Abstract: A method and a relay node are described for transmitting and receiving data. The relay node receives a downlink data in a subframe n−k from a base station. The subframe n−k is configured as a multicast broadcast single frequency network (MBSFN) subframe by the relay node. The relay node transmits to the base station, in response to receiving the downlink data in the subframe n−k, an acknowledgement (ACK)/negative acknowledgement (NACK) in an uplink subframe n, where n is an index number of the uplink subframe for transmitting the ACK/NACK. A value of n is associated with a parameter indicating subframe configuration related with at least one hybrid automatic repeat request (HARM) process between the relay node and the base station. The value of k is equal to or greater than 4.

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 high layer signaling. A relay-physical downlink control channel (R-PDCCH) contained in 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 physical downlink shared channel (PDSCH) transmission.

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 relates to a data transmission/receiving method and apparatus in a relay communication system. In particular, the data transmission/receiving method through a backhaul link between a base station and a relay node in a relay communication system comprises: composing a backhaul subframe including a control signal transmission period to which a control signal is allocated and a backhaul signal transmission period to which a backhaul signal is allocated and then allocating the backhaul signal; transmitting configuration information about the backhaul subframe, the information containing symbol position or size data of the backhaul signal transmission period, to the relay node through an upper layer signal; and transmitting the backhaul signal having been allocated through the backhaul subframe to the relay node.
