1. A method of receiving data in a wireless access system supportive of carrier aggregation, the method performed by a user equipment and comprising: receiving a data starting point information indicating a symbol for starting a transmission of the data in a subframe when the data is transmitted on a secondary carrier configuring the carrier aggregation with a primary carrier; and receiving the data on the secondary carrier based on the data starting point information, wherein the symbol for starting the transmission of the data is determined as one of a plurality of symbols including a 1st symbol of the subframe, wherein the secondary carrier carries the data together with a stand-alone carrier and includes an extension carrier to which a resource is allocated by the stand-alone carrier, wherein if a downlink bandwidth of the extension carrier is equal to or smaller than 10 resource blocks, the data starting point is determined as one selected from the group consisting of the 1st, the 3rd, the 4th and the 5th symbols of the subframe, and wherein if the downlink bandwidth of the extension carrier is greater the 10 resource blocks, the data starting point is determined as one selected from the group consisting of the 1st to 4th symbols of the subframe.
