Abstract: Methods for transmitting and receiving data of a station includes setting a direct route to a corresponding station and a relay route to a relay device, selecting one route as between the direct route and relay route, and transmitting and receiving data through the selected route. A non-transitory computer-readable storage medium may store a program including instructions to cause a computer to perform the method. The setting may be performed by a processor and the transmitting and receiving may be performed respectively by a transmitter and a receiver.
