Abstract: A method is provided for transmitting a downlink signal by a base station in a wireless communication system. A configuration of orthogonal frequency division multiplexing (OFDM) symbols is transmitted for a first partition of a subframe through higher layer signaling, and a Relay-Physical Downlink Control Channel (R-PDCCH) contained in at least the first partition of the subframe is also transmitted. If the R-PDCCH contains a downlink assignment, the first partition of the subframe is configured not to be used for a transmission of a Physical Downlink Shared Channel (PDSCH) corresponding the R-PDCCH.

Abstract: The present invention provides a method for avoiding interference resulting from data transmission between an adjacent second base station and a second relay station placed within the coverage of the adjacent second base station. The method for avoiding interference comprises: receiving the radio resource scheduling information from the adjacent second base station; checking the radio resources used in the data transmission between the adjacent second base station and the second relay station based on the received radio resource scheduling information; and scheduling at least one radio resource among uplink radio resources and downlink radio resources for at least one first terminal and at least one first relay station which are connected to a first base station in order to avoid interference with the checked radio resource if the radio resource used in the data transmission from the second base station to the second relay station is checked as the uplink resource or if the radio resource used in the data transmission from the second relay station to the second base station is checked as the downlink resource.

Abstract: A method and apparatus of transmitting a reference signal in a wireless communication system is provided. The method includes generating a precoded reference signal or a non-precoded reference signal in accordance with a rank, and transmitting the generated reference signal. Uplink transmission using multiple transmit antennas is supported through reference signal design and related control signaling.
