A wireless communication method for transmitting and receiving data by setting a relay link in a broadband wireless short-range communication network is provided. A source apparatus obtains relay performance information of a destination apparatus, searches for serviceable relay apparatuses, and receives service period (SP) resource allocation information. 131, 132 to perform beam forming to obtain the channel state, perform beam forming to the destination device 140 to obtain the channel state between the devices, and use the relay based on the obtained channel state information. The device 130, 131, 132 is selected, a response is received by requesting the presence / absence of the relay link through the selected relay device 130, 131, 132, and if the relay link is set, a relay link setting notification message is sent. It transmits to the access point (AP) 120. [Selection] Figure 1 |
