1. A user equipment (UE) in a wireless communication system, the UE comprising:
a transceiver configured to receive a synchronization signals and physical broadcast channel (SS/PBCH) block; and
a processor operably coupled to the transceiver, the processor configured to:
determine a subcarrier spacing of the SS/PBCH block from a set of subcarrier spacings {15, 30} kilohertz (kHz);
upon determining the subcarrier spacing of the SS/PBCH block as 30 kHz, determine a frequency offset as one of 0, 1, 2, or 3 resource blocks (RBs) based on a configuration in a master information block (MIB) of the SS/PBCH block;
upon determining the subcarrier spacing of the SS/PBCH block as 15 kHz, determine the frequency offset as one of 10, 12, 14, or 16 RBs based on the configuration in the MIB of the SS/PBCH block; and
determine a frequency location of a control resource set (CORESET) based on the frequency offset,
wherein the transceiver is further configured to receive a type0 physical downlink control channel (Type0-PDCCH) based on the frequency location of the CORESET.
