The method generates uplink control information, transmits the uplink control information to a base station using a specific PUCCH format among a plurality of physical uplink control channel (PUCCH) formats, wherein the specific PUCCH format which is used is determined on the basis of the number of symbols in the time domain used for transmission of uplink control information and the number of bits of the uplink control information. ## Claims ### Claim 1 A method for transmitting uplink control information by a User Equipment (UE) in a wireless communication system, the method comprising: receiving a higher layer signal for a plurality of physical uplink control channel (PUCCH) resources; receiving downlink control information (DCI); generating the uplink control information; and transmitting the uplink control information, based on the higher layer signal and the DCI, to a base station using a specific PUCCH format among a plurality of PUCCH formats, wherein the uplink control information comprises hybrid automatic repeat and request-acknowledge (HARQ-ACK) information, wherein the specific PUCCH format is determined based on a number of symbols used for transmission of the uplink control information in a time domain and a number of bits of the uplink control information, wherein the plurality of PUCCH formats comprise: PUCCH format 0 in which the number of symbols used for transmission of the uplink control information in the time domain is 1 or 2 and the number of bits of the uplink control information is 1 or 2, PUCCH format 1 in which the number of symbols used for transmission of the uplink control information in the time domain is 4 or more and the number of bits of the uplink control information is 1 or 2, PUCCH format 2 in which the number of symbols used for transmission of the uplink control information in the time domain is 1 or 2, and the number of bits of the uplink control information is more than 2, PUCCH format 3 or PUCCH format 4 in which the number of symbols used for transmission of the uplink control information in a time domain is 4 or more and the number of bits of the uplink control information is more than 2, wherein the DCI comprises (i) a PUCCH resource indicator field informing of a PUCCH resource among the plurality of PUCCH resources and (ii) a slot timing indicator field informing of a slot where the specific PUCCH format is to be transmitted, and wherein the specific PUCCH format is transmitted based on the PUCCH resource informed by the PUCCH resource indicator field in the slot informed by the slot timing indicator field. ### Claim 2 (depends on 1) The method of claim 1, wherein each of the plurality of PUCCH resources comprises at least one of a parameter related to a first symbol to which a PUCCH is transmitted, a parameter related to a first physical resource block (PRB) to which a PUCCH is transmitted, a parameter related to the number of symbols to which a PUCCH is transmitted, a parameter related to an orthogonal cover code (OCC), or a parameter related to cyclic shift (CS). ### Claim 3 (depends on 1) The method of claim 1, further comprising receiving data from the base station. ### Claim 4 (depends on 3) The method of claim 3, wherein the HARQ-ACK information is acknowledge/negative-acknowledgement (ACK/NACK) for the data. ### Claim 5 (depends on 1) The method of claim 1, wherein the specific PUCCH format is transmitted within a slot comprising 14 symbols in the time domain. ### Claim 6 (depends on 1) The method of claim 1, wherein the PUCCH format 3 does not support multiplexing with PUCCH formats transmitted by other UEs. ### Claim 7 (depends on 1) The method of claim 1, wherein the PUCCH format 4 supports multiplexing with PUCCH formats transmitted by other UEs. ### Claim 8 A user equipment (UE) configured to operate in a wireless communication system, the UE comprising: a transceiver configured to transmit and receive radio signals; and a processor configured to operate in conjunction with the transceiver, wherein the processor is further configured to: receive a higher layer signal for a plurality of physical uplink control channel (PUCCH) resources; receive downlink control information (DCI); generate uplink control information, and transmit the uplink control information, based on the higher layer signal and the DCI, to a base station using a specific PUCCH format among a plurality of PUCCH formats, wherein the uplink control information comprises hybrid automatic repeat and request-acknowledge (HARQ-ACK) information, wherein the specific PUCCH format is determined based on a number of symbols used for transmission of the uplink control information in a time domain and a number of bits of the uplink control information, wherein the plurality of PUCCH formats comprise: PUCCH format 0 in which the number of symbols used for transmission of the uplink control information in the time domain is 1 or 2 and the number of bits of the uplink control information is 1 or 2, PUCCH format 1 in which the number of symbols used for transmission of the uplink control information in the time domain is 4 or more and the number of bits of the uplink control information is 1 or 2, PUCCH format 2 in which the number of symbols used for transmission of the uplink control information in the time domain is 1 or 2, and the number of bits of the uplink control information is more than 2, PUCCH format 3 or PUCCH format 4 in which the number of symbols used for transmission of the uplink control information in a time domain is 4 or more and the number of bits of the uplink control information is more than 2, wherein the DCI comprises (i) a PUCCH resource indicator field informing of a PUCCH resource among the plurality of PUCCH resources and (ii) a slot timing indicator field informing of a slot where the specific PUCCH format is to be transmitted, and wherein the specific PUCCH format is transmitted based on the PUCCH resource informed by the PUCCH resource indicator field in the slot informed by the slot timing indicator field.
