On-demand sib1 transmission

A user equipment (UE) in a wireless communication system, the UE comprising:

• a transceiver configured to transmit a request for a first system information block;
• and
• a processor operably coupled to the transceiver, the processor configured to determine a first time domain window for receiving a confirmation for the request,
• wherein the transceiver is further configured to receive the confirmation for the request in the first time domain window,
• wherein the processor is further configured to determine, based on the first time domain window and the confirmation for the request, a second time domain window for monitoring a physical downlink control channel (PDCCH) scheduling the first system information block, and
• wherein the transceiver is further configured to:
• receive the PDCCH based on the second time domain window;
• and
• receive the first system information block.
