Abstract: 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.

Abstract: Disclosed is a data transmission method in a mobile communication system. The data transmission method through a code sequence in a mobile communication system includes grouping input data streams into a plurality of blocks consisting of at least one bit so as to map each block to a corresponding signature sequence, multiplying a signature sequence stream, to which the plurality of blocks are mapped, by a specific code sequence, and transmitting the signature sequence stream multiplied by the specific code sequence to a receiver.
