Patent ID: 8718010

Claim:
A method of transmitting a frame of a relay station (RS) in a wireless communication system utilizing the RS, the method comprising: receiving frame configuration information related to an RS frame from a base station (BS); configuring a frame comprising a downlink (DL) access zone for transmitting a signal to a relay user equipment (UE), a DL relay zone for receiving a signal from the BS, an uplink (UL) access zone for receiving a signal from the relay UE connected to the RS, a UL relay zone for transmitting a signal to the BS, and a transition gap; and transmitting a signal in at least the DL access zone or the UL relay zone, wherein the transition gap is a switching time between a transmission operation and a reception operation of the RS and is included in at least the DL access zone or the UL relay zone, and wherein a DL access zone subframe that includes the transmission gap is formed by a type-3 subframe consisting of 5 symbols, among a type-1 subframe consisting of 6 symbols, a type-2 subframe consisting of 7 symbols, a type-3 subframe consisting of 5 symbols and a type-4 subframe consisting of 9 symbols, when the transition gap is included in a last symbol of the DL access zone and a corresponding DL access zone subframe of the BS is a type-1 subframe consisting of 6 symbols.
