Abstract:
1. A method of transmitting and receiving data in a wireless access system for supporting carrier aggregation, the method comprising: transmitting downlink control information (DCI) for scheduling downlink data on a physical downlink control channel (PDCCH) in a first subframe; and transmitting the downlink data scheduled according to the DCI on a physical downlink shared channel (PDSCH) in a second subframe which is not the first subframe, wherein the DCI comprises a subframe indicator field (SIF) indicating the second subframe for transmission of the downlink data, wherein same bits of the SIF indicate the second subframe differently, for a case when a direct mapping method is applied and for a case when a radio resource control (RRC) configured method is applied, and wherein the direct mapping method is a scheme for determining the second subframe by using only the SIF, and the RRC configured method is a scheme for determining the second subframe by referring to a RRC signaling indicating a subframe.
