Method for restoring error in wireless device

The present invention in particular, incremental redundancy of the error recovery method in a wireless device (Incremental Redundancy: IR) the application to increase the packet reception success rate by improving the error recovery process in the wireless LAN Further, retransmission for use in the current WLAN (retransmission) when it is an object to to reduce the packet transmission time by increasing the decoding efficiency of a receiver channel reducing the number of retransmissions. The present invention for this purpose is provided a packet transmission method in a wireless device, the steps and, the step of determining a first packet transmission speed, and a step of transmitting the packet to the determined transmission rate, the transmission packet to prepare packet transfer If the acknowledgment (ACK) signal is received, it characterized in that the configuration to determine a channel coding rate and the channel code set to perform the step of retransmitting the packet.
