A method for transmitting uplink control information by a terminal in a wireless communication system may comprise the steps of: receiving, from a base station, information on a primary cell (Pcell) and at least one secondary cell (Scell) configured for said terminal; and transmitting the uplink control information through the specific Scell configured for said terminal when said Pcell and said Scell are set to different time division duplex (TDD) downlink (DL)/uplink (UL) configurations and said terminal is set to simultaneously transmit a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH). ## Claims ### Claim 1 A method for transmitting uplink control information by a user equipment in a wireless communication system, the method comprising the steps of: receiving, from a base station, information on a primary cell (Pcell) and at least one secondary cell (Scell) configured for the user equipment; and transmitting the uplink control information through a specific Scell configured for the user equipment when the Pcell and the Scell have their respective time division duplex (TDD) downlink (DL)/uplink (UL) configurations different from each other and the user equipment is configured to simultaneously transmit a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH). ### Claim 2 (depends on 1) The method according to claim 1, wherein the uplink control information is at least one of hybrid automatic repeat request (HARQ) feedback information, periodic channel state information (CSI) reporting information, channel quality information (CQI), precoding matrix index (PMI) information, rank indicator (RI) information, or scheduling request (SR) information. ### Claim 3 (depends on 1) The method according to claim 1, wherein the HARQ feedback information is for a physical downlink shared channel (PDSCH) of the specific Scell configured for the user equipment. ### Claim 4 (depends on 1) The method according to claim 1, wherein an interval to which the uplink control information is transmitted is allocated as a downlink subframe for the Pcell and as an uplink subframe for the specific Scell configured for the user equipment. ### Claim 5 (depends on 1) The method according to claim 1, wherein the specific Scell is any one Scell allocated to the interval to which the uplink control information will be transmitted, as the uplink subframe interval, if a plurality of Scells are configured for the user equipment. ### Claim 6 (depends on 1) The method according to claim 1, wherein the specific cell is the Scell to which the PUSCH is transmitted together with the uplink control information (UCI) when a plurality of Scells are configured for the user equipment and the uplink subframe interval for all of the plurality of the Scells is allocated to the interval to which the uplink control information will be transmitted. ### Claim 7 A user equipment for transmitting uplink control information in a wireless communication system, the user equipment comprising: a receiver configured to receive, from a base station, information on a primary cell (Pcell) and at least one secondary cell (Scell) configured for the user equipment; a processor configured to perform a control operation to transmit the uplink control information through a specific Scell configured for the user equipment when the Pcell and the Scell have their respective time division duplex (TDD) downlink (DL)/uplink (UL) configurations different from each other and the user equipment is configured to simultaneously transmit a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH); and a transmitter configured to transmit the uplink control information through the specific Scell configured for the user equipment. ### Claim 8 (depends on 7) The user equipment according to claim 7, wherein the uplink control information is at least one of hybrid automatic repeat request (HARQ) feedback information, periodic channel state information (CSI) reporting information, channel quality information (CQI), precoding matrix index (PMI) information, rank indicator (RI) information, and scheduling request (SR) information. ### Claim 9 (depends on 8) The user equipment according to claim 8, wherein the HARQ feedback information is for a physical downlink shared channel (PDSCH) of the specific Scell configured for the user equipment. ### Claim 10 (depends on 8) The user equipment according to claim 8, wherein an interval to which the uplink control information is transmitted is allocated as a downlink subframe for the Pcell and as an uplink subframe for the specific Scell configured for the user equipment. ### Claim 11 (depends on 8) The user equipment according to claim 8, wherein the specific Scell is any one Scell allocated to the interval to which the uplink control information will be transmitted, as the uplink subframe interval, if a plurality of Scells are configured for the user equipment. ### Claim 12 (depends on 8) The user equipment according to claim 8, wherein the specific cell is the Scell to which the PUSCH is transmitted together with the uplink control information when a plurality of Scells are configured for the user equipment and the uplink subframe interval for all of the plurality of the Scells is allocated to the interval to which the uplink control information will be transmitted.
