Provided are a method and apparatus for performing multicast communication in a communication system based on LTE or LTE-Advanced. The method of a UE includes receiving a Single Cell-Multicast Control CHannel (SC-MCCH) by monitoring a downlink channel based on a preset Downlink Control Information (DCI) format, determining a DCI format for receiving a Single Cell-Multicast Traffic CHannel (SC-MTCH) based on Coverage Enhanced Mode (CEMode) information included in the SC-MCCH, and receiving the SC-MTCH by monitoring the downlink channel based on the determined DCI format for receiving the SC-MTCH.
