Packets transmitted from the transmission side are stored in the buffer (retransmission buffer) even after wireless transmission, and are discarded when a positive error detection result (ACK) is obtained. Therefore, if a negative error detection result is reported, the previously transmitted packet is identified accordingly and retransmitted.
- ACK positive error detection result
- a negative acknowledgment (NACK) is transmitted in step S12. Therefore, the transmission side should also confirm that fact and perform appropriate retransmission.
