Abstract: A method and apparatus of a UE in a wireless communication system supporting a shared spectrum channel access is provided. The method and apparatus comprises: detecting a synchronization signal and physical broadcast channel block, SS/PBCH block; and determining a offset between control resource set, CORESET, for Type0-PDCCH and the SS/PBCH block as a sum of a first offset and a second offset in case that a frequency location of the detected SS/PBCH block does not corresponds to a frequency location of a synchronization raster entry, wherein the first offset is configured by a master information block, MIB, in the detected SS/PBCH block, and wherein the second offset is determined based on frequency difference between the frequency location of the detected SS/PBCH block and the frequency location of the synchronization raster entry.
