1. A method performed by a reduced capability (redcap) terminal in a wireless communication system, the method comprising:
receiving, from a base station, configuration information on a downlink bandwidth part (BWP) via higher layer signaling;
identifying whether the configuration information includes information on an additional synchronization signal block (SSB) related to the redcap terminal; and
in case that the configuration information includes the information on the additional SSB, receiving, from the base station, one or more additional SSBs, wherein the additional SSB is quasi co-located (QCLed) with at least one of a demodulation reference signal (DMRS) port of a physical downlink control channel (PDCCH) or a DMRS port of a physical downlink shared channel (PDSCH),
wherein in case that the configuration information does not include the information on the additional SSB, an SSB for an initial access is QCLed with at least one of the DMRS port of the PDCCH or the DMRS port of the PDSCH.
