    摘要: A method and an apparatus for transmitting a control signal of a relay station in a wireless communication system are provided. The relay station generates a control signal of uplink control information and performs mapping of the generated modulation symbol into a backhaul subframe that has a relay physical uplink control channel (R-PUCCH) assigned thereto. The backhaul subframe includes two slots among. Among single carrier frequency division multiple access (SC-FDMA) symbols that constitute the backhaul subframe, an orthogonal cover (OC) sequence is applied to the SC-FDMA symbol which the modulation symbol has been mapped into, and later the backhaul subframe is transmitted. The generated modulation symbol is mapped according to the same pattern as the two slots.
