Provided are a method for receiving information on a relay node zone and reference signals for a relay node from a base station, and a relay node device using same. The relay node can receive information on at least one start point from the start points of a Relay-Physical Downlink Control Channel (R-PDCCH) and a Relay-Physical Downlink Shared Channel (R-PDSCH) for transmitting a signal from a base station to a relay node in a specific downlink subframe. Alternatively, the relay node can implicitly recognize the start points of the R-PDCCH and R-PDSCH set in advance. The relay node can recognize a signal from the base station in the specific downlink subframe based on the start point information after the time corresponding to at least one of the start points of the R-PDCCH and R-PDSCH. Also, the relay node can decode signals transmitted from a base station after the corresponding timing.

A method for identifying a MBSFN (Multimedia Broadcast multicast service Single Frequency Network) subframe at a user equipment (UE) in a wireless communication system is disclosed. Receiving module may receive receiving a subframe type information from an base station (BS). Receiving module may receive type information of the MBSFN subframe. The identifying module may identify an index of a MBSFN subframe based on the received subframe type information. The identifying module may identify a type of the MBSFN subframe based on the received type information of the MBSFN subframe. Decoding module may decode only a physical control channel region of the MBSFN subframe based on the identified type of the MBSFN subframe. Alternatively, Decoding module may decode the MBSFN subframe if the identified type of the MBSFN subframe is a decodable type or a known type.

Disclosed are a base station apparatus and a repeater apparatus for transceiving signals in a wireless communication system. The repeater apparatus comprises: a receiver which receives a signal from a base station through a first region of a first downlink subframe in a component carrier that supports first and second wireless communication schemes; and a transmitter which transmits, through a second region of the first downlink subframe, a signal to one or more terminals of one or more first type of terminals which use the first wireless communication scheme and one or more second type of terminals which use the second wireless communication scheme, simultaneously with said reception of the signal. Here, the first region and the second region are multiplexed in the first downlink subframe in accordance with a frequency division multiplexing (FDM) scheme.

A method of performing hybrid automatic repeat request (HARQ) by a source station in a wireless communication system is provided. The method includes: transmitting data to a destination station at a transmission start time; receiving an acknowledgment (ACK) or negative-acknowledgement (NACK) signal for the data from the destination station after a first transmission time interval elapses from the transmission start time; and upon receiving the NACK signal, retransmitting the data after a second transmission time interval elapses from the transmission start time, wherein the second transmission time interval is one transmission time interval selected from a plurality of predetermined transmission time intervals. Accordingly, the wireless communication system can perform a heterogeneous HARQ process in which an HARQ period, an ACK/NACK transmission start time, and the like are different.
