1. A method of transmitting and receiving a signal, performed by a user equipment (UE), in a wireless communication system, the method comprising:
receiving downlink data on a primary cell (PCell), wherein a value of a downlink assignment index (DAI) included in Downlink Control Information (DCI) for scheduling the downlink data is 1; and
transmitting hybrid automatic repeat request (HARQ) information for the downlink data,
wherein based on a scheduling request (SR) transmission being configured in a subframe in which the HARQ information is transmitted, (i) the HARQ information and (ii) an SR are transmitted together in the subframe, and
wherein based on multi-radio dual connectivity (MR-DC) between evolved universal terrestrial radio access (E-UTRA) and new radio (NR) being configured for the UE, (i) the HARQ information and (ii) the SR are transmitted in a resource related to physical uplink control channel (PUCCH) format 3, and
wherein, based on dual connectivity (DC) is configured for the UE and the DC being not the MR-DC, (i) the HARQ information and (ii) the SR are transmitted in a resource related to PUCCH format 1b.
