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.
