1. A method performed by a terminal in a wireless communication system, the method comprising:
identifying a first time-frequency resource of a first demodulation reference signal (DMRS) for a master information block (MIB) based on information carried on synchronization signals;
identifying a subcarrier spacing of the first DMRS for the MIB based on the synchronization signals;
obtaining the first DMRS for the MIB based on the first time-frequency resource; and
obtaining a second DMRS for a physical downlink shared channel (PDSCH) based on configuration information for a second time-frequency resource of the second DMRS for the PDSCH,
wherein the configuration information for the second time-frequency resource of the second DMRS for the PDSCH is received via a higher layer signaling.
