Method and apparatus of NR RMSI CORESET configuration in MIB
Configuring control information comprises determining a frequency offset including an RB and RE level frequency offset, where the frequency offset is determined based on a lowest RE of an SS/PBCH block and a lowest RE of CORESET for RMSI, jointly configuring, using a first field of 4 bits, the RB level frequency offset with a multiplexing pattern of the SS/PBCH block and the CORESET, a BW of the CORESET, and a number of symbols for the CORESET for a combination of a SCS of the SS/PBCH block and a SCS of the CORESET, configuring using a second field of the 4 bits generating an MIB including the RB level frequency offset and the RE level frequency offset; and transmitting, to a UE, the MIB over a PBCH.

22. A base station, comprising:
at least one transceiver; and
at least one processor, wherein the at least one processor is configured to:
transmit, to a user equipment (UE), a synchronization signal and physical broadcast channel (SS/PBCH) block for master information block (MIB), and
transmit, to the UE, remaining minimum system information (RMSI) based on the MIB,
wherein the MIB includes configuration information and offset information,
wherein a value of the configuration information indicates, according to 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,
wherein the table is defined with respect to a subcarrier spacing of the SS/PBCH block and a subcarrier spacing of the CORESET, and
wherein the offset information indicates a resource element (RE) offset between a subcarrier associated with the SS/PBCH block and a subcarrier associated with a resource block grid.

wherein the RB offset corresponds to a difference between a lowest resource block of the CORESET and a lowest resource block corresponding to the SS/PBCH block in a frequency domain,
wherein the RE offset corresponds to a difference between a lowest RE of the resource block grid and a lowest RE of the SS/PBCH block in the frequency domain,
wherein each RB corresponds to 12 subcarriers, and
wherein the RE offset is indicated according to four bits in the MIB.
24. The base station of claim 22 , wherein the MIB further includes information on the subcarrier spacing of the CORESET,
wherein the information on the subcarrier spacing of the CORESET indicates one of two possible values according to a frequency range, and
wherein the CORESET is associated with a physical downlink control channel (PDCCH) for the RMSI.
