Specifically, a method by which a terminal transmits uplink control information comprises the steps of: identifying a resource region allocated to a first uplink control channel for transmitting first uplink control information, and a resource region allocated to a second uplink control channel for transmitting second uplink control information; and transmitting a specific modulation symbol to a base station using a specific uplink resource, if the transmission of the first uplink control channel and the transmission of the second uplink control channel overlap. ## Claims ### Claim 1 A method of transmitting uplink control information by a user equipment (UE) in a wireless communication system, the method comprising: identifying a resource region allocated to a first uplink control channel for transmitting first uplink control information and a resource region allocated to a second uplink control channel for transmitting second uplink control information; and transmitting, to a base station, a specific modulation symbol using a specific uplink resource, based on a transmission of the first uplink control channel overlapping a transmission of the second uplink control channel, wherein the specific uplink resource and the specific modulation symbol are configured based on a relative priority between the first uplink control channel and the second uplink control channel, wherein a location of the specific uplink resource indicates the first uplink control information, and wherein the specific modulation symbol corresponds to the second uplink control information. ### Claim 2 (depends on 1) The method of claim 1, wherein the first uplink control channel has a higher priority than the second uplink control channel. ### Claim 3 (depends on 2) The method of claim 2, wherein the first uplink control channel is configured based on a first transmission time interval, wherein the second uplink control channel is configured based on a second transmission time interval, and wherein the first transmission time interval is shorter than the second transmission time interval. ### Claim 4 (depends on 3) The method of claim 3, wherein the transmission of the specific modulation symbol using the specific uplink resource is performed based on the first time transmission interval. ### Claim 5 (depends on 1) The method of claim 1, wherein a number of symbols allocated to the first uplink control channel is configured to be less than a number of symbols allocated to the second uplink control channel. ### Claim 6 (depends on 5) The method of claim 5, wherein the first uplink control information includes at least one of Acknowledgement (ACK) information/Not-Acknowledgement (NACK) information and a scheduling request, and wherein the second uplink control information includes channel state information. ### Claim 7 (depends on 5) The method of claim 5, wherein the first uplink control channel is a short physical uplink control channel (SPUCCH), and wherein the second uplink control channel is a physical uplink control channel (PUCCH). ### Claim 8 (depends on 1) The method of claim 1, further comprising: receiving, from the base station, a first downlink shared channel, and receiving, from the base station, a second downlink shared channel, wherein the first uplink control information includes Acknowledgement (ACK)/Not-Acknowledgement (NACK) information on the first downlink shared channel, and wherein the second uplink control information includes ACK/NACK information on the second downlink shared channel. ### Claim 9 (depends on 8) The method of claim 8, wherein the specific uplink resource is one of a plurality of uplink resources predetermined for uplink control channel transmission, and wherein the predetermined plurality of uplink resources are configured based on at least one control channel element index among a first downlink control channel related to the first downlink shared channel or a second downlink control channel related to the second downlink shared channel. ### Claim 10 (depends on 9) The method of claim 9, wherein the predetermined plurality of uplink resources are configured based on an offset between a default uplink resource and uplink resources. ### Claim 11 (depends on 1) The method of claim 1, further comprising: receiving, from the base station, uplink resource configuration information for a plurality of uplink resources predetermined for uplink control channel transmission, and wherein the specific uplink resource is one of the predetermined plurality of uplink resources. ### Claim 12 (depends on 1) The method of claim 1, wherein the specific modulation symbol corresponds to a binary phase shift keying (BPSK) modulation symbol or a quadrature phase shift keying (QPSK) modulation symbol. ### Claim 13 A user equipment (UE) for transmitting uplink control information in a wireless communication system, the UE comprising: a transmitter and a receiver for transmitting and receiving a wireless signal, and a processor functionally connected to the RF unit, wherein the processor is configured to control to: identify a resource region allocated to a first uplink control channel for transmitting first uplink control information and a resource region allocated to a second uplink control channel for transmitting second uplink control information; and transmitting, to a base station, a specific modulation symbol using a specific uplink resource, based on a transmission of the first uplink control channel overlapping a transmission of the second uplink control channel, wherein the specific uplink resource and the specific modulation symbol are configured based on a relative priority between the first uplink control channel and the second uplink control channel, wherein a location of the specific uplink resource indicates the first uplink control information, and wherein the specific modulation symbol corresponds to the second uplink control information. ### Claim 14 (depends on 13) The UE of claim 13, wherein the first uplink control channel has a higher priority than the second uplink control channel. ### Claim 15 (depends on 13) The UE of claim 13, wherein a number of symbols allocated to the first uplink control channel is configured to be less than a number of symbols allocated to the second uplink control channel.
