Abstract: Synchronization methods, apparatus and systems are disclosed. An example method includes storing, in memory of a device, schedule information indicating times at which the device is to listen for a sequential series of data frames, the schedule information further indicating a reference time at which transmission of the sequential series of data frames to the device is to be initiated; initiating a listening session at a first time of the schedule information according to a native clock of the device; identifying which of the data frames of the sequential series is received first during the listening session; and adjusting the native clock of the device based on the identified data frame.
