A method for receiving feedback information by a user equipment (UE) includes: receiving scheduling information from a base station through a first downlink component carrier linked with a first uplink component carrier; determining resources on a second uplink component carrier other than the first uplink component carrier using said scheduling information, wherein said scheduling information allows cross-carrier scheduling which schedules the resources on the second uplink component carrier; transmitting data to the base station through the determined resources on the second uplink component carrier; determining a PHICH (a Physical Hybrid ARQ Indicator Channel) resource to receive feedback information for the data transmitted on the second uplink component carrier, wherein the PHICH resource is predetermined as that of the first downlink component carrier in which the scheduling information was received; and receiving the feedback information from the base station through the determined PHICH resource.
