Method for cooperative communication in wireless lans

To provide adequate compensation to the device to perform a relay, and the cooperation of the wireless LAN communication method that can improve the average transmission rate of the wireless LAN while minimizing the overhead of cooperative communication is disclosed. Cooperative communication method of the wireless LAN when it is determined that the receiving device is required, steps, a cooperative communication for determining whether the cooperative communication on the basis of the transmission request signal provided from the transmission apparatus transmits the transmission acknowledgment signal to which the receiver is indicating a cooperative communication phase step and a plurality of devices to the at least one device of the transmission response and a peek (overhearing) step to listen to the signal, a plurality of devices indicating the cooperative communication for transmitting a response signal to support relaying the transmission apparatus and , the transmission apparatus is transmitted from the stage and the relay device is a transmitting apparatus for transmitting data to at least one step of selecting a relay apparatus based on a response signal for supporting a said relay received from the device, a transmission device is a relay device data By the way, the data of the relay apparatus and transmitting to the receiving apparatus. Therefore, it is possible to minimizing the overhead and improve the average throughput of the wireless LAN, by ensuring the additional transmission opportunity for performing the access point may provide the appropriate compensation for the relay to perform.
