Method and device for transmitting control information in wireless communication system

A method of receiving a signal by a base station from a terminal in a wireless communication system supporting a plurality of serving cells, the method comprising:

• transmitting, to the terminal, at least one physical channel including at least one physical downlink control channel (PDCCH) on the plurality of serving cells;
• and
• receiving, from the terminal, first control information resulting from performing a bundling on at least a portion of control information on the terminal's reception of the at least one physical channel,
• wherein the first control information is received using a physical uplink control channel (PUCCH) resource corresponding to second control information,
• wherein the second control information is associated with a PDCCH last detected by the terminal among the at least one PDCCH,
• wherein, when the last detected PDCCH is transmitted on a primary cell (PCell) of the plurality of serving cells, the PUCCH resource is determined using at least one control channel element (CCE) index configuring the last detected PDCCH, and
• wherein, when the last detected PDCCH is transmitted on a secondary cell (SCell) of the plurality of serving cells, the PUCCH resource is determined using ACK resource indicator (ARI) information transmitted by the base station.

A terminal for transmitting control information to a base station in a wireless communication system supporting a plurality of serving cells, the terminal comprising:

• a receiver for receiving, from the base station, at least one physical channel including at least one physical downlink control channel (PDCCH) on the plurality of serving cells;
• a transmitter for transmitting, to the base station, first control information resulting from performing a bundling on at least a portion of control information on reception of the at least one physical channel;
• and
• a processor for controlling transmission of the first control information to the base station using a physical uplink control channel (PUCCH) resource corresponding to second control information,
• wherein the second control information is associated with a PDCCH last detected by the terminal among the at least one PDCCH,
• wherein, when the last detected PDCCH is received on a primary cell (PCell) of the plurality of serving cells, the PUCCH resource is determined using at least one control channel element (CCE) index configuring the last detected PDCCH, and
• wherein, when the last detected PDCCH is received on a secondary cell (SCell) of the plurality of serving cells, the PUCCH resource is determined using ACK resource indicator (ARI) information received from the base station.
