1. A method of receiving, by a user equipment (UE), a paging message in a wireless communication system using an unlicensed band, the method comprising:
receiving, from a base station, a synchronization signal and physical broadcast channel block (SS/PBCH block);
receiving, from the base station, system information related to paging occasion (PO) configuration information including paging frame (PF) set information;
receiving, from the base station, control information related to paging based on the PO configuration information; and
receiving, from the base station, a paging message based on the control information,
wherein the PF set information is information for bundling of PFs,
wherein POs related to the PFs are consecutively configured in a time domain,
wherein, in the time domain, a symbol of a first PO among the POs is determined based on a configured number of symbols after a symbol of the SS/PBCH, and
wherein a Listen Before Talk (LBT) operation for the POs is performed before the first PO.
