Claim:
1. An apparatus for transmitting data in a communication system, comprising: a transmitting unit that transmits a first data packet to a receiver in the communication system; a receiving unit that receives reception information of the first packet from the receiver; a frame generation unit that checks the reception information received by the receiving unit to generate a plurality of frames containing data to transmit to the receiver, wherein the plurality of frames include a main frame including a plurality of main sequence frames corresponding to the data, and a redundancy frame of the main frame including a plurality of redundancy sequence frames corresponding to the plurality of main sequence frames; a packet generation unit that generates a second data packet to include a payload that includes the plurality of frames generated by the frame generation unit; and the transmitting unit that transmits the second data packet generated by the packet generation unit to the receiver, wherein the payload comprises the plurality of frames and a mode field, wherein the mode field contains information on the plurality of frames, wherein each main sequence frame of the plurality of main sequence frames corresponds with each redundancy sequence frame of the plurality of redundancy sequence frames, respectively, wherein the frame generation unit checks a loss ratio of the first data ticket through the reception information to generate the main frame, the redundancy frame of the main frame, and an XOR frame of the main frame, and wherein the frame generation unit generates the XOR frame including result frames by performing an XOR operation on a predetermined number of adjacent main sequence frames of the main frame, depending on the loss ratio.
