1. A user equipment (UE) in a wireless communication system operating with shared spectrum channel access, 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 higher-layer parameter ssb-SubcarrierOffset based on a master information block (MIB) of a PBCH included in the SS/PBCH block,
determine a bit (āĀ+5) from a payload of the PBCH, and
determine a first value (kSSB) based on a second value (kSSB), wherein:
if kSSB≥24, kSSB=kSSB;
if kSSB<24, kSSB=2·└kSSB/2┘; and
four least significant bits (LSBs) of the second value (kssp) are indicated by the higher-layer parameter ssb-SubcarrierOffset and a most significant bit (MSB) of the second value (kssp) is indicated by the bit (āĀ+5).
