according to the present invention comprises the steps of: determining the number of blocks and a window size for configuring a transmission period for sliding window superposition coding (SWSC); transmitting control information including the determined number of blocks and window size to a plurality of terminals participating in the SWSC; transmitting, in a first block within the transmission period, a signal in which a first message and a second message are superposition-coded by first and second codes; and when a message notifying that the first message is not successfully decoded is received, transmitting, in a second block, a signal in which the second message and the first message are superposition-coded by the first and second codes.
