Abstract: The present invention provides a method for transmitting a frame in a communication system that generates layer 2 (L2) signalling information related to an L2 service, that checks whether a baseband frame (BBF) exists that is divided from BBFs forming a frame and respectively included in the frame and other frames, that constitutes the frame such that a baseband packet (BBP) corresponding to the first BBF of the BBFs includes the L2 signalling information if there is no BBF included in the respective frame and the other frames, and that transmits the same.
