This disclosure provides systems, methods, and devices for wireless communication that support synchronization signal block (SSB) configuration for narrow spectrum. In a first aspect, a method of wireless communication includes scanning one or more of a plurality of bandwidths to identify a synchronization bandwidth via which a SSB is wirelessly communicated. The plurality of bandwidths includes a first subset of bandwidths and a second subset of bandwidths. Reference frequencies of consecutive bandwidths of the first subset of bandwidths are separated by a first frequency step value and reference frequencies of consecutive bandwidths of the second subset of bandwidths are separated by a second frequency step value that is less than the first frequency step value. The method further includes receiving the SSB via the synchronization bandwidth. Other aspects and features are also claimed and described.
