A method and apparatus supporting multiple carriers is provided. A user equipment receives a self-control format indicator (CFI) indicating a size of a control region of a first carrier by using the first carrier. The user equipment receives downlink control information (DCI) comprising a cross-CFI indicating a size of a control region of a second carrier over a first downlink control channel in the control region of the first carrier. The user equipment monitors a second downlink control channel in the control region of the second carrier.

A method and apparatus for transmitting an uplink control signal in a wireless communication system are provided. A user equipment spreads a third control signal by using either a reference signal sequence of a first control signal or a reference signal sequence of a second control signal, thereby multiplexing the third control signal to the first and second control signals. Thus, a payload of a control channel can be increased.

The present invention discloses a method in which a base station transmits a downlink signal in a wireless communication system. In detail, the method comprises the following steps: allocating a transmitting resource to data symbols for transmitting downlink signals, in the direction of increasing a frequency index; and transmitting the downlink signal to a terminal, using the allocated resource. The frequency band of preset orthogonal frequency division multiplexing (OFDM) symbols, from among the transmitting resource, contains a control domain and a segment band. The step of allocating the transmitting resource comprises the step of puncturing the data symbol using a control channel, to which the control domain contained in the preset OFDM symbols is allocated.

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.
