Abstract:
1. A method for transmitting control information by a Base Station (BS) in a wireless communication system using Half Frequency Division Duplex (H-FDD), the method comprising: generating a control information sub-frame; mapping symbols of the control information sub-frame at a first sub-frame of a first frame; repeatedly mapping at least one symbol among the symbols of the control information at a last sub-frame of a second frame that is earlier than the first frame; transmitting the at least one symbol through the last sub-frame of the second frame and the symbols of the control information sub-frame through the first sub-frame of the first frame, and determining if there is an H-FDD Mobile Station (MS) operating in a transmission mode at a front end of the first frame, wherein the transmitting of the at least one symbol at the last sub-frame of the frame earlier than the first frame is performed when there is the H-FDD MS operating in the transmission mode at the front end of the first frame.
