초록
An operation method of a terminal that receives a DRS in a mobile communication system operating in an unlicensed spectrum includes: receiving an SS/PBCH block included in the DRS; checking at least one monitoring occasion for a PDCCH for receiving RMSI on the basis of a PBCH included in the SS/PBCH; monitoring the at least one monitoring occasion and detecting the PDCCH for receiving the RMSI; and receiving a PDSCH including the RMSI on the basis of the detected PDCCH, wherein the at least one monitoring occasion is set to at least one symbol among symbols in front of the PDSCH and symbols behind the PDSCH. Accordingly, the DRS and data may be reliably transmitted and received in the mobile communication system operating in the unlicensed spectrum.
