1. A method for transmitting uplink control information of a user equipment (UE) for which a plurality of serving cells are configured in a wireless communication system, the method comprising:

  • receiving downlink control information on at least one physical downlink control channel (PDCCH) in a first subframe through a first serving cell among the plurality of serving cells;

    receiving data on at least one physical downlink shared channel (PDSCH) in the first subframe through at least one serving cell among the plurality of serving cells based on the downlink control information; and

    transmitting acknowledgement/negative acknowledgement (ACK/NACK) indicating success or failure of decoding of the data in a second subframe,wherein the ACK/NACK is transmitted by using first resource within the second subframe when one PDSCH is received only through the first serving cell,wherein the ACK/NACK is transmitted by using a second resource within the second subframe when a plurality of PDSCHs are received through two or more serving cells from among the plurality of serving cells,wherein the first resource is allocated dynamically by a PDCCH which schedules the first serving cell, and the second resource is predetermined,wherein, among the at least one PDCCH, a PDCCH which schedules a serving cell except for the first serving cell includes PDSCH aggregate information indicating a total number of PDSCHs transmitted through the plurality of serving cells in the first subframe, andwherein the PDSCH aggregate information is transmitted through a transmission power control (TPC) field of an uplink component carrier.
