Techniques for synchronizing based on sidelink synchronization signal prioritization

An apparatus for wireless communications at a user equipment (UE), comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive a first configuration from a first synchronization source, the first configuration comprising a first synchronization source identification associated with the first synchronization source;
• receive a second configuration from a second synchronization source, the second configuration comprising a second synchronization source identification associated with the second synchronization source;
• identify the first synchronization source identification and the second synchronization source identification are from a first set of synchronization source identifications associated with independent synchronization sources;
• select the first synchronization source based at least in part on a first priority associated with the first synchronization source is higher than a second priority associated with the second synchronization source, wherein determining the first priority is higher than the second priority is based at least in part on a comparison of a value of the first synchronization source identification and a value of the second synchronization source identification;
• and
• communicate with one or more devices using synchronization information associated with the selected first synchronization source as a synchronization reference.
