Configuration for on-demand sib1

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

• receiving, from a cell of a first base station (BS), a first synchronization signals and physical broadcast channel (SS/PBCH) block;
• determining, based on an indication in a physical broadcast channel (PBCH) of the first SS/PBCH block, a first value of kSSB;
• determining, based on the first value of kSSB, whether the cell is associated with an on-demand system information block 1 (SIB1);
• transmitting, based on a determination that the cell is associated with the on-demand SIB1, a request for the on-demand SIB1 to a second BS;
• and
• receiving the on-demand SIB1.

A base station (BS) in a wireless communication system, the BS comprising:

• a processor configured to:
• determine whether a cell is associated with an on-demand system information block 1 (SIB1);
• and
• determine a first value of kSSB when the cell is associated with the on-demand SIB1;
• and
• a transceiver operably coupled to the processor, the transceiver configured to:
• transmit, to a user equipment (UE), a first synchronization signals and physical broadcast channel (SS/PBCH) block, wherein a physical broadcast channel (PBCH) in the first SS/PBCH block indicates the first value of kSSB;
• receive, from another BS, an indication for transmitting the on-demand SIB1;
• and
• transmit, to the UE, the on-demand SIB1 in the cell.
