System and method for retransmitting received data using index coding and statistical characteristics
A method for transmitting packets by a transmitter in a wireless communication network and retransmitting the packets not received correctly by receivers is discussed. The method includes transmitting the packets to at least two receivers, receiving reception acknowledgement response signals including ACK or NACK signals for the packets transmitted to the receivers, analyzing patterns of the received reception acknowledgement response signals in accordance with a number of the ACK or NACK signals, differently index coding the packets which are not received correctly by each receiver, and retransmitting the index-coded packets.
