Patent ID: 8547895

Claim:
A method of a relay station (RS) transmitting and receiving a signal in a wireless communication system including the RS, the method comprising: receiving frame configuration information about a RS frame from a base station (BS); configuring an uplink (UL) relay zone in which a signal is transmitted to the BS and an UL access zone in which a signal is received from a relay mobile station (MS) connected to the RS in the RS frame on the basis of the frame configuration information; transmitting a signal to the BS in the UL relay zone; and receiving a signal from the relay MS in the UL access zone, wherein the UL access zone is time-aligned with an UL access zone of a BS frame and then transmitted or transmitted before the UL access zone of the BS frame by a specific time interval, wherein when the RS switches states from a reception state to a transmission state, a first transition time (R-RTI) is located at the first orthogonal frequency division multiplexing (OFDM) symbol of the UL relay zone wherein the duration of the R-RTI is 0 or 1 OFDM symbol time, and when the RS switches states from the transmission state to the reception state, a second transition time (R-TTI) is located at the last OFDM symbol of the UL relay zone wherein the duration of the R-TTI is 0 or 1 OFDM symbol time.
