METHOD OF RETRANSMITTING DATA IN A WIRELESS CONNECTION SYSTEM SUPPORTING MACHINE-TO-MACHINE COMMUNICATION, AND DEVICE FOR SUPPORTING SAME

摘要

The present invention relates to a wireless connection system, and in particular, relates to methods of retransmitting data in a machine-to-machine communication system, methods of managing the data, and devices for supporting machine-to-machine communication. As one aspect of the present invention, the method of retransmitting data in the wireless connection system supporting the machine-to-machine communication may include: allocating a data slot for retransmitting data from a first machine, from among two or more peer machines, by transmitting a transmit request message to a second machine; receiving a transmit response message transmitted form the second machine in response to the transmit request message; and retransmitting data to the second machine through the allocated data slot.

1. A method for retransmitting data in a wireless access system supporting Machine to Machine (M2M) communication, the method comprising:
transmitting a transmission request message to a second device by a first device among two or more peer devices, to allocate a data slot for a data retransmission; receiving a transmission response message in response to the transmission request message from the second device; and retransmitting data in an allocated data slot to the second device.
