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. Particularly, suggested are methods for retransmitting data in a machine-to-machine communication system, managing methods thereof, and apparatuses for supporting the same. The method for retransmitting data in the wireless connection system supporting the machine-to-machine communication according to one aspect of the present invention includes the steps of transmitting a transmission request message to a second device to allocate a data slot to retransmit the data in a first device among two or more peer devices; receiving a transmission response message transmitted in response to the transmission request message from the second device; and retransmitting the data to the second device through the allocated data slot.
