Communication of system information

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 including a primary synchronization signal (PSS) and a secondary synchronization signal (SSS);
• and
• a processor operably coupled to the transceiver, the processor configured to determine, based on the SS/PBCH block, configurations for a first control resource set (CORESET) to monitor a first physical downlink control channel (PDCCH);
• wherein the transceiver is further configured to receive the first PDCCH based on the first CORESET,
• wherein the processor is further configured to determine, based on the first PDCCH, (i) configurations related to a request for a system information block and (ii) configurations for a second CORESET to monitor a second PDCCH, and
• wherein the transceiver is further configured to:
• transmit the request for the system information block;
• receive the second PDCCH based on the second CORESET;
• and
• receive a physical downlink shared channel (PDSCH) scheduled by the second PDCCH, wherein the PDSCH includes the system information block.
