1. A method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station (BS), a downlink signal associated with a transmit beam of the BS, wherein the downlink signal includes a synchronization signal, a control signal for a master information block (MIB), and a reference signal; and
identifying a cell identifier based on the downlink signal,
wherein a plurality of symbols of the reference signal are arranged at regular subcarrier intervals in a frequency domain,
wherein a location of the plurality of symbols arranged in the frequency domain is determined according to the cell identifier, and
wherein a sequence of the reference signal is determined according to the cell identifier.
