1. A method performed by a base station in a communication system, the method comprising:
transmitting, to a terminal, a synchronization signal (SS) physical broadcast channel (PBCH) block (SSB) associated with a master information block (MIB) including first configuration information for a first control resource set (CORESET) associated with a common search space (CSS);
transmitting system information, wherein the MIB is obtained by the terminal based on the SSB, first control information for scheduling the system information is monitored by the terminal on the CSS based on a first aggregation level, and the system information is received by the terminal based on the first control information;
establishing a radio resource control (RRC) connection with the terminal based on the system information; and
transmitting, to the terminal, an RRC message including second configuration information for a second CORESET associated with a user equipment (UE) specific search space (USS), based on the RRC connection, wherein second control information for the UE is monitored by the terminal on the USS based on a second aggregation level,
wherein the first aggregation level is predetermined and includes one of 4, 8, and 16, and
wherein the second aggregation level is included in the RRC message and includes one of 1, 2, 4, 8, and 16.
