1. A control method performed by a terminal in a wireless communication system, the method comprising:
receiving, from a base station, radio resource control (RRC) signaling for a signal measured by the terminal, the RRC signaling including resource information related with synchronization signal/broadcast block (SSB), the resource information corresponding to slots or symbols to which the signal measured by the terminal is transmitted;
identifying, based on the resource information, a transmission interval of the signal measured by the terminal;
identifying beam information corresponding to a set of beams between a set of wide beams and a set of narrow beams which can be formed by the terminal, wherein the set of wide beams each has a first width and the narrow set of beams each has a second width narrower than the set of wide beams;
in case that the set of beams is used for receiving another SSB from another base station, selecting the set of wide beams between the set of wide beams and the set of narrow beams; or
in case that the set of beams is used for at least one of a physical downlink control channel (PDCCH) signal or a physical downlink shared channel (PDSCH) signal, selecting the set of narrow beams between the set of wide beams and the set of narrow beams; and
receiving, based on the transmission interval and the beam information, the SSB or the at least one of the PDCCH signal or the PDSCH signal.
