Abstract: An embodiment of the present invention relates to a method in which a base station transmits a signal in a wireless communication system, comprising: a step of generating a reception acknowledgement response to the uplink data received from a terminal; and a step of mapping the reception acknowledgement response to a downlink time-frequency resource and transmitting the mapped result. The downlink time-frequency resource is located on a resource region excluding the control region indicated by a physical control format indicator channel, and associated with the index of the resource block with which the uplink data is transmitted.

Abstract: Disclosed are a method and an apparatus for receiving data using an extension carrier in a wireless access system that supports a carrier aggregation/multiple cells. A method in which a terminal receives data in a wireless access system that supports a carrier aggregation according to one embodiment of the present invention comprises: a step of receiving data starting point information indicating the symbol in a subframe at which a transmission of said data starts when data is transmitted via a secondary carrier that constitutes the carrier aggregation together with a primary carrier; and a step of receiving said data via the secondary carrier based on the data starting point information. The symbol at which the transmission of said data starts is determined from any one of a plurality of symbols including a first symbol of the subframe.
