Method and apparatus for RMSI reception from a neighboring cell

1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising:

detecting a synchronization signal and physical broadcast channel (SS/PBCH) block;

in case that the SS/PBCH block is not located on a frequency location of a synchronization raster entry, identifying an offset from a smallest resource block (RB) index of control resource set (CORESET) for a Type0-PDCCH to a smallest RB index of a common RB overlapping with a first RB of the SS/PBCH block based on a sum of a first offset and a second offset; and

monitoring the Type0-PDCCH based on the identified offset,

wherein the first offset is configured based on a master information block (MIB) in the SS/PBCH block, and

wherein the second offset is identified based on an offset from the smallest RB index of the common RB overlapping with the first RB of the SS/PBCH block to a smallest RB index of a common RB overlapping with a first RB of another SS/PBCH block hypothetically located on the frequency location of the synchronization raster entry.

12. The UE of claim 7 , wherein the first offset and the second offset are defined with respect to subcarrier spacing (SCS) of the CORESET for the Type0-PDCCH.

13. A base station (BS) in a wireless communication system, the BS comprising:

a transceiver; and

at least one processor operably connected to the transceiver and configured to configure an offset identified from a smallest resource block (RB) index of control resource set (CORESET) for a Type0-PDCCH to a smallest RB index of a common RB overlapping with a first RB of a synchronization signal and physical broadcast channel (SS/PBCH) block based on a sum of a first offset and a second offset in case that is not located on a frequency location of a synchronization raster entry,

wherein the Type0-PDCCH is monitored based on the identified offset,
