Abstract: A method and apparatus for transmitting reference signals in a relay communication system are provided. The method transmits reference signals via a type 2 relay node in a relay communication system and includes a base station (BS) allocating a plurality of antenna ports in a mutually exclusive manner so that the antenna port of the BS and the antenna port of a peripheral relay node do not overlap each other, the BS and relay node transmitting reference signals to a user equipment (UE) via the corresponding antenna ports that are mutually exclusively allocated and the BS receiving channel state information from the UE to obtain channel state information between the BS and the UE and channel state information between the relay node and the UE.

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: The present invention relates to a method and to an apparatus for transmitting/receiving data in a relay communication system. The method comprises the steps of: setting, as a guard band, the first predetermined number of symbol transmission slots of a data transmission period in a subframe resource element of a downlink channel constituted by a control signal transmission period to which a control signal is allocated and the data transmission period to which downlink data is allocated; allocating reference signals to symbols of the data transmission period; puncturing the symbols corresponding to the guard band from among the symbols to which said reference signals are allocated; and transmitting signals to which said reference signals are allocated.

Abstract: A method and a base station are described for transmitting a downlink signal in a wireless communication system. A configuration of orthogonal frequency division multiplexing (OFDM) symbols for a first partition of a subframe are transmitted through higher layer signaling. A relay-physical downlink control channel (R-PDCCH) contained in at least the first partition of the subframe is transmitted. If the R-PDCCH contains a downlink assignment, the first partition of the subframe is configured to be not used for a transmission for a physical downlink shared channel (PDSCH) corresponding to the R-PDCCH.
