Further, the UCI is hybrid automatic repeat request (HARQ) feedback information of multiple downlink cells. The method also includes transmitting, to the BS, the UCI on a PUCCH resource. In addition, the PUCCH resource is mapped to multiple resource block (RB) pairs, the multiple RB pairs include RBs included in a first slot and RBs included in a second slot, the RBs included in the first slot are consecutive RBs to each other, and the RBs included in the second slot are consecutive RBs to each other. ## Claims ### Claim 1 A method of transmitting, by a user equipment (UE), uplink control information (UCI) in a wireless communication system, the method comprising: receiving, from a base station (BS), physical uplink control channel (PUCCH) resource information for the UCI, wherein the UCI is hybrid automatic repeat request (HARQ) feedback information of multiple downlink cells; and transmitting, to the BS, the UCI on a PUCCH resource, wherein the PUCCH resource is mapped to multiple resource block (RB) pairs, wherein the multiple RB pairs include RBs included in a first slot and RBs included in a second slot, wherein the RBs included in the first slot are consecutive RBs to each other, and the RBs included in the second slot are consecutive RBs to each other, and wherein a long demodulation reference signal (DMRS) is generated for the entirety of the multiple RB pairs, or the entirety of specific RB pairs. ### Claim 2 (depends on 1) The method of claim 1, wherein the HARQ feedback information includes a HARQ feedback for each cell of the multiple downlink cells. ### Claim 3 (depends on 1) The method of claim 1, wherein the same orthogonal cover code (OCC) index is used in each of the multiple RB pairs. ### Claim 4 (depends on 1) The method of claim 1, wherein the multiple downlink cells include multiple cell groups (CGs), and Reed-Muller (RM) coding is separately performed on UCIs by cell groups or is collectively performed on the entire cell groups. ### Claim 5 (depends on 4) The method of claim 4, wherein when the UCIs are separately coded by cell groups, single RM coding or dual RM coding is performed depending on the number of bits of the UCIs divided by cell groups. ### Claim 6 (depends on 5) The method of claim 5, wherein when the UCIs are separately RM-coded and output by cell groups, RM interleaving is not performed on coded bits of the output UCIs. ### Claim 7 (depends on 4) The method of claim 4, wherein when there is no scheduling of UCI transmission regarding a specific cell group among the multiple cell groups, UCI transmission regarding the specific cell group without scheduling is dropped. ### Claim 8 (depends on 4) The method of claim 4, wherein when single coding is performed on the entire UCIs, the UCIs are divided to correspond to a number of PUCCH resources allocated to the UE. ### Claim 9 (depends on 8) The method of claim 8, wherein single RM coding or dual RM coding is performed on each of the divided UCIs in consideration of the number of bits of each of the divided UCIs. ### Claim 10 (depends on 9) The method of claim 9, wherein RM interleaving is performed on coded bits of each UCI output through the RM coding. ### Claim 11 A method of receiving, by a base station (BS), uplink control information (UCI) in a wireless communication system, the method comprising: transmitting, to a user equipment (UE), physical uplink control channel (PUCCH) resource information for the UCI, wherein the UCI is hybrid automatic repeat request (HARQ) feedback information of multiple downlink cells; and receiving, from the UE, the UCI on a PUCCH resource, wherein the PUCCH resource is mapped to multiple resource block (RB) pairs, wherein the multiple RB pairs include RBs included in a first slot and RBs included in a second slot, wherein the RBs included in the first slot are consecutive RBs to each other, and the RBs included in the second slot are consecutive RBs to each other, and wherein a long demodulation reference signal (DMRS) is generated for the entirety of the multiple RB pairs, or the entirety of specific RB pairs. ### Claim 12 (depends on 11) The method of claim 11, wherein the HARQ feedback information includes a HARQ feedback for each cell of the multiple downlink cells. ### Claim 13 (depends on 11) The method of claim 11, further comprising: transmitting, to the UE, control information related to determination of the PUCCH resource, wherein the control information includes at least one of candidate list information of the PUCCH resource or a specific field for a specific PUCCH resource for transmitting the UCI among candidates of the PUCCH resource. ### Claim 14 (depends on 13) The method of claim 13, wherein the specific field is set to be the same for every cell group. ### Claim 15 (depends on 11) The method of claim 11, further comprising: transmitting, to the UE, downlink control information (DCI) including a transmit power control (TPC) command of the PUCCH resource through a specific cell among the multiple downlink cells. ### Claim 16 A user equipment (UE) configured to transmit uplink control information (UCI) in a wireless communication system, the UE comprising: at least one transceiver configured to transmit and receive a radio signal; and at least one processor functionally connected to the at least one transceiver, wherein the at least one processor is configured to: control the at least one transceiver to receive, from a base station (BS), physical uplink control channel (PUCCH) resource information for the UCI, wherein the UCI is hybrid automatic repeat request (HARQ) feedback information of multiple downlink cells; and control the at least one transceiver to transmit, to the BS, the UCI on a PUCCH resource, wherein the PUCCH resource is mapped to multiple resource block (RB) pairs, wherein the multiple RB pairs include RBs included in a first slot and RBs included in a second slot, wherein the RBs included in the first slot are consecutive RBs to each other, and the RBs included in the second slot are consecutive RBs to each other, and wherein a long demodulation reference signal (DMRS) is generated for the entirety of the multiple RB pairs, or the entirety of specific RB pairs. ### Claim 17 (depends on 16) The UE of claim 16, wherein the HARQ feedback information includes a HARQ feedback for each cell of the multiple downlink cells.
