Patent ID: 8259644

Claim:
A method for transmitting and receiving data by a Base Station (BS) in a communication system, the method comprising: determining a location of a Mobile Station (MS); determining a transmission/reception scheme for data transmission and reception to/from the MS according to the location of the MS; and transmitting and receiving data to/from the MS using the determined transmission/reception scheme; wherein the MS is located in at least one of a cell's inner region and a cell's outer region, and further wherein the cell's inner region has a radius that is adjusted according to an interference level between adjacent cells and the cell's outer region is defined by excepting the cell's inner region from the entire cell region, wherein the determining of the transmission/reception scheme comprises: when the MS is located in the cell's outer region, determining whether the MS transmits and receives a signal using a Relay Station (RS) located in the cell's inner region; and determining the transmission/reception scheme as a time division duplex scheme when the MS transmits and receives a signal using the RS, wherein a frequency applied to the time division duplex scheme between the MS and the RS is a second frequency, and a frequency applied to the time division duplex scheme between the BS and the RS is a first frequency which is different from the second frequency.
