    摘要: The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and apparatus in which a base station transmits a signal to a relay in a wireless communication system. A method in which a terminal receives a downlink signal in a wireless communication system that supports carrier aggregation comprises: a step of receiving, on a first carrier, a physical downlink control channel (PDCCH) having no carrier indication information; and a step of receiving a physical downlink shared channel (PDSCH) using the scheduling information carried on the PDCCH, wherein the PDSCH is received on the first carrier in the event the PDCCH is a non-semi-persistent scheduling (SPS) PDCCH, and the PDSCH is received on a second carrier different from the first carrier in the event the PDCCH is an SPS PDCCH.

    摘要: Provided are an apparatus and method of performing an uplink hybrid automatic repeat request (HARQ) in a wireless communication system. A terminal transmits a transport block to a base station via a physical uplink shared channel (PUSCH) using uplink resource allocation and receives an ACK/NACK signal for the transport block from the base station via a physical hybrid-ARQ indicator channel (PHICH). A PHICH resource used for transmitting the PHICH is identified from a PUSCH resource used for transmitting the PUSCH, and the PUSCH resource is mapped to the PHICH resource according to an uplink element carrier through which the transport block is transmitted.

The method comprise allocating a relay zone to the relay station in a subframe and transmitting a relay control channel to the relay station by using the relay zone, wherein the subframe comprises a plurality of orthogonal frequency division multiplexing (OFDM) symbols in a time domain and a plurality of subcarriers in a frequency domain, wherein the subframe is divided into a user zone used by a user equipment in a cell and the relay zone used by the relay station, and wherein the relay zone comprises some of the plurality of subcarriers. According to the present invention, a subframe structure provides backward compatibility with a legacy wireless communication system. A relay station can effectively find a radio resource allocated to the relay station, thereby decreasing a decoding time.
