Classification: CPC H | IPC H

Claim 13:
14. A base station comprising:
a processor configured to:
operate the base station in an operational frequency band; and
control transmission of one or more synchronization signal blocks (SSBs), wherein each of the SSBs includes Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), and Physical Broadcast Channel (PBCH); and
wherein the operational frequency band corresponds to a value L indicating a maximum number of the SSBs in a synchronization signal (SS) burst;
wherein, on a condition that the value L is less than a threshold L value, an SSB index is determined based on a Physical Broadcast Channel (PBCH) demodulation reference signal (DMRS) sequence,
wherein, on a condition that the value L is 64, the SSB index is determined by using both of the PBCH DMRS sequence and a PBCH payload,
wherein, on the condition that the value L is 64, the SSB index consists of least significant bits (LSBs) and most significant bits (MSBs),
wherein the LSBs for the SSB index is determined based on the PBCH DMRS sequence, and
wherein the MSBs for the SSB index is determined based on the PBCH payload.
