    摘要: Provided is a method for transmitting signals in a relay station. In detail, the method for transmitting signals in a relay station of a wireless communication system using a plurality of subframes including a plurality of OFDM symbols or SC-FDMA symbols comprises the steps of: receiving bitmap information on a backhaul downlink subframe from the relay station; obtaining control information on a subframe that is not used for a backhaul downlink; and repeatedly transmitting channel state information to the relay station on the basis of a virtual index indicating only a backhaul uplink subframe, wherein the backhaul uplink subframe is determined according to the control information and the bitmap information.

    摘要: A method and apparatus for transmitting a signal to a relay at a Base Station (BS) in a wireless communication system are disclosed. The method includes mapping a Reference Signal (RS) to a subframe having two slots, and transmitting the subframe to the relay. Each of the slots includes a plurality of consecutive resource elements over which the RS can be spread and the plurality of consecutive resource elements are overlapped with a last Orthogonal Frequency Division Multiplexing (OFDM) symbol of the slot. If a last OFDM symbol of the subframe is not available to the relay, the RS is transmitted only in a first slot of the subframe.
