Abstract: The present invention discloses a method and an apparatus for a terminal receiving control information, which includes a modified physical hybrid ARQ indicator channel (PHICH) configuration, through a downlink shared channel (DL-SCH), in a heterogeneous network system comprising a macro cell and a femto cell. The method for the terminal receiving the control information in the heterogeneous network system comprising the macro cell and the femto cell, according to one embodiment of the present invention, comprises the steps of: the terminal accessing the macro cell undergoing a handover to the femto cell; and receiving PHICH reconfiguration information from the femto cell through the downlink shared channel (DL-SCH), when the configuration of the physical hybrid ARQ indicator channel (PHICH) used by the terminal which has undergone the handover is modified.
