1. A method to retransmit data in a wireless communication system using channel bonding, the method comprising:
- transmitting, by a wireless device, data by mapping a first set of data to a first channel of at least two channels according to the channel bonding and by mapping a second set of data to a second channel of the at least two channels according to the channel bonding;
after transmitting the first set of data and the second set of data, determining by the wireless device, whether to change the at least two channels for the data retransmission based on a channel status of the at least two channels; and
in response to determining to change the channel for the data retransmission, retransmitting, by the wireless device, the first set of data and the second set of data by changing a mapping scheme so that the first set of data is mapped to the second channel and the second set of data is mapped to the first channel,wherein retransmitting the data comprises transmitting channel change information by changing the channel change information corresponding to the changed channel in a header of the retransmitted data.

8. A wireless device comprising:
a controller configured to; control a transmission of data by mapping a first set of data to a first channel of at least two channels according to a channel bonding and by mapping a second set of data to a second channel of the at least two channels according to the channel bonding, after transmitting the first set of data and the second set of data, determine whether to change the at least two channels for data retransmission based on a channel status of the at least two channels, and in response to determining to change the channel for the data retransmission, retransmit the first set of data and the second set of data by changing a mapping scheme so that the first set of data is mapped to the second channel and the second set of data is mapped to the first channel, wherein the controller is configured to control a transmission of channel change information by changing the channel change information corresponding to the changed channel in a header of the retransmitted first set of data and second set of data. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 17)

18. A method to retransmit data in a wireless communication system using channel bonding, the method comprising:
-
transmitting, by a wireless device, data by mapping a first set of data to a first channel of at least two channels and by mapping a second set of data to a second channel of the at least two channels; detecting, by the wireless device, retransmission data; mapping, by the wireless device, channel for retransmission of the first set of data and the second set of data, wherein the channel for retransmission is mapped by crossing the respective channel used for transmission of the first set of data and the second set of data; and retransmitting, by the wireless device, at least one of the first set of data and the second set of data through the respective channel, wherein retransmitting the data comprises transmitting channel change information by changing the channel change information corresponding to the mapped channel in a header of the retransmitted data. - View Dependent Claims (19)

20. A wireless device comprising:
-
a communication module; and a processor connected functionally to the communication module, the processor is configured to; control to transmit data by mapping a first set of data to a first channel of at least two channels and by mapping a second set of data to a second channel of the at least two channels, detect retransmission data, map a channel for retransmission of the first set of data and the second set of data, wherein the channel for retransmission is mapped by crossing the respective channel used for transmission of the first set of data and the second set of data, and retransmit at least one of the first set of data and the second set of data through the respective channel, wherein the processor is further configured to control a transmission of channel change information by changing the channel change information corresponding to the mapped channel in a header of the retransmitted first set of data and second set of data. - View Dependent Claims (21)
