Provided is a method for preventing consecutive packet errors in a transmitter by combining a hybrid automatic repeat request (HARQ) type II with a selective automatic repeat request (ARQ), including: transmitting a data packet from the transmitter to a receiver; when a negative acknowledgement (NACK) packet corresponding to the data packet is received from the receiver, checking stored information in the NACK packet wherein the stored information represent whether or not the data packet is stored in a buffer; when the data packet is stored in the buffer, transmitting a packet having parity bits to the receiver and storing the data packet in a retransmission queue; and when the data packet is not stored in the buffer, re-transmitting the data packet and maintaining the data packet stored in a transmission queue.
