Abstract
A method of operating a relay station in a wireless communication system is provided. The method includes operating in a first mode comprising a first sub-mode and a second sub-mode, in the first sub-mode a first downlink and a first uplink between a base station and the relay station being simultaneously activated, in the second sub-mode a second downlink and a second uplink between the relay station and a mobile station being simultaneously activated, and operating in a second mode comprising a third sub-mode and a fourth sub-mode, in the third sub-mode the first downlink and the second uplink being simultaneously activated, in the fourth sub-mode the first uplink and the second downlink being simultaneously activated.

16. A method of operating a base station (BS) in a wireless communication system, the method comprising:
-
transmitting subframe configuration information to a relay station (RS); and transmitting a signal to the RS in a downlink subframe configured based on the subframe configuration information, wherein a first downlink transmission, from the BS to the RS, and a second downlink transmission, from the RS to an user equipment (UE), are performed at different times and in a downlink frequency band, wherein the downlink subframe for transmitting the signal to the RS is configured per a specific number of subframes with an exception of a first downlink subframe, a fifth downlink subframe, a sixth downlink subframe and a tenth downlink subframe of a frame, and wherein the frame comprises 10 downlink subframes. - View Dependent Claims (17, 18, 19)
