Apparatus and method for transmitting and receiving data in wireless communication system

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.

What is claimed is: 
     
         1 . A method for communicating data between a source station and a destination station, the method comprising:
 transmitting, by the source station, data through a direct route to the destination station; and   determining, at the source station, whether an Acknowledge (ACK) from the destination station is received during a first predetermined period, and upon detecting that no ACK is received during the first predetermined period, performing first relay switching at the source station and transmitting the data to the destination station via a relay route that uses a relay device.   
     
     
         2 . A method for communicating data between a source station and a destination station, the method comprising:
 receiving, at the destination station, data through a direct route from the source station; and   determining, at the destination station, whether the data from the source station is received during a second predetermined period, and upon detecting that no data is received during the second predetermined period, performing second relay switching at the destination station and receiving the data via the relay route that uses the relay device.
