METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING A SIGNAL THROUGH A RELAY NODE IN A WIRELESS COMMUNICATION SYSTEM IN WHICH A CARRIER AGGREGATION METHOD IS APPLIED

摘要

A method and an apparatus for enabling a relay node to transmit a signal to a macro base station and to receive the signal from the macro base station in a wireless communication in which a carrier aggregation method is applied are disclosed in the present application. Specifically, the method comprises a step of receiving a downlink control channel in the first sub-frame of a main component carrier wave; and a step of receiving a data channel on a second sub-frame and the first sub-frame based on the control information including the downlink control channel. The data channel is received in the second sub-frame through one or more sub-component carrier waves. The control information includes one or more sub-frame identifiers in order to identify the sub-frames and an carrier wave identifier for identifying the component carrier wave.
