1. A method of receiving, by a user equipment (UE), system information (SI) in a wireless communication system supporting carrier aggregation (CA), the method comprising:
transmitting an RRC connection request message to a base station (BS);
receiving an RRC connection setup message from the BS;
transmitting an RRC connection setup complete message to the BS;
receiving, from a primary cell (PCell) of the BS, an RRC reconfiguration message related to a configuration of a secondary cell (SCell); and
receiving, from SCell of the BS, a synchronization signal (SS) based on the RRC reconfiguration message,
wherein the RRC reconfiguration message includes at least one of a master information block (MIB) of the SCell or a time point when the synchronization signal is transmitted, and
wherein an SS block related to the synchronization signal is transmitted based on beam information of the PCell and the time point when the synchronization signal is transmitted.
