Method and apparatus for allocating resource in wireless communication system

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.

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.
