METHOD FOR COOPERATIVE COMMUNICATION IN WIRELESS LANS

摘要

PURPOSE: A cooperative communication method in wireless LANs is provided to guarantee an additional transmission chance for a relay device, thereby providing suitable compensation for a relay operation. CONSTITUTION: Transmitting device 1 obtains a transmission chance. Transmission device 1 transmits the next RTS(Request To Send) frame to a receiving device. The receiving device determines whether to perform cooperative communication based on a possible transfer rate of transmitting device 1. The receiving device transmits a cCTS(cooperative Clear To Send) frame to transmitting device 1. Transmitting device 1 receives an riCTS(relay i Clesr To Send) frame from candidate relay devices. Transmitting device 1 selects an optimal relay device.
