Method and apparatus of NR RMSI coreset configuration in MIB

A user equipment (UE) comprising:

• at least one transceiver;
• and
• at least one processor, wherein the at least one processor is configured to:
• receive, from a base station, a synchronization signal and physical broadcast channel (SS/PBCH) block for master information block (MIB), and
• receive, from the base station, remaining minimum system information (RMSI) based on the MIB,
• wherein the MIB includes configuration information,
• wherein the configuration information includes a value indicating, based on a table, a combination of:
• information on a multiplexing pattern for the SS/PBCH block and control resource set (CORESET),
• a number of resource blocks for the CORESET,
• a number of symbols for the CORESET, and
• a resource block (RB) offset between an RB associated with the SS/PBCH block and an RB associated with the CORESET, and
• wherein the table is defined with respect to a subcarrier spacing of the SS/PBCH block and a subcarrier spacing of the CORESET.
